UPDATE: Meanwhile I tested this PSU inside out. In my test it worked 12 hours at over 360W of constant load (Ryzen5 + RX480 of rendering work) without a slight hick up. Unfortunately I have no equipment to bring it up to 550W, but at the named 360W it was absolutely cool and quiet. The voltage was stable and the ripple on the 12V rail was under 70mV that is really good. To compare with my three times more expensive BeQuiet, that was at around 100mV. The active PFC is also true and is working, I tested it as well. Furthermore this PSU was tested and certified in the EU, I checked for the official registration and test results. They are not faked, like with many other cheap PSUs, but this PSU is only (!) certified for the EU and only for 230V. As far as I understand, this PSU is not available in the US. I guess, the world wide certification would be just too expensive for such a price. Still the missing short circuit protection on +5V rail worries me and in my opinion the cables should be thicker for the full 550W load, but I might be wrong in that regards. Unfortunately the missing over current protection seems to be a weakness of many modern PSUs today, even of the expensive ones. Otherwise this PSU was an absolutely positive surprise for me. It delivered better overall performance, than my much more expensive BeQuiet PSU and I definitely would buy it again.

Great video - just a bit of extra info. This is not an 80 plus PSU. This manufacturer has only had one model certified and that was MPB1000 in 2015 at gold. So this one may theoretically meet the spec but they should not be using 80 plus badging on it. You can check at the 80 plus site clearresult. Everyone should check that site before they buy a PSU to make sure that at best the same model is certified, or at worst that the manufacturer has lots of models certified.

Not quite, you have to take a closer look at the certificate. This is a 230V EU 80 Plus Bronze. The EU is important, since it has slightly higher requirements, than the normal 230V 80 Plus Bronze. For the EU Silver you need to get to over 87% of efficiency at 100% of declared load. This PSU gets only 86% hence "only" the EU Bronze.

Is it possible the 5V rail does have protection, but the resistance of the cables meant it didn’t trigger? Just thought it was unusual 12V and 3.3V both had it but 5V didn’t!
Unfortunately it is very common today. To common if you ask me. I don't know why, but many manufacturers just don't do any protection on the 5V rail. It is not used so much on modern PCs, so may be because of that, but I think, it is irresponsible though and I will never understand that.
@@necro_ware I have noticed a lot of new PSU's have the 5 volt rail powered by the 12 volt rail using a dc-dc converter. That could explain why there is no short protection.

I also measured the resistance and got 0,2 Ohm from the end of one cable to the end of another (they are bound in the PSU on one end). So, with one cable, it should be 0,1 Ohm.

Thank you for this test, really helpful. I tried finding more in depth tests for the Seasonic B12 BC 550W, which is 60+euros, but couldn't find any. Maybe the Seasonic has 5V SCP, maybe it doesn't. Maybe the Seasonic has even less ripple with 360W than under 70mV, or maybe not. Maybe the Seasonic makes less noise, maybe it makes more. The only thing I'm certain is that the Seasonic has Japanese capacitors, which is a big plus. I'm going to buy the Mars, I'm not going to use this PSU on old rare hardware, so I'm not very worried about the lack of 5V SCP and about the chinese capacitors. If you buy more of these kind of cheap hardware and make videos about them, I'll also watch them.
I am surprised about how many UK and EU products that do not have power factor correction, I found out that all the LED lights in my house are under 0.6
Why does the lack of 5v protection not actually bother you? You brought it up, yet still recommended this thing? I don't understand or agree with the conclusion.
I once bought a cheap 5 dollar PSU which was advertised as 450W but was 180W but it passed all short-circuit and burn-in tests except the OCP which was set too high. I still have it from 12 years back its just it rails voltage is low due to ageing capacitor.
Great review. Please do more of that ;-) I'd also recommend the Neodymium Magnet test on the wires next time. I have several PSUs and MolexPCIE adapters with apparently copper cladded steel wires or some other material that is clearly magnetic but looks like copper. Also, those MolexPCIE adapters can be of very bad quality if you're unlucky. If you have one that feels extra light then strip the wires and check the gauge. I have some with extremely thin strands inside that get warm and cause a considerable voltage drop.
Nice ideas, thank you. Especially the non destructive ones. As long as my channel is as small, I'd prefer not to destroy the electronics which I buy. If I don't like it, I still can send it back, but if I destroy it, it will be not possible.
Not to add anything to the table but this tip might be helpful. Thank you very much for tip. I have this PSU that could theoretically supply 480 watts and I was somewhat disappointed when the voltage drops more than 1 volt across a rather short span of wires. The wires itself is thinner than usual and this PSU caused my GPU to "crash" due to not getting proper voltage
The moment I heard "35€ power supply", I automatically thought "garbage caps". Do you happen to have an oscilloscope? Even with a very old scope, you can measure the output ripple for each voltage.
@@warrax111 120mV on 12V is absolute maximum as per ATX spec, and most decent PSUs stay (far) under 50mV, so 95mV is pretty crappy tbh especially considering that's at just roughly half load (265W)
Ich hatte mal ein ähnliches, billiges Netzteil von Xilence in meinem HTPC. Das war wirklich richtig gut. Vor allem unter den widrigen Umständen. Bisher hatte ich drei PSUs von Be Silence, die alle zu meiner vollsten Zufriedenheit ausgefallen sind. Spätestens nach zwei Jahren. Der Mist kommt mir nie wieder ins Haus. Wenn es was Gutes sein muss, geht nichts über Seasonic, die waren schon in den 1990ern das beste vom besten und sind es heute immer noch. Einmal brannte mir ein Netzteil fast ab, als ich nicht zu Hause war. Schlimmstes verhinderte der Blitzschutzadapter, der durchbrannte, bevor das Netzteil in Flammen aufging.
All tests I did so far didn't show any issues except the 5V short protection, which I was talking about. Meanwhile I even checked the ripple on load and it was only under 50mV on 12V rail. People can say what they want, but this is really an impressive PSU for the price. I didn't expect that.
Used before a Mars mpII 850. Often my computer booted, and got BSOD, restarted and it was fine, but when i moved the mouse, had a silent, high pitched noise from the psu. I buyed a new one, since then, i have no problems at all. I not recommend using this modell.
This is a MPB line not a MPII. The last one was a complete crap and the new one is a complete redesign. This time much better and with a real license and registration in the EU.
I have a 1000W Mars Gaming PSU - works fine, but is noisy as hell under load. My system is a Xeon W3690 on a Gigabyte UD4P paired with a RTX3060OC. Might switch it for a BeQuiet 750 just for the acoustics
There are different versions, it is very important to take the MPB and not the MPII version. The last one is loud and inefficient. The MPB got an official EU certificate and is very good. The one from this video is currently running in a Ryzen 5 5600 system with a RTX3070 Ti. Absolutely cool and silent.
@@flensburgerpilzproductions3141 Well, that one was only certified for 115V US, but not for the 230V in the EU. At least I can't find it in the lists. Looks like the most powerful Mars Gaming PSU, which was certified for 230V EU is the MPB850. Probably, there is something odd about the MPB1000, that it got no certificate in the EU. You can search here if you want: www.clearesult.com/80plus/manufacturers/115V-Internal
They are neither good nor bad. You have to search for particular model in the European register. The ones which were registered, like the one I showed in the video, are good, the others not. This company seems to have different models with huge quality deviation.
@@necro_ware Dude my computer vendor is selling me Mars MP II 750w 85modular for $20 brand new. As for me I don't have any special or specific knowledge of computer hardware. So what do you suggest should I go for it or not? My Pc specs I5 6500 Motherboard h110 16gb ram Rx 590 Nitro+ Sapphire 8gb 128ssd 500hdd
It is as always. A good quality PSU needs much more and heavier parts. A active PFC needs extra coils and higher power needs bigger transformers. So a good PSU is much heavier than a low quality one. Cheap PSU´s have the "high power" only printed on the case.
That's simply not true. Older PSU for example used heavy coils for passive PFC filtering and we're much heavier, than modern ones with active PFC circuit. That doesn't mean, that older PSUs were better. Deciding if an electronic part is better or worse comparing it's weight, means completely ignoring the progress. This very PSU, which you see in the video is currently powering a Ryzen 5 5600 with an RTX3080 Ti. Absolutely stable, cool and quiet. It was also officially tested and got an EU certificate delivering over promised 550W. All the data can be obtained from the official sites.
I've seen a deep test on this PSU on an italian TH-cam channel and he says that this PSU stop working at 300w and has very bad power efficency be careful
On exactly this one? I found two tests of this PSU here in Germany and they said, that the efficiency was superb :) Anyway, for what I'm doing it's more than enough and as I said, my review was just basic. I have no proper equipment to stress it more than I did. At least at 265W the PSU didn't even got warm after more than 12 hours of benchmarks.
Yes, I saw that. It was a different PSU. But anyway, I also would think, that for the price, it shouldn't be able to handle 550W. However, I'd be curious to know how much it would really do... the MPB seems to be a newer line, than what Dante tested.
It's funny by that price, but I really have no plausible reasons to say that. Meanwhile I opened it and it looks all just fine, I measured the voltage ripple and it is well within the specs. I didn't get manage to load the PSU with up to 550W, but at least at about 300W it behaved absolutely cool and stable over 24h of continuous stress tests. Still, everybody should understand, that for that price, there must be some "compromises" and nobody should expect some kind of magic. But I'd say for a low budget PC this PSU is may be good enough. And talking about reputable PSUs, I had an expensive BeQuiet PSU, which is IMHO quite reputable, I guess. That one exploded in fire after 4 months and took down my mainboard with it, so you can't rely on that. I was working in my life in a couple of very reputable companies, and once I've seen, what happened behind the scene, I stopped believing into the names ever since. Not everything is good or bad, don't get me wrong, I don't want to over-simplify it, but I saw no-name cheap Asian products, which were thousand times better, than the super expensive European pendants. Unfortunately you really know it first, when you take a closer look at both side by side.
[1] 500w can't even power a 980ti. [2] Just by looking in the vents, you can tell it's poorly made AliExpress junk. So i wouldn't believe anything printed on that box or in their ads.
You go and buy a 600€ PC and power it up with a questionable PSU that cost 25€? I mean the Capacitors may work, but how long 1 Year? because your overusing them? Buy dirctly a cheap Corsair, BeQuiet or FSP, and you are on the safe side.
I have two PCs with Ryzen 5 3600 RX570 and one Ryzen 5 5600 RTX3070 and guess what? Expensive BeQuiet PSU in the first PC died after 7 months and this cheap one powered for half a year one test machine and now runs since half a year in the second Ryzen 5 5600 machine. Cool and quiet. However, I don't suggest anything, just sharing my experience so far. Still waiting when the cheap PSU dies, simply out of curiosity.
I'd say stay away of these cheap chinese PSU:s. If you are on budget, go for a hunt for used ones etc. I bought mine from thrift store for 10€. Cooler Master GX750 is what I got, only issue with it was the fan, I replaced it with new one and works fine :)
I buy only ATX power with JAPAN or USA made capacitors! Made in China is......My experience, it is not worth buying cheap things and it does not matter if it is from a proven manufacturer! My ATX are 670 and 710watt. Then it cannot happen that individual branches do not give the required value at high hardware load or overclock! For example Fortron produced 550watt this Fortron HYDRO GE 550W with japan capacitors. Fortron give on some types 10years waranty! I trust them more than any tests.
At least since I was working for a German company which had a cooperation with another Japanese company, which sold a very expensive home electronics, I don't believe in that fairy tale anymore. Expensive doesn't necessarily mean good and cheap doesn't mean bad. In addition to that, a lot of products from China made a huge step into the direction of quality in the recent years. Many things can still be bad, but I wouldn't judge by the price or the country of manufacturing anymore. Also a lot of stuff with "Made in Germany" imprint is a total crap today.
My rule is don't run a cheap PSU on anything I can't afford to loose. My 3950x + 2080TI is on a pretty expensive 80+ titanium rated supply. What you have looks just fine for what your using it for.
Just as opposite example. Couple of years back I bought an expensive BeQuiet PSU, because I didn't want to have troubles with my main PC. After 4 months it exploded in fire and I didn't only have to throw away my whole PC, but also renovate my working room. Unfortunately, price doesn't mean much today as well. As I told in the video many PSU today, which you can buy don't have short circuit detection on 5V. Even the expensive ones :(
the rating is meaningless about durability and you don't need to go expensive to be safe. Just buy from respected manufacturers, like seasonic, evga, corsair (not the VS), superflower ecc..
@@gigigigiotto1673 I buy mostly all Seasonic. Having a strong electronics background I can spot the garbage most of the time. Want to blow up a PSU, use a modified sinewave UPS with Active Power Factor correction in the PSU.
Talking of price, I think, if you bought 3950x + 2080ti, there is no need to talk about how cheap the PSU should be. I don't think, that +/-50€ would make any difference in the overall costs :) I think, this is more interesting for someone, who is really on low budget.
funny that they had to state active PFC if it is rated as 80+ bronze. Also the use of "90% efficient" is a dead give away that this thing is not gonna be good. Bronze and 90% efficient is not a thing. more like 80 at best.
You are the second one, who asks :D I was fixing my dish washer and cut my finger on a metal edge inside. I recorded parts of this video in parallel as I was making the video about the GTX770. So it is already two weeks ago and meanwhile everything is fine, bat thank you for asking! ;)
I guess, that into this psu is guts from very bad knowing Aerocool VX, it has similar board and unsafe 5v line. This psu us very bad, i saw a lot of dead vx in my life.

Exactly, but it should make you think, that the efficiency is at least 80%. Anyway, unfortunately, I'm limited in my ability of testing it, so who know, if it's true?! However, I'd say it is at least quite efficient, since running benchmarks for over 12 hours without even getting warm was quite impressive.
I still don't know, if it can handle 550W, however this PSU turned out as a total surprise. Meanwhile I tested it at over 360W constant load over 12 hours. The PSU remains stone cold, super silent, stable and delivers very low ripple. I still can't believe how good it is. Don't be confused by the price. I learned that lesson a long time ago. In my main PC I have a BeQuiet PSU, which is 3 times as expensive and that one delivers worse ripple and gets a lot warmer. On the bad side though, I think the cables could be thicker and the missing protection on the 5V rail.

@@EvilTurkeySlices But still they putting they brand on it = need at-least be decent
Thank you for this test, really helpful.
I tried finding more in depth tests for the Seasonic B12 BC 550W, which is 60+euros, but couldn't find any.
Maybe the Seasonic has 5V SCP, maybe it doesn't. Maybe the Seasonic has even less ripple with 360W than under 70mV, or maybe not. Maybe the Seasonic makes less noise, maybe it makes more.
The only thing I'm certain is that the Seasonic has Japanese capacitors, which is a big plus.
I'm going to buy the Mars, I'm not going to use this PSU on old rare hardware, so I'm not very worried about the lack of 5V SCP and about the chinese capacitors.
If you buy more of these kind of cheap hardware and make videos about them, I'll also watch them.
I think I'll be sticking with my Evga GQ 750 from now on.
I am surprised about how many UK and EU products that do not have power factor correction, I found out that all the LED lights in my house are under 0.6
Yes, that's true and actually, they all are illegal. Fortunately this device has an active PFC. Meanwhile I looked into this PSU and it has it indeed.
Why does the lack of 5v protection not actually bother you? You brought it up, yet still recommended this thing? I don't understand or agree with the conclusion.
Because many modern and more expensive PSUs don't provide 5V short protection as well and because 5V rail is barely used on modern systems.
Can I use this ro power an rtx 2060 super or a 2080?
I once bought a cheap 5 dollar PSU which was advertised as 450W but was 180W but it passed all short-circuit and burn-in tests except the OCP which was set too high. I still have it from 12 years back its just it rails voltage is low due to ageing capacitor.
Great review. Please do more of that ;-) I'd also recommend the Neodymium Magnet test on the wires next time. I have several PSUs and MolexPCIE adapters with apparently copper cladded steel wires or some other material that is clearly magnetic but looks like copper. Also, those MolexPCIE adapters can be of very bad quality if you're unlucky. If you have one that feels extra light then strip the wires and check the gauge. I have some with extremely thin strands inside that get warm and cause a considerable voltage drop.
Nice ideas, thank you. Especially the non destructive ones. As long as my channel is as small, I'd prefer not to destroy the electronics which I buy. If I don't like it, I still can send it back, but if I destroy it, it will be not possible.
Not to add anything to the table but this tip might be helpful. Thank you very much for tip.
I have this PSU that could theoretically supply 480 watts and I was somewhat disappointed when the voltage drops more than 1 volt across a rather short span of wires. The wires itself is thinner than usual and this PSU caused my GPU to "crash" due to not getting proper voltage
Why didn't you open it up to look at the components and circuitry inside?
Because I was not sure, if I want to keep it.
I think in the case of using this PSU in a retro machine, my adaptation of your Voltage Blaster would come in handy, being an ATX based device. 😀
it works!
What about now 🙂?
Rx 570 / i5 4690k good?
The moment I heard "35€ power supply", I automatically thought "garbage caps". Do you happen to have an oscilloscope? Even with a very old scope, you can measure the output ripple for each voltage.
Hi, got about 95mV ripple on 12V at 265W overall load.
@@necro_ware is it good or bad? What is high and what is ok ripple value?
@@warrax111 120mV on 12V is absolute maximum as per ATX spec, and most decent PSUs stay (far) under 50mV, so 95mV is pretty crappy tbh especially considering that's at just roughly half load (265W)
Where did you get the PSU tester? Looks sturdy!
I don't remember. I think, I got it from Amazon years ago.
Ich hatte mal ein ähnliches, billiges Netzteil von Xilence in meinem HTPC. Das war wirklich richtig gut. Vor allem unter den widrigen Umständen. Bisher hatte ich drei PSUs von Be Silence, die alle zu meiner vollsten Zufriedenheit ausgefallen sind. Spätestens nach zwei Jahren. Der Mist kommt mir nie wieder ins Haus. Wenn es was Gutes sein muss, geht nichts über Seasonic, die waren schon in den 1990ern das beste vom besten und sind es heute immer noch.
Einmal brannte mir ein Netzteil fast ab, als ich nicht zu Hause war. Schlimmstes verhinderte der Blitzschutzadapter, der durchbrannte, bevor das Netzteil in Flammen aufging.
Was using same model but 850w version, using on my rtx 3080 with 13700k any many rgb's😂, a year now so far so good without any issues.
MpIII? Version
Hello, can I use it on my collection?
-ryzen 5 5600g
-asus tuf gaming b550m plus wifi
-rtx 2060 super 8gb
It would run, but you should get at least 650W PSU, since RTX2060 gives high voltage peeks.
You did not disassemle it!! Why?? ))
Since I didn't know if I'll keep it.
Is this power suply ok for i7 9th gen and gtx 1660 or should i upgrade as fast as posible
All tests I did so far didn't show any issues except the 5V short protection, which I was talking about. Meanwhile I even checked the ripple on load and it was only under 50mV on 12V rail. People can say what they want, but this is really an impressive PSU for the price. I didn't expect that.
Used before a Mars mpII 850. Often my computer booted, and got BSOD, restarted and it was fine, but when i moved the mouse, had a silent, high pitched noise from the psu. I buyed a new one, since then, i have no problems at all. I not recommend using this modell.
This is a MPB line not a MPII. The last one was a complete crap and the new one is a complete redesign. This time much better and with a real license and registration in the EU.
@@necro_ware Thanks for the research, and for the quality content! Keep up the good work!
I have a 1000W Mars Gaming PSU - works fine, but is noisy as hell under load.
My system is a Xeon W3690 on a Gigabyte UD4P paired with a RTX3060OC.
Might switch it for a BeQuiet 750 just for the acoustics
There are different versions, it is very important to take the MPB and not the MPII version. The last one is loud and inefficient. The MPB got an official EU certificate and is very good. The one from this video is currently running in a Ryzen 5 5600 system with a RTX3070 Ti. Absolutely cool and silent.
@@necro_ware I have the MBP1000
@@flensburgerpilzproductions3141 Well, that one was only certified for 115V US, but not for the 230V in the EU. At least I can't find it in the lists. Looks like the most powerful Mars Gaming PSU, which was certified for 230V EU is the MPB850. Probably, there is something odd about the MPB1000, that it got no certificate in the EU.
You can search here if you want: www.clearesult.com/80plus/manufacturers/115V-Internal
In conclusion tell me supplies of this brand is good or not?
They are neither good nor bad. You have to search for particular model in the European register. The ones which were registered, like the one I showed in the video, are good, the others not. This company seems to have different models with huge quality deviation.

It is as always. A good quality PSU needs much more and heavier parts. A active PFC needs extra coils and higher power needs bigger transformers. So a good PSU is much heavier than a low quality one. Cheap PSU´s have the "high power" only printed on the case.
That's simply not true. Older PSU for example used heavy coils for passive PFC filtering and we're much heavier, than modern ones with active PFC circuit. That doesn't mean, that older PSUs were better. Deciding if an electronic part is better or worse comparing it's weight, means completely ignoring the progress. This very PSU, which you see in the video is currently powering a Ryzen 5 5600 with an RTX3080 Ti. Absolutely stable, cool and quiet. It was also officially tested and got an EU certificate delivering over promised 550W. All the data can be obtained from the official sites.
I've seen a deep test on this PSU on an italian TH-cam channel and he says that this PSU stop working at 300w and has very bad power efficency be careful
On exactly this one? I found two tests of this PSU here in Germany and they said, that the efficiency was superb :) Anyway, for what I'm doing it's more than enough and as I said, my review was just basic. I have no proper equipment to stress it more than I did. At least at 265W the PSU didn't even got warm after more than 12 hours of benchmarks.
@@necro_ware the channell is dante's hardware it has tested a mars gaming 550w if you want i can give you a link of the video
Yes, I saw that. It was a different PSU. But anyway, I also would think, that for the price, it shouldn't be able to handle 550W. However, I'd be curious to know how much it would really do... the MPB seems to be a newer line, than what Dante tested.
@@Androx74 Here in Italy TH-cam PSU testers are Falco (the Gold One), Dante, Saddy and Marco Verdoliva. Ciao
I buy a lot from this brand. It's cheap but reasonable quality. Their mechanical keyboards are really good.
Id pass on that when for a few more bucks you can get CS450 with more power on teh 12V rail and much better quality.
Nice video
[3] My EVGA has short protection on all rails. It is as good, or better, than any claim for their PSU product.
That thing is a time bomb. Spend extra money on reputable PSU's folks.
It's funny by that price, but I really have no plausible reasons to say that. Meanwhile I opened it and it looks all just fine, I measured the voltage ripple and it is well within the specs. I didn't get manage to load the PSU with up to 550W, but at least at about 300W it behaved absolutely cool and stable over 24h of continuous stress tests. Still, everybody should understand, that for that price, there must be some "compromises" and nobody should expect some kind of magic. But I'd say for a low budget PC this PSU is may be good enough. And talking about reputable PSUs, I had an expensive BeQuiet PSU, which is IMHO quite reputable, I guess. That one exploded in fire after 4 months and took down my mainboard with it, so you can't rely on that.
I was working in my life in a couple of very reputable companies, and once I've seen, what happened behind the scene, I stopped believing into the names ever since. Not everything is good or bad, don't get me wrong, I don't want to over-simplify it, but I saw no-name cheap Asian products, which were thousand times better, than the super expensive European pendants. Unfortunately you really know it first, when you take a closer look at both side by side.
[1] 500w can't even power a 980ti. [2] Just by looking in the vents, you can tell it's poorly made AliExpress junk. So i wouldn't believe anything printed on that box or in their ads.
well it did not explode like the Gigabyte supplies did LOL
You go and buy a 600€ PC and power it up with a questionable PSU that cost 25€? I mean the Capacitors may work, but how long 1 Year? because your overusing them? Buy dirctly a cheap Corsair, BeQuiet or FSP, and you are on the safe side.
I have two PCs with Ryzen 5 3600 RX570 and one Ryzen 5 5600 RTX3070 and guess what? Expensive BeQuiet PSU in the first PC died after 7 months and this cheap one powered for half a year one test machine and now runs since half a year in the second Ryzen 5 5600 machine. Cool and quiet.
However, I don't suggest anything, just sharing my experience so far. Still waiting when the cheap PSU dies, simply out of curiosity.
Cheap and cheerful.
I'd say stay away of these cheap chinese PSU:s. If you are on budget, go for a hunt for used ones etc. I bought mine from thrift store for 10€. Cooler Master GX750 is what I got, only issue with it was the fan, I replaced it with new one and works fine :)
I buy only ATX power with JAPAN or USA made capacitors! Made in China is......My experience, it is not worth buying cheap things and it does not matter if it is from a proven manufacturer! My ATX are 670 and 710watt.
Then it cannot happen that individual branches do not give the required value at high hardware load or overclock!
For example Fortron produced 550watt this Fortron HYDRO GE 550W with japan capacitors. Fortron give on some types 10years waranty! I trust them more than any tests.
At least since I was working for a German company which had a cooperation with another Japanese company, which sold a very expensive home electronics, I don't believe in that fairy tale anymore. Expensive doesn't necessarily mean good and cheap doesn't mean bad. In addition to that, a lot of products from China made a huge step into the direction of quality in the recent years. Many things can still be bad, but I wouldn't judge by the price or the country of manufacturing anymore. Also a lot of stuff with "Made in Germany" imprint is a total crap today.
My rule is don't run a cheap PSU on anything I can't afford to loose. My 3950x + 2080TI is on a pretty expensive 80+ titanium rated supply. What you have looks just fine for what your using it for.
Just as opposite example. Couple of years back I bought an expensive BeQuiet PSU, because I didn't want to have troubles with my main PC. After 4 months it exploded in fire and I didn't only have to throw away my whole PC, but also renovate my working room. Unfortunately, price doesn't mean much today as well. As I told in the video many PSU today, which you can buy don't have short circuit detection on 5V. Even the expensive ones :(
the rating is meaningless about durability and you don't need to go expensive to be safe. Just buy from respected manufacturers, like seasonic, evga, corsair (not the VS), superflower ecc..
There is a big issue right now with a GigaByte branded PSU.
@@gigigigiotto1673 I buy mostly all Seasonic. Having a strong electronics background I can spot the garbage most of the time. Want to blow up a PSU, use a modified sinewave UPS with Active Power Factor correction in the PSU.
Talking of price, I think, if you bought 3950x + 2080ti, there is no need to talk about how cheap the PSU should be. I don't think, that +/-50€ would make any difference in the overall costs :) I think, this is more interesting for someone, who is really on low budget.
funny that they had to state active PFC if it is rated as 80+ bronze. Also the use of "90% efficient" is a dead give away that this thing is not gonna be good. Bronze and 90% efficient is not a thing. more like 80 at best.
Well, suprisingly it is that good. See my pinned comment.
But the real question is: What happend to your finger? :)
You are the second one, who asks :D I was fixing my dish washer and cut my finger on a metal edge inside. I recorded parts of this video in parallel as I was making the video about the GTX770. So it is already two weeks ago and meanwhile everything is fine, bat thank you for asking! ;)
Wonder about Bronze.
I guess, that into this psu is guts from very bad knowing Aerocool VX, it has similar board and unsafe 5v line. This psu us very bad, i saw a lot of dead vx in my life.
Long term test is still on going. It powered my test machine for half a year, now since 5 months in a Ryzen 5 5600 with RTX3070. Runs fine so far 😁

also its locked to the 200-240v range seems pretty trash to me a non universal voltage supply like that i would consider junk
What a pointless reasoning.
"80+" is a branding name, it means nothing. :)
Exactly, but it should make you think, that the efficiency is at least 80%. Anyway, unfortunately, I'm limited in my ability of testing it, so who know, if it's true?! However, I'd say it is at least quite efficient, since running benchmarks for over 12 hours without even getting warm was quite impressive.
For just 10 euro more u can get a real psu, this one is just pure shit, 550w ? Yes of course i have 3 balls 🤣
I still don't know, if it can handle 550W, however this PSU turned out as a total surprise. Meanwhile I tested it at over 360W constant load over 12 hours. The PSU remains stone cold, super silent, stable and delivers very low ripple. I still can't believe how good it is. Don't be confused by the price. I learned that lesson a long time ago. In my main PC I have a BeQuiet PSU, which is 3 times as expensive and that one delivers worse ripple and gets a lot warmer. On the bad side though, I think the cables could be thicker and the missing protection on the 5V rail.
@@necro_ware for the same price u can buy evga 450 bt (or BR version)😉
