This channel is literally the Holy Grail of the SFF community.
This channel is the reason I got into mini ITX builds.
Manu Shanboss This channel inspired me to build an itx and get back to pc gaming after 15 yrs
I can't wait for Big Navi Custom loop builds. I will rebuild his favourite :D
Manu Shanboss Totally agree. All hail to Ali!
This channel puts Dave2d to complete and utter shame. I mean just compare the two with their 3080 reviews. Dave2d just managed to gloss over thermals and noise. I get it most people doesn't have the attention span to watch super technical stuff like Gamers Nexus or Hardware Unboxed with their 30min videos (which I love) and prefer the aesthetically pleasing catered down stuff like Dave2d but this guy is on another level. He has all of the cinematics and minimal design of Dave2d while being well more informative and capable of catering to both the casuals and the enthusiasts.
FWIW. I tried the 600w Corsair gold on a 10900k stock with the 3080 FE. 2x16gb. 2 x 2tb nvme. Constantly shut down in aida64.
That's interesting! Do you remember what stress tests you selected? I'll see if I can replicate it on the unit I have here.
There’s a power limit on TUF version so the conclusion maybe invalid, other version could draw more power
Optimum Tech ya I just hit all the check marks. Including the gpu. I bought my PSU in 2016 and it’s actively been in use the whole time. Not sure if that would make a diff.
The reboots would occur sometimes within seconds of launching the test but would sometimes stay alive for a few minutes
Draw for me never pulled over 600w that I could measure before shutdowns
@@Dave2D yo what up Dave!
@@azkaban3000 There is a power limit on all versions. It's actually 20W higher on the TUF than FE.
You have no idea how valuable this video is to me
Exactly. Waiting to buy 3060 or 3080 with my stimulus money but had the question running around in my head if my EVGA 600w 80+ Gold was going to be enough. Then, as if by driven by Providence, I find this video.
Perhaps the price of a PSU?
@@dsandoval9396 so what you bought, btw is 5700g + 3070 enough for 650 watt gold?
1:24 I love how smooth these transitions look
Mate, you're an ABSOLUTE LEGEND for making this video. Been looking for concrete answers for ages. Thanks so much!
Same! This guy is a champ!
My guess is now another channel is going to do the same thing and act like they came up with it or change it just a bit. Lol
Joshua Keys Dave Lee didn’t do a test but already told in his 3080 review that 600w psus dont work.
So don’t act like u know everything.
@@amashaziz2212 I don't know everything. No one does. I watched D2D video as well. Never understood why people,such as yourself, on TH-cam have to have such animosity towards people when comments are left that you don't agree with.. All I said that another channel is going to take his idea since most tech channels show the same content.
Yes thanks for making this ...
This is literally the question I was asking my friends a few days ago.
You are SUCH a good source of information for SFF builds!
Absolutely stellar cinematography man, I swear each video it gets prettier with the visuals, especially in 4K,
solid testing and information as well!
Great video! As a beginner in the PC build world...your videos are simple and easy to follow and learn from.
Now we need a temp test of the sandwich layout when you get your hands in the founders edition
Yeah, but still shipping yet for FE card
FE cards are as much a paper launch as it gets it won't even let people get notify on Nvidia site
So, watching another video someone already made, can't remember his name, I believe he's English, the FE was almost 20* hotter than the Asus Tuff 3080.
can i run 3080 with i5 7500 on be quit pure power 9 HAHHA the budget mode :O
I think the FE will draw less power but make the system too hot because of its cooler design.
Man, thank you for helping the SFF community so much!
If you get the XC3 could you try it on the Dan A4 and similar cases? (I'm almost sure that you will anyways xD)
Would love an XC3.
EVGA pls.
Optimum Tech feel like you should get way more products based on how many views you have and quality of your content
@@optimumtech Have you tried reaching out to @EVGA_JacobF on Twitter? He's a pretty cool guy
Optimum Tech i can’t wait for your reviews of these new GPUs on the ghost S1, formD-T1, etc. This video of PSU compatibility is more than welcome. To be honest i hope you will make a video like a build guide with compatible elements for the different cases. Thx a lot and we will all see you in the next one.
@@optimumtech be quit pure power 9 80+ silver will work :O?
Wow! I'm so happy this channel has grown so much in such a short time! I remember when you had like 10k subs I knew you'd make it big. Your content is of high quality and I'm glad your sub count reflects it!
Thanks for all the great work you're putting in with the 3080 testing. Really appreciate it!
I think this is what lots of us were concerned about! Great to see the 600w barrier is safe. 3700x stock clocks here more than enough.
Thanks again!

This right here is probably the MOST important video about these video cards.
The SFF community loves you, you doing god's work my man!
The SFF is a form factor, it has NOTHING to do with power ratings... he could have run all of these tests on ATX form factor PSUs and the results would be applicable to every SFF form factor PSU out there. It was pointless to specify that this was an SFF form factor video, because it has nothing to do with the testing or results in this test.
@@wolfshanze5980 Except it isn’t pointless. I bought a Silverstone 600 watt SFX power supply for good chunk of change when that was the MOST power SFX power supplies could, well, supply. This was a PARTICULAR power limit to the SFF community as it was developing as you could already get 1000 watt ATX supplies for cheaper than what I paid. Many, many people bought the same exact power supply I did. Upgrading now to the recommended minimum 750 watts for the 3080 would cost $130-250 for an SFX format power supply depending on brand, which compares to as low as like $50 for a reliable ATX power supply if you didn’t buy a big one the first time.
It effects a higher percent of the SFF community and the effect would be more expensive to the SFF community.
Amazing my mate and I were just discussing this last night and said "If only Optimum Tech did a video on this to be really sure" and ding it was done. Ali must be telepathic.
I am spooked... I checked your channel for any new videos, I refreshed, and a video popped up! xD
Haha same here!
@@BrumBrumBryn I have a special gift where it happens for techtubers I am subscribed to! xD
I remember powering an OG i7/Xeon and two 5770 cards on a POS 500 Watt for years. The computer always worked fine and I never had any issues. Even when I did OverClock the CPU, the PC ran well. (:
Good video demonstration and I am glad I was able to see your results. These new GPUs are way more power hungry then I thought they would be.
JUST the info I was looking for. Thanks for taking the time!
This is great content, and one of the first to tackle the issue many users currently have. Glad to hear that my 650W Seasonic 80+ Gold PSU will definitely be enough, especially when I'm only aiming for a 3070. Good job Ali!
650W easy for a 3070.
I have one of those, and I'm rocking a Ryzen 5 2600 (65w TDP), so I guess it's safe to upgrade... even though I'm not actually planning on upgrading anytime soon.
Corsair RM650 gold. I decided to roll the die and not to upgrade it for the RTX 3080. System draw should be 550W, 100W headroom is not great not terrible.
@@TomBombFR I run the same set up. I think it should be fine. Tbh, I wan't planing on upgrading from my rtx 2060 either, but if what NVIDIA said about 3070 is true, well I'm drooling already. So I'll probably upgrade.
I have a Seasonic G 650w and 2080ti, with gsync on the psu gets veery loud. I dont know why the fan is so aggressive on seasonic psu, because its not that hot, the air coming out the psu is cold.
So happy to hear the results! Thanks again for your contributions to the SFF community.
This is great but Im wondering if these would be okay when everything plugged into the pc is taken into consoderation. Will the NZXT still work with 2x QHD Ultrawides, a couple hard drives, and 8 USB 3 devices plugged in?
Thanks for the nice and helpful review mate! I believe this is a concern that so many people especially the ITX guys have, yet you just answered. Cheers!

this guy could review art supplies I would still watch it fervently
Answering the real question on everyone's minds. Thanks mate!
Your insight into which videos users need is incredible! Thanks again.
would a SF450 be enough for a Ryzen 5 2600 + 2060 super?? SF600 has been out of stock for a few months now in my country.
SF750 is incredibly overpriced now, and I was a bit worried after Dave Lee’s video. Good to know my 600 can still work with the 3080
just make sure you get one with only 2 eight pins
How much is it where you live. I can get one for €150 which is not bad for platinum rating and individual sleeved cables
you can afford 3080 but you cry how expensive sf750 is you must be trolling

How the hell do you already have 1 dislike when the video was just posted. This channel is so underrated. So much info and great videos! Keep it going brother!
People are just weird, lol.
@@lottexy You can click on the three dots that show up when you hover over the video and politely ask the algorithm to not recommend specific channels or that you're not interested in this kind of videos. That's how I got rid of minecraft videos that kept popping up in my recommendations.
Those are 2000 series owners bro.
@@lottexy Once you click 'don't recommend this video' It'll come up with 'Tell us why'. Click that, and it will tell you why it's recommending these videos, it's probably becuase you watched a video with fortnite in it ages ago and forgot. You can then tick a box saying, 'don't recommend things based on this video' and you won't get any more fortnite videos!
Do u even know whats underrated means? Obviously this channel is not. Its overwhelmingly liked and praised channel. Its just not at linus level yet
so if I was gonna build my pc in the NR200P with a 650W Seasonic 80+ Gold PSU that would be fine right? Also would the temps be anything to worry about.
Was super curious about this. Thanks for doing it. My other question would be about what the thermals of the FE cards are like in an ITX case. Especially the NZXT H1.
HERO this is exactly the video we all needed. Thanks Ali for all the great content!
Quality content! Handling the questions we’re all wondering about.
hi ali. how much of a noise difference was there between the sf600 platinum and sf750 platinum? worth upgrading for that alone or no? i would have loved to hear a noise comparison between all of them
Really interesting video !! Much needed and appreciated great job !
Meh. I've had some bad experiences doing this. I ran my current system (420 watts from the wall) on a 450 watt psu. Everything was fine for about a year. Then I started getting weird crashes, lag spikes, and my SSD fried along with the sata port it was plugged into. Switched to corsair 600watt and no more problems (except my dead ssd and sata port). It was a PITA to diagnose this problem. I'd go for the 750 watt if I was going to do this. Its really not worth the time and money you might end up spending. JM2C.
420 watts from the wall AIN'T 420 watts in your system. the gold, bronze, white rating on PSUs denote EFFICIENCY. assuming you using a gold one & drawing 420 watts, you'd only be feeding 90 PERCENT of that AT BEST, which is 378 watts, to your system, which in turns means that your PSU would need to draw to the VERY LIMIT to provide just 405 watts. you're practically already straining your PSU despite numbers at the wall telling you that you still have room. it's lucky in your case that shit only happens after a year.
Here is your answer th-cam.com/video/aOYpOM8_aew/w-d-xo.html
dude , ur content is clean and obvious , thank u ♥
What is the smallest reasonable case to put these AIB 3080 inside? FormD in the 3-slot configuration, or something bigger?
Thank you so much! I looked everywhere trying to research this!
So what you're saying is my little 3600 and 650w setup is going to have more than enough power. Sweet.
@@Android-ng1wn I think it was Jay that did some benchmarking and used a 3600x clocked down and while yeah there's a little performance hit, it wasn't huge.

Thanks so much for making this! We were all wondering this haha. I'm sure even people running 600 and 650 watt power supplies in ATX systems also have the same concerns. The only other concern I'd have is about PSU long term degradation running it at the upper limit like that, especially if you load your system often for long periods of time.
It won't last. You run a small PSU hard, especially with such rapid and strong power draw of a GPU like the 3080 and you will eventually get voltage droop as the PSU falls out of spec faster. Shutdown. The newer Corsair stuff is built well with great ripple control, regulation etc and overbuilt but it's not a licence to abuse the hell out it and expect it to last.
@@Berserkism you are talking out of your ass. You have zero data, just stupid guessing. PSUs have 5 and 10 year old warranties for a reason. Stop spreading fake news
The Corsair sf750 only has 2 pci-e 8 pin cables...what cables did you use instead.
Awesome video as always! Would love to see you take a look at the ftw3.
Thank you 👏. You have finally answered the ONE question I had regarding the RTX3080 that no one tried to address.
My H1 sitting in a box waiting for the next gen Ryzen thanks you for this quality content!
How did you get the 3x8 pin PCIe power Gaming X Trio card to work with a corsair sf600 which only has 2 PCIe ports?
I just built a SFF gaming/work computer using b550-i strix and Corsair sf750 in the Ncase M1. I’m not good at making my own cables so I’m curious. What length should I go with on CableMods? Pretty much just need standard 24pin mobo, 8pin cpu, 1 Sata for water cooling, and a dual 8 pin for my graphics card. Any ideas for lengths for each cable?
Would have been useful to see benchmarks run with each power supply to see if any difference in performance and also some stress testing for longer periods of time.
Thanks for testing this. I was on the fence about going from a 2070s to a 3080 because I thought I'd have to get a new PSU.
Using a SFX psu, how do you account for the gpu three 8-pin pcie along with the MOB 6-pin pcie? I don’t know of a SFX psu that can support both. Thoughts?
So the NZXT SF650 was actually tested in the H1 case? I have the H1 with this psu and wondering if I need to get a 3070/RX 6800 or a 3080/RX 6800 XT and a Ryzen 5 3600...
Thanks Ali, i won't need to update my 600 mATX and now the question is, does the 3080 have enough space in a NCASE M1?
It's not a given. He didn't do the proper testing. Igorlabs.de has proven that the RTX 3080 (read: graphics card only) over a duration of 1ms can pull a peak power consumption of 500 watts. That's lab tested with certified top-tier professional equipment...
th-cam.com/video/IicO6d4JHvg/w-d-xo.html
Awesome video. I just recently upgraded my rig with a Ryzen 7 5800X3D and an RTX 3080, and I've been a little worried about my Corsair SF600 80+ Gold not being able to handle it. I did run Aida64 and Furmark simultaneously without issue, but it's still nice to see that someone else has gotten similar results. It's definitely given me some peace of mind.
It's going to run fine short term, sure, but you are putting a lot of stress of the components of the PSU. Long term it might be a different story, that should be a consideration.
@p It will be generally fine for most application, but you could encounter a game or program such as Doom Eternal that makes the GPU have a power spike that last in the order of micro seconds. Very short, which is not enough to affect average power consumption, but it could be enough to trip your PSU overpower protection. Both components would be working as intended, however, you could have a bad experience. That's why it is mostly recommended to buy an oversized PSU. If someday, GPUs no longer present such behavior, then you could do just fine with a 600W unit.
In regard to how good that specific SF600 plat model is, I wouldn't know unless you tell me the brand and specific model name, so I could research. I wish choosing a PSU was as easy as looking at the 80 plus certification, but sadly is actually a more complicated topic.

Thanks for the info. I have the NZXT H1 with a 3700x and at the moment a 1080ti ftw3 but just pre-ordered a 3080 xc3. Do you know if Seasonic ( I believe they are the manufacturer of the H1's psu ) make a pin compatible 750w psu to swap into the H1 so that we can keep the custom H1 cables?

Finally , some one with a useful benchmark, thanks.
this is great thank you! Please do the same when the AMD 6000s come out!! Thank you!
Hi there, Have you ever run these tests with Seasonic GX series? From 650 to 850? I heard that they tend to have sensitive OCP that trips when the 3080+ cards go into high transient loads.
Thank you for the great info...im also running a corsair sf600 on my ncase m1.. at least i have a peace of mind now that i can purchase an rtx 3070..
If you dont mind.. can i ask whats the name of your background tube light?
Amazing work, I think one thing that needs to be mentioned is even among RTX 3080 AIBs, there are vast variables, the TUF 3080 has 375W power limit, but the strix has 450W, so there's much higher chance for 600W to power choke with the strix than the TUF, that needs to be taken into account
That's the point. I wouldn't recommend a 3x8pin for 650W and lower PSU. If you plan to buy a 3080 and above with that specs, you should atleast get a 750W.
@@Kley96 You think a 750w it’s good enough for a ryzen 7 5800x and a 3080 ?
Welp the shortage of 700w bronze and 650w Gold (I faced in Egypt) late 2017 when searching for a PSU led me into getting a 850w Gold PSU
you could say: I came looking for bronze and I found gold
this is why i just used laptop.. two adaptor if i can run just one i just run with one... if need more power just put another one it... if i want to go on travel i just taken it with me.. and play with one adaptor..
The quality of your videos is amazing. Great videography.
Thanks for the video... Exactly what I've been looking around for!
So, I'm thrilled to hear that 600W will support the 3080 easily. My question is though, because my Pc has a number of RGB items (4x LL120, 1 16GB Vengeance RGB, + 2 LED Strips) Will I still be within the limit? My case is the In Win A1 ITX
Leds have a negligeable impact on power draw
@@mememaster8368 It's okay, I have since upgraded to a 850W anyway lol
Wondering whether a seasonic 550w platinum rated at 92% will be perfectly to use? Would this be somewhat similar to the average gold PSU rated at 600w?
Going to come down to how power hungry the CPU is I think.
Would have liked some more content on this aspect TBH. How does the SF450 fare with a stock Ryzen 5 3600, for example? I think that would have given some interesting insights.
I've revisited this video (liked and subscribed) now having an RTX3080 TUF 12gb and currently run a 760ax power supply from Corsair. This video is incredibly informative. Is there reasoning behind the recommended power supply? I assume this is based on a maximum or average power draw? My system is an older build but still runs very well. cpu i7-4790k and a gtx1070. I plan to build a new amd system with this GPU but I want to start using it now and also to validate my GPU is working ootb. Thank again for the video!
Are you going to be doing a fit testing with cases? I'm interested in the TUF version of the 3080. Wondering if it will fit in an NR200 with NF-A12x25's mounted on the bottom panel.
Glad to see that 600W is usable with the 3080. Thank you for running these tests for all of us! With current power supply prices now spiking, i'm glad people don't *have* to spend $200+ USD for a 750+ W model.
You should upgrade to a bigger power supply like a 1000w because it’s not good running a small psu at max capacity. Check out gamers nexus videos on it. That’s a fire hazard.
@@Gorilazz. just don't use cheap no name or gigabyte psu.
Should have mentioned something about efficiency ranges with power supplies. I believe their Gold/Platinum ratings are achieved at 80% of rated power, meaning that even though they may work on the limits as pictured here they may not be efficient. I would bet that getting the SF750 in order to make sure it's in it's efficiency range would pay for itself over time vs the SF600...
Thank you so much for this. It’s answering one if the biggest question I had for building a new system.
Great Vid!
I'd be curious to see how these do vs the 3090.
Man, thank you! You just saved me a lot of money!
Remember that if it’s pulling 500w out of the wall, your system is only taking like 450w since they are usually 90% efficient...
Indeed. I think most people forget about that when taking measurements from the wall. A 600W PSU will SUPPLY 600W and will take a bit more. Efficiencies are usually around 90-95% depending on which part of the curve the system is at, but drawing 600W from the wall would still mean 5-10% headroom!
power supplies have 600w in 12v rail itself and some more at 5v(about50a) and 3.3v(30a) so when choosing a cpu and gpu if the power draw meets the demand all is good
100 watts of heats can be dissipated very easily coz of almost 5-8x more surface area than a cpu Ihs(yeah) so yea all chill
@Johnfuse Ah, pardon me. I was using the SF600(plat) as the reference because I'm assuming it's what most people on ITX builds are sporting (including me). I did forget to mention that I'm on 230Vac (similar to Ali who's in Australia). Both of us get a slightly more efficient curve up to 94% peak (which I rounded to 95%) and staying above 90% under any significant loads all the way to max rating. Any non plat supply will definitely be lower though, especially his RM850x which he first presented as baseline, although he did a cursory mention of having observed spikes above 600W on the SF600 power supplies he tested.
@Johnfuse have a titanium PSU.
Can't believe I had to come so far down to see this comment.
Please upvote this.
This is not how you measure the power delivered by the PSU, the measure at the wall is the total consumption including the efficiency of the PSU. Assuming a 80% efficiency you can multiply the measurement by 0.8 to get a rough idea of how much the pc is consuming... But even then it's not ideal, because the efficiency/power draw curve isn't linear.
This information and testing is fantastic thanks as I was worried I'd need to upgrade my EVGA Supernova G2 650W PSU.
Can I safely use a daisy chain cable for my 3080? Should I run two seperate pcie power cables?
Can you do some testing with Cinebench and Furmark or Heaven running at the same time? These gaming tests aren't testing the theoretical maximum output of the system.
My System Pulls 600W with RTX2080 from the wall on full synthetic loads so i'll be interested to see if I can crack the limit of my 750W power supply once my 3080 arrives....... Whenever that may be.

This is a big issue that people haven't really covered yet because nobody can get the cards.
I have a new card RX 6800 XT MSI Gaming Trio X and my EVGA 750W Supernova G2 crashes due to power draw with a stock clock Ryzen 5600x and x570 mb. Most 3080s are more intensive. Lots of people are complaining of crashes. Many with 850W PSUs even. I encourage you to keep doing this type of content because people don't even know what to buy to fix their issue.
The other issue is power spikes caused at some points in games that are intensive with graphics or loading content. These transient spikes can be up to double what the card is normally doing.
I find the best one for me to try on is Elite Dangerous when jumping systems. If you run at 1440p, 120hz, ULTRA, 2xMSAA it will crash to reboot about 30%-50% of the time.
What do you reckon for multi rail PSUs? I've got a top quality 650W but only takes 30A on the GPU rail.

600watt might be fine for a while.. However I have this same exact dilemma when I was upgrading my GPU to a Vega 64. AMD also reccomending 750watt PSU but lots of people on the internet saying 600watt is enough for that GPU (My system is an itx i7 8700k non OC with corsair SF600 gold psu)
After running the card for almost a year suddenly I encounter many sudden crash when loading a game or during the gameplay that prompt the system to trip. Since then I upgrade to an SF750 and have no problem.
I think it’s safer to run a GPU with a PSU wattage that are reccomended by vendor.. Not only for the piece of mind but for a quiter system. imo as long as the power drawn from the PSU is around 80% of the PSU maximum power it is safe for the long run... Just my two cents ✌️
Oh yeah I gave the old SF600 to a friend running 1650 super and r3 3100.. so far he encountered no problem 😄
I want buy a Vega 64 but I have a psu 600w :'v
I have been running a 1080 Ti and 8700K, both at stock clocks for over two years. Never had issues with a Corsair RM650i. … I did however after one year, buy a Corsair HX750i, because it was a platinum rated PSU. It would also run my power consumption more in its middle range than the 650W. … Anyway am set for whatever comes, and I have a back up PSU that I can swap out easy. Just change over the PSU box, leaving the modular cables in place. (Except the motherboard power cable which has a different fitting on the PSU.)
@@threecats8219 Isn't it not recommended and bad to keep cables when swapping? or does Corsair use interchangeable modular cables between the models? Either way i'd feel a little dirty using old cables but that's just me 🤷♂️
@@sendhelp3828 Yeah the Corsair RM650i and HX750i which I have are modular. The cables were not old by any means. Neither are they dirty, because I use a case with filtered air-intakes. Inside my PC is clean, and it only ever gets at worst, a fine layer of dust. Then I just vac it, because I clean my CPU tower at least every year. Plus I go in my PC case often to do something or other, and if there is dust I clean. There is no harm at all leaving cables from one PSU in place to use with another PSU. The HX750i has ribbon cabling, compared to round cables on the RM650i, but that doesn't make any difference.
Afterthought. I suppose it would be a good idea to swap the cables for the GPU over. Since the HX750i GPU cables are possibly designed to take more current. At the moment I still have my 1080Ti in place, which was running on the old PSU and its cables. However the likelihood that the RM650i cables can't carry the current that the HX750i can, is slim. Better to swap them over when I get a new GPU though. Better to be safe than sorry. Yeah, thank you for leaving a message for me, otherwise I might never have thought to change GPU cables.
@@threecats8219 Hmm fair enough. I actually ended up doing a little research about it and came to the conclusion Corsair modular cables are actually compatible across the different series via this www.corsair.com/us/en/psu-cable-compatibility Where it states "The only difference between Type 3 and Type 4 cables is the pinout of the 24-pin ATX cable; all other cables (SATA, PCIe, etc) are the same." so that's the only thing to watch out for. Still stands that i just feel kinda sketchy reusing existing cables.
I have a plug with a readout to see how much my system draws while gaming so not surprised by these results but I do wonder if there are potential problems over time. The tests were for 30 mins, how well would these power supplies hold up to that kind of load over months or years?
The Cinebench power draw between stock and OC is massive! Didn't expect that big of a difference.
Thank you so much for doing this, you saved me about $30 usd
If you're worried about saving something as measly as $30, then you cant afford a $700 gpu, and a proper monitor to take advantage of it.
@@TheGauges420 It's obviously not only about $30. Savings can easily stack up to hundreds of dollars saved over time when upgrading multiple components.
@@TheGauges420 if he can save that 30 every month the savings would exceed the price of the 3080 over 2 years until 4000 series.
@@offset543 every month? So hes upgrading his GPU every month and saving $30 by not upgrading his PSU? It doesnt quite work that way, he isnt saving $30/mo but instead $30 over the life of the GPU as a whole, which can be anywhere from 2-5 years, which makes that $30 savings practically worthless.
@@TheGauges420 I'm saying $30 is not a measly sum. It's a whole months worth of payment towards a flagship card.
Doing God's work. Thank you for answering all the questions that everyone has about the new Ampere cards.
I'd like to see long term reliability on something like an OC'd 10900k and a 3080 on a 600W PSU. If it's constantly drawing near it's limit or slightly over the rated limit I wonder how it affects component life span
Yes I’ve been waiting for answers! I got a 650 in a itx case
If you need to uundervolt, then it's better going with a 3070
@@Android-ng1wn xD that won't make the psu produce more power xD
I'm going for a 3070 and I'm probably going to pickup a 600w psu
i have a 600w psu and I also want to get the 3070, hoping the 600w psu would suffice and last long. i was worried that it may work but potentially dmg the psu/other parts after a while :(
@@jkevinAH Everywhere I've seen people can say you can run it with a 600w, so even thing you could run it with a 550, so you should be fine. But, make sure your 600w psu is a good one (you probably want one that's at least silver certified).
I have intel i7-10700k with inno3d rtx3070 in Corsair Cv650w bronze 80+ and it reboots while heavy gaming.. so switched to Rm750w gold ..
What about the age of the PSU? How old are the ones you tested in this video? I got a 5 years old Corsair RM650i in a 8700K system and I'd like to know if the age of the PSU has any effect here when paired with a 3080.
Thank you for this. Please if you can mount the FE edition in Phanteks Evolv Shift Air. I want to upgrade my RTX Asus Trubo model. With FE of 3080. And I was wondering how it will preform. I Love that case and small footprint on my desk. It will be a bummer to chamge my case...
