The 90 plus platinum certification not being platinum color isn't what concerned me...
It's the fact that they didn't even manage to spell Platinum correctly
I think this is intentional.
90 PLUS Platitum is a great upgrade from 80 PLUS Glod
90 Plus Platitude
I think it actually read 'PLATITUM' or something. 😅
They didn't spell platinum wrong, they spelled platitum right.
I love how Linus talks about the Platinum rating on the side but doesn’t even realize it says “Platitum”
THIS SHOULD BE PINNED
I missed that too! Get this guy to the top.
I assume they did and cut it...but yeah
Wait a second...they actually did misspell that LOL
Latest and greatest Platitum rating.
That label is wonderful.. There is also the "180-240V 10A" rating, which tops up at max 2400W input, for 3450W output, for an efficiency about 143%. Of course they gave it the golden-platitum achievement
230V times 16A = 3680W
So whats your problem?
@@010falcon The label on the power supply indicates that it only takes 10A
140+ *Platitum*
i was searching for this comment XD. @ like 390V we can slowly talk about 3450W
@@010falcon apart from the label saying only 10A: that actually what the C13 plug is rated for basically everywhere on this planet. It would need a C19 for 16A.

Insurance for equipment or life insurance?
@@Alias_Anybody Or.
@@Alias_Anybody yes
Jokes on you I opened my PSU and it yet didn't become a fancy creeper, I'm using it now.
@@inqizzo they've already had an accident lol. When Anthony opened the Mac, the capacitors discharged.
The sheer amount of trust that you guys put into that question mark of a power supply blows my mind.
Given how 5:16 went, I think it blew _THEIR_ collective mind as well
The trick was working out how it was going to go bang and making sure it's somewhere safe before it gets plugged in
indeed. one would think that these guys would be able to cobble together an electronic load that could more easily and cheaply test it to the rated power; but I suppose that wouldnt make for a video as entertaining and risky as this.
The dynamic between Linus, Alex, and Kyle is fucking hilarious. Kyle should basically just be a default co-host for these types of videos, if for no other reason to protect Linus and Alex from themselves LOL

@@crylune i hink they mean the power cable melting and what 3080uses 450 watts?
@@Peanutnibbler if you're melting cables with a 3080 or 4090 or whatever then you are doing many things very horribly wrong
@@the_undead even Nvidia admitted this was an issue, it was adapters not cables or the cards, no one user was at fault. this is why you should never cheap out on components. Some companies have no integrity.
@@crylune The 4090 founders uses the same as the 3080, the AIB aftermarket cards do NOT. They use more power than the 3090, 400-500w. If you OC them it can go over 600w.
As an electrician its totally fine to draw 3500w on a 230v circuit. You should get outlets that are rated for 16A continuesly and not just 16A Peak (10A continuesly), but other than that you are fine. A 16A circuit breaker wont even do anything unless you draw at least 14% more which is just slightly above 18A
I mean yeah, 230*16=3680
@@SzymonPmc to be fair, if you drawing 16A you are most likely not going to have 230v on that outlet anymore. Voltage drops with high current due to the resistance of the wire. You would need really THICC wire to keep it at 230v

I love how Linus tells Alex to get the render server as a joke and then freaks out when he sees/hears how expensive the *actual* test bench is.

lol this fucking loser. fuck your winners and go to hell.
It's great to see how comfortable Kyle has gotten in front of a camera in just a few short months. He has only been on camera a handful of times.
You know you're getting into sketchy territory when both Alex and Kyle have to be the voices of reason to Linus.
Apparently the "BANG" in Banggood is supposed to be the sound you hear before your 3450W PSU toasts all your components (and quite possibly your house)
your face, your hands, your partner, pets, and one free child(more than one and youd have to pay taxes), yk, theyre all about inclusivity over in china
Banggood - it makes a good "bang".
PSU link?
well at least the bang is good
sorry
Before it toasts, it fries with hot capacater oil.
I appreciate Alex standing up to Linus to protect the render box.
A good employee does his job, the best employee does his job and makes sure his boss doesnt fuck up too
And also the foresight to ensure that he didn't know, thus the answer couldn't be extracted or compelled out of him.
@@ferlessleedr exactly, social aikido really
Also makes for funny content I guess
The fact that you had to repair it when it was brand new is pretty damning, but good on you for taking it apart and checking it, especially with how sketchy that is. I'm honestly amazed it didn't start smoking or kill all those 3080s.
I love those kind of LTT videos. Having Linus being all smiles around super sketchy things is where you guys really make your best content.
it's like steve irwin but computer
You know the GPU stock situation is improving when Linus can put on death row 6 RTX 3080s.
It's definitely plunged, but unfortunately, it's not dropping anymore at this time.
they even find one more mid video to put on death row.

Thankfully it got better to a point where I could finally upgrade from a 1060 to a 6600 XT.
First Linus steals my beard, and now he's stealing my hats!
THIS WILL NOT STAND, SIR!
Hey
But he can't steal you good looks and charisma!
m'lady
You still have your fine taste for good alcohol, though.
well you gotta steal something back man if you just stand still like that no wonder he be ripping you off
I love how Linus points out the input voltage rating, but totally ignores the input current limit of 10 amps right next to it.
I was hoping to see some kind of generator like tony starks ark reactor inside, as that 10 A input limit gives a max output of 2400w at perfect efficiency on 240, so at a minimum it needs to pull 1050W out of thin air to attain rated capacity. If you were the low end of the input rating, it would need to probably draw near on double the rated input, if not more.
Chinese translation is bad and I am pretty sure it was saying 10Amps X2 or per unit but you gotta understand one thing.
Asia uses an open air cable system and power reaches each house after 2-3 freaking block lvl transformers and countries have something known as Nation wide grid, where if one producing unit is faulty it is compensated by other units.
So Yep our voltage is usually very very stable.
That must be an issue with the labeling then, as they achieved over 2400w in their limited testing.
@@UsmanSiddiq1 The 10A is the rated power of the C13 connector. The PSU only has one. Its power rating suggests that it draws more than 10A. It does not matter how stable the power grid is
Even in the UK, where we have 240v wall power, the max rated from one socket (unless you run a fresh breaker at higher rating) tends to be 13A .
Now it's nice getting 3120W, but still a few watts short of this power supply's advertised rating
@@RJ-wx3fh The issue is not the wall power, at least in Germany, it's limited to 16A, it's the C13
I genuinely really enjoyed this video. Not for the subject, but to see you guys just work together to achieve something. Feels like a bunch of friends working together.
Very true, in general these videos are much more genuine than product reviews an the like. Obviously different in nature, these videos are what keeps me subscribed opposed to other tech channels on TH-cam

Underrated comment.
Alex legitimately hiding the expensive equipment so Linus can't blow it up is brilliant 😅

@@robivlahov He's freaking out about the Threadripper CPU, those things are so hard to find at reasonable prices.
@@fritzceo9194 he sait it was 1.3k for the mbo ... A server is surely more expensive as rhe staff hid it
@@robivlahov Yeah, Threadripper Pro boards are expensive to begin with, and it's even more expensive for the Threadripper itself, it's hard AF to find one at a reasonable price. They have 7-8 3080s and the Camino server is replacable. It's Linus, he doesn't really care about net worth. What he does care is how rare that threadripper is.
@@fritzceo9194 plenty of cpus , the gpus were the peoblem
I've never been so on edge with an LTT video before, I was holding my breath when they opened up the 2 PSUs, one of which I don't think should exist.
@LTT Team: I received my screwdriver. It's amazing. Thank all of you. Please keep making that hat (or a suitable substitute) appear around Linus.... forever.
Your enginerds likely know about solder sleeves and western union splices. If they don't..... eh... recommend against wire nuts with stranded wire. Proper splicing with sleeving would've taken the same amount of time but would result in.... an actually safe product. This is important when you have so many hands in the area. It's even more important when you have one or more electronics muggles working on the product. Btw, have you guys considered putting a couple fire extinguisher mounts under that table? Sounds stupid until it doesn't. Then it REALLY doesn't.
Including the "customers also bought this" item was a nice touch. Please do that more often. 🙂
Linus is actually slaying that hat. I love it with the beard

I know it's a common occurance now to see LTT open power supplies, but, while they might do it, I can not stress enough that no average joe consumer should open one, especially one that's been powered on in the last week or so, the chance of extreme static discharge that could result in cardiac arrest is pretty high
Good to know, I had no idea.
This comment should be pinned
This is why when companies repair them, they should use insulating gloves, ensure they are not grounded, and short the power supply to get rid of any charge before they work on it.
Who knows, they might do that... The key word used here was companies, in other words someone who employs professionals to do this with a lot of know how, a heck of a lot more than I have.

Added myself to the waitlist. Got excited by the sold out jacket I saw.
Also, I once broke a power supply and the power switch was locked in the ON position. It was weird. I was able to return it and got a slightly better one IMO

3kW through a C13 power connector isn't that unusual in Europe. That's how most kettles are connected to the mains, and we generally describe the C13 as a "kettle plug", even when it is used in other devices.
yup, we got plenty of appliances that exceed 3000
I'd like to see those kettles. I don't think they actually draw 3 kW, because C13 is only rated for 10 A. Even with 230 V, you would be well beyond that rating.
C13 power sockets are rated for 10A, which is 2300W to 2400W with a proper electrical grid. Everything above that is out of spec and might melt the connector or socket.
@@anlumo1 If 13A melts the connector, it was never a 10A connector anyway
Not in EU but in UK
6:54 that is an PTC (Positive Temperature Coefficient) that is used to limit in-rush currents and not an NTC. As a high current passes through it and it warms up, it's resistance increases (hence Positive Temperature Coefficient) and it therefore limits the current, after the capacitors have charged up, the current decreases, the PTC cools does and it's resistance goes down and it has done it's job. a NTC would let more current through as it heats up, which is not what we want in in-rush current protection application.
That is exactly what you want in in-rush current protection?... Small start current, increasing to full capacity after the capacitor is filled... What you're describing is full in-rush current (instantly trips the breaker) followed by lower current (too low to run the full 3KW psu)...
@@someguy4915 I believe you're more correct on this one actually after I rechecked the use cases for the input protection cases for the NTC and PTC. PTC is more suited for possible short-circuit events, so they limit in those cases the more sustained current draw times. And I might have also mixed them with polyfuses, which share the PTC characteristic thermal-resistance behavior with current. Both can be used in current limiting applications.
Still waiting on that stress test of this power supply...
The way Linus handles electricity, I'm surprised he's still alive.
@AzenStreams My first experience with Electro Boom was him nearly electrocuting himself and actually lighting himself on fire trying to build his own seat warmer. It worked a little too well. lol
he's got the RECTIFIER's blessing
@@walterkovacs61 A full-bridge rectifier.
For those who doubt the danger of a power supply...
Even as a kid, I had the sense to not plug things in before testing sketch stuff. It was a REALLY old power supply, where you had to plug the leads into the power supply... but the sticker was gone so I didn't know which side to have the different pairs.
So, I plugged it into the wall and used a stick to flip the power switch, and it promptly exploded. Fortunately, it was not a big enough explosion to break the steel casing but it definitely set off the smoke detector.
Search youtube for "killing a capacitor"...
I had one go bad. It would shoot a arc of voltage out of the hdmi cable every time you tried to plug it into the tv. Weirdest thing ever. It wasn't just a quick spark either, a full solid arc like a stungun that would jump from the cable to the tv's socket lol.
I see linus has a lot of fear against live wires, even more at 220v. I used to use a soldering iron with a lot of spots in the cable burned from the soldering itself. One time I got shocker in the leg while simultaneously touching with my hand a metal cage connected to earth. I received a shock (220v), moved a bit scared out of surprice and continued soldering. Nothing too bad. The problem is when you grab the cable with out hand while earth connected, but touching it with a finger it wont kill you
haha, that was just a blown cap. it's fun when you just connect them directly to 230v and watch em blow, or use a small torch on the side of them (they are supposed to blow at the top) and shoot the hot blown insides at people XD they stink tho (like toxic gasses should) so do it outside
To clarify this was a catastrophic failure. I couldn't even pick up the box for some time because it was so hot. It was a lot more than a blown cap. This was a supply that hadn't been plugged in for a decade that had power flowing the wrong way through it, probably shorting as it flipped the breaker as well. But at that point I was like... these things are freaking death machines...
Love how they completely omitted how they incorrectly hooked up the power meter and kept hush about it.
Hooked up incorrectly (whole cord through transformer @11:47), and in the cut @11:49 it's magically hooked up right (one side only through transformer).
Judging by recent events this is forshadowing. I noticed it too.
Did they ever go back and test this on an actual PSU tester like they said they would?
They never follow up on their promises. I still remember the cable tester they only used for like two vids.
"the resistor is the wrong way around!"
Linus: "no it's not."

@@DeltaNrOne Did you miss the bit where he said the board was 1400 on its own? That leaves 1600 for all the rest and at a minimum those GPU are more than 250 each. So 3000 is far too low a guess.
I love it when LTT 'teamwork it' to 'find the holes they're targeting'.
Take it from a physiology grad and electronics nerd of 40 years, even a mains capacitor in a small PSU would 100% be able to yeet you across a room (and potentially kill).
A battery powered TENS machine is enough to make people punch themselves in the face or fall on the floor.. It's your muscles which do the real work, the electricity just has to be enough to trigger the nerves. Depending which particular muscles contract, it'd be able to throw you further than you could willingly jump, so depending how jacked you are, across the room is 100% possible.
SMPS bus caps are DC, so they'd usually cause one violent muscle contraction rather than the paralysis seen with AC electrocution. The bus voltage on a 230V powered PSU is 325VDC, enough to push 800mA through a person (Assuming the 400 ohm human model used in TASER testing). 10mA is enough to cause strong muscle contractions, 30mA can stop a heart.
having expensive ass equipment hidden from you by your employees is hilarious to me.

I can't believe I missed this video. Actually really interesting!

I'm a little tired of people copying GN on every front. Of course LTT get a PSU tester now instead of years ago... Right after GN received theirs and puts out some videos. Meh
@@Zombified- I think you have some fundamental misunderstandings about the difference between LTT and GNN... They are very different tech channels. LTT does more experience and power oriented content, with a bunch of whacky shit inbetween, while GNN does more results, raw power, and usability of devices, and have always been way more technical than LTT. LTT is branching into more technical content, which does mean that of course there will be some overlap in the technologies they use, but I really doubt Labs will be stepping all over GNN's feet. The scale Linus is trying to take Labs to is on another level entirely, if he succeeds. GNN will always have a place on this platform, Linus and the team wouldn't want to erase them entirely. They're all good friends.
Alright sorry for the couple of paragraphs, I'm just passionate about the content they both create.
12:22 a smart man, to stop a kid like linus.
Indeed
They have cheap Uni-T current clamp meters on Amazon. We use them all the time at work for rough current AC and DC measurements
You guys should hook up your equipment with Plug Type G on a decent Transformer. I use Type C/F and Type B & Type A pretty evenly depending on what project I'm working on via a general use Transformer and usually I have considerably fewer fatal occurrences as a result of mistakes during testing. Not only is it locally fused, it has lower resistance on connections as they are much thicker. Makes life a lot simpler. Foolish to do so but sometimes I use the wrong connector for the unintended voltage and even in those situations I usually am saved by Type G. Definitely more reliable with higher voltage as well. Doesn't struggle to draw current quite as much. Fair enough it is a small difference, but it is always somewhat more practical as a result, even if in the slightest form. I feel the appliance connection situation is similar to the failure to switch to Metric. It is so common and standard, it will be a catastrophe to switch now.

so its cutting it reeeaally close )
Even then the C14 inlet is not rated for 3450W. You need a C20
@@jonathanbuzzard6648 in germany we just need a normal shuko for that. Its Rated up to 16A which is 3680w @230v
but the outlet might not want to pull that 24/7
(But regular use is completely fine)
I mean thats still a full circuit with its Jan breaker but nothing too out of the ordinary
@@jonathanbuzzard6648 Ohh sorry i brainfarted until now, yeah the C14 plug is officially only rated for 10A so no more than 2300w continuous load over that
Fun fact, in the US and Canada, we don't have only 120V. Most homes also have 250V. Everyone knows the = and the =o plug but we also have a 3 prong circular one (2321 plug) which tends to run on 20A circuits, and 3 phase 4 prong circular one (3P4W plug) that runs on 50A circuits, which can push 5000W and 12500W respectively. In our homes, not workshops or something. It's weird they don't get talked about ever.
It's for heaters and AC and such, most older washers also ran on one of these. But theoretically they could be installed for any purpose if your appliance was wired for it.
@@kaldo_kaldo yeah, i saw a video from technology connections about the US electrical system. Kind of weird to have a ground point in the middle of the transformer to get "2x 120V" from your 240V supply line and then use double breakers if you need the full 240V.
Here in Germany basically all (stationary) devices that use 3phase innately are wired up directly without a plug (like literal wires into the deevice) but we also have 3 phase plugs/sockets for construction equipment etc. which can push 11kW or 22kW respectively. I'm sure there are alot bigger connectors around but those are pretty easy to find, especially the 11kW one which makes charging an EV a breeze if the on-board charger and charging brick support it.
6:53 *** ntc does have to do with temperature . As he said it limits inrush current,but it does so by having few ohms when cold, and then as current flows through it, it literally warms up and it's resistance falls few miliohms.
i love that Alex was very jank back in the day, but was more shy on camera and such. Now he is literally just going "yep we're gonna just do this and hope it works."
The alex videos with janky engineering are the absolute best videos!
Keep them coming!
The bomb has been planted.
230V Plus 16A Fuse should do the trick for this power but it is still on the limit. Nice video as allway!

Laughed so hard at that 16:00-16:30 mark where he’s having a whole panic attack. I don’t blame him one bit. Lol. I look forward to a sequel video to this. Please? Thank you so much for this video. 🙂
I’d love to see this thing on a spectrum analyzer in an EMI chamber!! I guarantee that even the base noise floor is through the roof.
Not only can it power your computer, but it will light up fluorescent bulbs up to 50 feet away.
Maybe if you put it under some highline wires it'll have some constructive interference & it'll go 110% efficiency?
Seems like it doesn't even have EMI shields so they're really not giving two shits about EMI on its electrical design lmao.
You will no longer be able to use a microphone anywhere near your computer lol. No more discord.

I'd love to see a bigclive version of this since the uk has higher capacity. Needs the HOPI for the power factor analysis.
The Hopi got replaced :(
@@IcecalGamer No, he still has the Hopi, but he got another one that is more accurate for low power loads.
the HOPI would catch fire

i done that before but making the cord longer also fix broken cord without buying new one worth it for me.
this video has a three dudes messing around in their garage vibe and i love it
I love how the "how do you get 3kW from a single power connector" question is a very north-American thing. Large parts of the world actually run 240V rather than 120V (it's also more efficient, heck, it makes EV a lot more manageable as well). 3.4kW is only 14.2Amps, usually groups are secured to 16A here. Lot of stuff such as electric hobs and car chargers even sometimes do multi-stage, such as an 11kW home car charger using 3 stages at 16A each. I'm not saying you should "just" put a 14A load on any random outlet, but honestly it's not much different from a laundry dryer or an oven. Lot of houses have 3x25A total nowadays (some still on 1x40), and you can get (but it's more pricey) 3x35 easily (more is possible but it involves a bit more work), so typically this kind of power is 'no biggy'. Is it smart? Nah. By no means. Entertaining video though, nonetheless (@Linus Tech Tips: perhaps an interesting subject as a journalistic piece: explore the challenges of power grids in electrification, I do as if 3x25A 240V is a nice thing here but honestly we struggle as well even with load balancers because our PV, our heatpumps, and our cars otherwise would... blow fuses, can NOT imagine how that would work on 120V...).
What is more interesting is how at 2:39 the label says 180-240VAC and... 10 Amps
Note, the US is 240 volts, we just split the 240 into 2 120 volt phases. An electric car charger in a US home can easily,(and regularly) be 240 volt
Quite a lot of word for missing the fact that C13 is only rated for 10 A, regardless of voltage. So even here in sensible 230 V country, you're not supposed to be getting more than 2300 W over a C13. If you want more, you need to go C19.
And a 16A breaker wont even do anything before you reach at least 18A for quite some time
@@demondoggy1825 Yeah most US households are supplied with split phase, so you can combine them to a 240v circuit. Its still a 120v system. Most of europe is running tripple phase 230v, yet its not a 400v system, even though you can run a 400v outlet on it
5:00 LOL at the switch wiring. That was done so a cheap 12vdc 1A switch could be used rather than a 240vac 15A one. Penny pinching, just like the missing components that says let the EMI be damned (probably a FCC fine waiting to happen, surprised they are not import banned).
Obviously it wouldn't be able to work with a 240V 14A switch anyway. 3450W on 240V with less than 100% efficiency.... from their claimed "90 plus" That would be 3833W, which on 240V would require a 16A fuse.
@@HappyBeezerStudios eh 15A can be overdriven an amp or 2 and never trip due to breaker manufacturing tolerances if you really push it and bin the breakers (usually 10% tolerances for cheap ones). The wiring can actually carry 2-3x rated current fine (ie insulation just getting warm, not melting) if the run is short. Most ampacity tables are for keeping voltage drop under 3% at stated amps rather than for temperature rise. Apparently the PSU won't mind if the voltage drops to as low as 180 (25% drop), but the breaker and wiring would with the amperage required to do that. It would be very difficult to run 3450W at 100% load anyway if using it for it's intended purpose (presumably a mining rack, and most mobos for those only have 8 gpu slots with each underlcocked = maybe 3kW).
Can you please explain what's wrong with the switch wiring? I only just started to study electronics and I couldn't figure it out :(
@Linus Tech Tips
The power switch turns (in back of psu) on the second psu (12v only), so that when you turn the 1st one normal gpus would have already power to display an output. However, it's a stupid why to do so. Also, it should be stated at manual to turn that switch off when not using the psu.
Can you tell us if it is worth getting or not since it has been a year and two/ three months?
Best video you guys have put out in a while. I miss the scrap yard wars, pc radiator, toothpaste thermal paste, and gpu nest with cables everywhere kinda videos. I always end up liking those the most
I think that's why Alex video's are popular. He brings the jank that we all love.
I love power supplies and actual electronics..

8:56 "The resistor is the wrong way around" Yea sure mate you almost got me but resistors don"t have polarity XD
No, they don't, but if you put the first one crossing the two, you won't have phisical space to connect the second, so you're screwed anyway 😂
This might be a stupid question, but on relation of power, would it matter if you run only the pc from a single wall outlet, or use an extention to also power your monitor etc, and does peripherals with LEDs like keyboards mice etc which gets its power from your pc, suck its performance down?
16:19 that samsung notification with the face is just so perfect
It's pretty funny how scared everyone is of the 240V. Here in Europe we have 230V at 16A on the normal lines. But there are also stronger ones with 24A. If two fan heaters with a total of 3500 W hang on a socket here, we do not worry yet.
In North America you can have 120 or 240 to anywhere. It's 240 to the home not 120. It's fused at a central point so its a different way of doing things. Also if I were to choose if I wanted corporations controlling the fuses or myself I will do it myself thanks. And no it doesn't scare me. I wired my stove which is 240 so no it doesn't scare me.
And america's 240v is split-phase so unless you bridge both sides you're only getting 120v to ground.
@@joer8854 WTF are you on about dude? A 240V MEN system has generally 3 levels of fusing for the individual supply on customer premises.
No electricity supplier is going to give you a cct without a fuse on their side so you cant take down their network.
Yes you do have a different way of doing things, that came from not knowing how to do it right when your hodgepodge of systems were put in place with no regulation.
@@mycosys 3 levels on customer premises? I know the main fuse that sits right where the cable comes through the wall, and then there's the breakers, is there another fuse in the breaker cabinet? Apart from the GFCI that's in there as well.
I think the same everytime. We can do 3680W with 230V and 16A. And if we need more we can do 3 phases with 400V and 16A / 32A / etc. And that's nothing that special.
I think I may be watching too much Jayz2cents when I expect an iFixit spot to follow an explosion
It would be interesting to see GN put this same model through their testing. I'd like to know if this is more dangerous than Gigabyte's psu's.
Same here, about both those things.
Or better yet, hardwarebusers, who can evaluate all of the protections. Because I would be very surprised if this thing had them.
Of course its worse than Gigabyte
@@xentiment6581 You say that as if Gigabyte doesn't have a tarnished reputation for a literal 50%+ failure rate on a PSU that they figured was good enough to sell
NGL i'm a little disappointed they didnt test how good a spot welder it would make, its rated for something like 300A 12V and i suspect the main protection its missing is individual rails for OCP. They titled the video 'fire hazard' and didnt test the one way it SERIOUSLY is.
1:29 On 240 volts that's actually feasible without too much issue. At 240 volts you'd be pushing somewhere around 15 amps through that connector...driving it hard, but not so much so that it melts.
3:37 and this is the part where I say i already have several times and will continue to do so. it is perfectly safe to carefully remove the cover and LOOK even if you have no knowledge on the subject as long as no power is connected. that being said, if you don't know don't touch the insides untill you know what you are doing.
It’s been a while since the last jank build from Alex, bring it on. Maybe it’ll be as dangerous as the build-a-battery video.

oooooh!!! 8:37, I think that's the same soldering iron i have, the hakio fx-888d
I totally agree with the chapter title "Alex's terrifying power meter" I'm nervous watching that and it's not me or my power system at risk.
When linus said "just engineering things" I felt it deep in my bones.
NEVER mess with power supplies!!! I did it before I knew what I was doing with PCs and nearly killed myself. I got zapped so hard it blacked my vision out and I felt the shock through my heart.
Did you gain any Superpowers? If so what are they if they are cool, I will do the same to gain those powers!
@@XhodanXeus No unfortunately no super powers. I recommend not trying it, I was stupid and didn't know about how capacitors were and it almost killed me. Idk what the wattage of the PSU was but im sure it was enough to kill me.
How long should one wait for the capacitors to discharge naturally? I have read somewhere that 15 minutes is more than enough, how long did you wait when you received that zapp?
I ask because my fountain is very old and I really want to clean the layer of dust that it probably has inside.
@@Albert-P27 Absolutely not 15 minutes. At best, maybe a day? Quite unlikely though. Most likely, a week or two to okayish voltages. Safe: 6 months or more I'd say. The time varies by huge amounts depending on the PSU design and components used.
Unless you know what you're doing, there isn't a safe way to really 'discharge' them (there is if you do know, though). There are however safe ways to clean them.
My recommendation: buy a compressed air can or use an air compressor, and blow it through the gratings outside. Try not to backdrive the fans *too* hard.
You can safely open power supplies provided you don't touch the PCBs. But even as an electrical engineer, I wouldn't trust myself to do it; too easy to forget or literally slip up (drop a screwdriver? get distracted by a call?).
Well if you're qualified to do so it's ok to open a PSU. You naturally tend to know that fat capacitors can hold a hefty charge...
In the UK you couldn't use that from a standard plug as it would exceed 13amps
>TFW, you realize that at -240V- 208V, that PSU is consuming the equivalent current of a -1,622.5W- 1,872W PSU at 110V, and 1,800W 110v units exist in standard ATX so it is certainly possible to do this with a single PSU.
