I purchased an EVGA 1600 platinum PSU a few years back. One week into using it a capacitor blew that sounded like a gunshot going off in my room. I thought my computer had blown apart. I received a free replacement from EVGA which I sold and went with an 850 instead. These things happen, but man it’s quite the experience.

[@GB-zi6qr]

About 3 years ago I built my computer. Imagine my chagrin when it didn't start. I didn't have a second PSU, but this just blew my mind. So just for S&G's I grabbed my multimeter, unplugged the power cable from the wall and computer, to ohm it out. Cables don't go bad...right? Especially when new? Low and behold I had a bad power cable fresh out of the box. Fortunately I could take a cable from another setup that's not used as much and there it is. Whew!!! Reputation as a mechanic with some knowledge SAVED!!!The best part, my son wanted to build his own computer. I had included him in building my computer.

[@watercannonscollaboration2281]

14:44 It’s unlikely that the PSU cables were mismatched, but it would be hilarious if something happened to the cable internally

[@tomr3422]

I just ran into that a couple of weeks ago, had 2 pins swapped on a 6+2 PCIE cable - took a while to figure it out.

[@gingerpenguin]

Yeah I was thinking it's worth at least checking the cables but that would require having the exact same cable spare which is probably pretty unlikely.

[@POLARTTYRTM]

I lost 3 power supplies in 6 years, luckily none of my equipment has ever gone to the grave along with the power supplies. I consider myself lucky in that case.

My psu lasted for 9 years before my cpu died. I gave away the rest + new cpu 2 years ago and it’s still working

[@liberteus]

I have a PC from 2009, still works on the same PSU, Corsair i think, 650W. I learnt to overspend on psu, because you can keep them a long time and they will save you headaches with instability or worse.

[@J_Notorious]

I’m glad for this series. Just finished up finding out why my cousin’s PC was overheating (I built the system myself and did some maintenance not long ago) Symptoms: Shut down on home-screen without running tasks and 10-15 minutes of gaming then auto shut down Checked every component, last being the CPU itself. I instantly witnessed the problem…I didn’t apply enough thermal paste! Problem solved! Did some updates, went into bios, enabled XMP, Asus performance mode, hit save and restart only to run into another problem! Debug gave me a Ram issue, cleared cmos and nothing Thankfully I had my own PC and took out a single ram stick, took out his, inserted mine and boom! Boot up! Disabled XMP, asus performance mode, saved and restarted. Everything fine with my stick Turned off and inserted his ram and boom! Boot up! All in all, your channel has saved helped my PC journey and I can’t thank you enough!

[@mikeelek9713]

About 10 years ago, I was working on a compact digital camera, and I shorted the tiny flash capacitor with my thumb. In addition to the electric shock, it burned two tiny holes into my thumb with smoke and the smell of burnt flesh. Those tiny holes eventually healed, but Greg is right. Those capacitors store an enormous amount of electricity. I have that EVGA 850 unit and so far so good after four years.

I had a similar issue a while back. I bought an EVGA 750W PSU from their B stock. Installed it in pc & system would post & boot into windows for about 30-45 seconds & then system would shut off. I wouldn't be able to reboot it until about 2 minutes later where it would repeat pattern. Contacted EVGA, absolutely no issues with RMA, got exact same model back & have had NO issues since. That's why buying from a good manufacturer is worth it.

A nice easy one for a change. Another great video Greg! It makes my day when I log on and see another great video in the series!

[@kenabi]

you have the fancy blue blobs near the top of the pcb in that psu at 14:24, those and the orangeish yellow disc to the right of them are the input protections, those will have fried to save the rest of the unit (in theory). the blue ones are Y Capacitors, and the disc things next to it should be an NTC Thermistor, and possibly a mov and an X Capacitor someplace there, too. (and hopefully a fuse as well).

[@ronny2378]

Hey greg, just wanted to ask what you do with rigs that have very simple fixes, for example like just resetting the cmos or it was just miswired because we usually never see those kind of videos, so do u record those rigs or just fix it and give it to the owner because it was a simple fix?

[@DJSolitone]

I'd first check the standby voltage rail as the unit is not responding at all. You should have a dedicated part of the PSU providing the voltage for the standby state (PSU ON / System OFF). The power rails can be totally fine. You usually have a small sub-board generating the +5VSB rail which makes the PSU "alive" once your turn the main switch on. The power rails don't turn on until you trigger them through the ATX pins from the motherboard. But because this standby rail is always connected to the mains, it is the first to absorb any spikes from the grid and potentially fail. It is also always dissipating a small amount of heat which makes it age faster than the rest of the PSU.

[@jeffreyparker9396]

Power supplies typically have a fuse on the input that should blow in a surge and there is also at least one MOV on input that might blow. The symptoms indicate a surge to me, being that the power supply acts like there is no power. Those components are fairly simple to identify and replace if you know what you are doing. Beyond the fuse and MOV, modern power supplies are typically cheap enough and complicated enough that I wouldn't likely mess with it. I typically use UPSs on my computers which will add extra protection, from much more than just surges and often are built so they don't blow up when there is a problem. All of that in addition to the fact that they provide battery backup so you can save and shutdown cleanly in case of a power outage protecting from corrupt storage.

[@BkNy02]

The same thing happened to me with my EVGA power supply! Three months after building my first PC, while I was gaming my PC just died with no warning. The weather was great, no lightning. I knew I had to start with the power supply and it came with a tester. Sure enough the power supply was dead just like in the video. Obviously it was still under warranty so I sent it back and got a replacement. But that was literally the first time a psu died on me in my lifetime. Especially a brand new one. This is not a dig at EVGA, their replacement is doing great.

[@KrastyoKrastev]

Even when the issue is found fast, i still find the video entertaining.

[@David-tm4yj]

You get what you pay for, with the Bronze rating you get good piece of mind and quality components. The higher up the scale the better the components and efficiency, it has to be said that at 120v 60Hz the current is double of my 240v 50Hz input. I also have a fuse in the plug but the RCD would trip before that worked, if the power supply was a cheap one with no rating i think it would have taken a lot more components with it as it died. Great video and you're getting nearer 1 million subscribers , not long now.

[@haosheng12]

Careful with power supplies, capacitors can carry enough charge to be lethal, and they dont always stay completely discharged either.

[@JoeH8723]

[@itscrab9124]

I built my girlfriend a pc recently actually and it had these symptoms! After basic cable checks, i decided to get a power supply tester to double check it (i bought from evga bstock so wanted to be 100% sure). After that worked i decided to double check the cpu and sure enough a bent pin! I was able to use some fine tweezers to bend it back and it now works flawlessly. Crazy to have almost a 1-1 scenario as one of gregs videos and also take the SAME exact steps to fix it! (even though the problem was different) Makes me kinda proud of myself

[@marsdeimos4301]

I once had an issue with an EVGA Supernova 750 B2 semi-modular power supply where it would turn on only some of the time and supply correct voltages on all pins, other times it would not turn on at all. I bought it second-hand for listed price of 500 CZK (equivalent to 20 USD), and the issue already showed when I went to the sellers place to and tried it out, so I got a 20% discount and took it with the risk that it might not work. When I opened it and tried to turn it on, I discovered that it would turn on more reliably if I wiggled a daughterboard slot-soldered into the PSU's main PCB (which supplies the +5VSB and contains circuitry that basically controls the standby/power). Resoldering all joints that connect the daughterboard to the main PCB seems to have fixed it, because the PSU now runs my brother-in-laws gaming PC which he uses daily, and has been going without a hitch for the last 4 or so years. Probably a cold solder joint somewhere. Happens even to the better of PSU manufacturers, and it may not cause issues right away, but after a certain amount of heat cycles. Try measuring if the PSU supplies the +5VSB when connected to mains, and if not, try bridging the COM and PSON pins, and wiggle one of the daughterboards. If it turns on, it might just need a resolder.

[@welshtechie6832]

I once had a superb Corsair PSU fully modular and the PSU cabel (UK) had a 13A fuse in it. It ruined the PSU and my Radeon 5850. In fact I think it did the Phenom board and all the components bar the memory and drives. Thankfully, by this video alone, looks like modern protection is far better!

[@jonnyk2091]

quick fix, good stuff greg

[@Nebbia_affaraccimiei]

easy and SAFE check you can do without opening the PSU is measuring resistence to GND with the multimeter of the various colors on ATX plug. if any of it is less than 10 ohms you know theres an issue inside PSU

@@andy816896 True, but it's still a good lesson and a reminder. Like Greg said, this PSU did it's job and saved the downstream components. I blew up a thousand dollar rig once because I used the PSU that came with the case. Killed the CPU, the motherboard, and a hard drive. I came home and it was just cycling on and off.

[@UpgradingAsUsual]

@@andy816896 Yes, it's not totally skimping on the PSU but just because it's EVGA does not mean it's a quality unit. It's a cheaper 550w, Bronze rated PSU. These types of units are usually made from cheaper Chinese parts and caps (capacitors). The cheaper caps are much more prone to expand with the daily in-rush current and fail within a shorter lifespan - sometimes premature. It might not be the case here but it still failed, regardless. The more expensive units use all Japanese caps and that's what you pay for.

[@patrickprafke4894]

I ordered a EVGA 750BQ from Amazon one time. Some how. We got cables from a different psu thrown in and it fried all the ssd's connected to it.

They didnt send cables back. Had to call them and remind them I needed new ones sent back. Lol

[@issacbourne5111]

I always smell a power supply. You can get a burnt smell if anything is blown. I have only had a couple that were bad and did not smell burnt. Some power supplies have a light burn smell whether bad or not. But when something burns up they have a stronger than normal burnt smell. For some it really obvious. The higher end ones have protection built in to protect the boards when they blow.

[@someguy9175]

I feel like the power supply repair could probably be worth a video of it's own, it not being valuable just adds to the appeal of just trying to go into and fixing it and the video itself would probably cover any labour costs on actually getting it working.
