Does my PC crash cause of PSU?

[fanazatas38]

Hello, my PC crashed without a message on the monitor (I meant it wasn't BSoD), just everything on the screen has gone. Also lights of my keyboard and mouse was gone too. And after 5-7 seconds the case tried to boot but before the beep sound it stopped again. It was like somebody pulled the power cable off. What is the problem here?

My PC specs:

CPU: INTEL CORE I7 7700K
MOBO: ASUS B250G STRIX
GPU: MSI GTX 1060 GAMING X
RAM: 2X4GB DDR4
HDD: SEAGATE 1TB 7200RPM
SSD: SANDISK 120 GB
CASE: Thermaltake Commander MS-I
PSU: (the case's standard psu) Thermaltake LP-700AL2NH 700W

What happens when you try to power it up now?

It does sound like it could be the PSU.

I'm typing these messages from the PC right now, it's working fine for 30mins.

Actually the problem is still ongoing. Yesterday, it turned off and tried to turn on again 2-3 times. After that it stopped getting the power automatically. I pushed the power button by hand and it just worked for 0.5 seconds. An then I decided to turn psu off and wait. After 1-1,5 hours, I turned the psu on and tried to boot the case again. Everything was fine. But it stayed fine for 2-2,5 hours. And then everything repeated.

It looks like the case running as the time it stayed off. Does it charge itself when it's not running and the psu turned is off? That sounds... I dont know. What should I do?

It's hard to say for sure that the power supply is the cause of the problem, but it's hard to diagnose this kind of problem without the complicating factor of a *really* low-end power supply in the mix. That it's an included power supply in a $45 case is a pretty big red flag as there are only a couple of highly recommendable budget-line PSUs (lower-wattage recent Corsair CX and SeaSonic S12/M12) that are available by themselves for that price.

In this case, it's a Thermaltake Litepower. And not one of the Channel Well or FSP Thermaltake Litepowers that are simply mediocre. This is a dreadful one, an ancient PSU made by Deer/Solytech, one of the most notorious purveyors of PSU-shaped junk cubes. It's the kind of PSU you'd like to see a special forces team secretly install in the PCs of ISIS leadership.

So, you meant that I should buy a new one in any case, I guess?

Yup. Definitely the first thing I would do. If it fixes the problem, then you're all set. If it doesn't, you've ruled out the power supply as the issue and have a $1000 PC that you don't have to worry about literally going up in smoke if you leave it one when you're not at home.

I agree with the above.

Also....the fact that it powers up after you let it sit....this could be due to the PSU cooling down.

 

[fanazatas38]

So which PSU can you recommend me to buy here guys?

 

[fanazatas38]

Would that be fine for me?
"CORSAIR TX Series TX550M 550W 80+ Gold Modular Power Supply"
and what about that?
"SEASONIC SEA-S12II-620 620W 80 Plus Bronze Powe Supply"
thanks in advance.

I edited the comment at the exact time you replied it... What about the Seasonic? Which one to prefer here?

Thanks.

In this case, the Corsair. That SeaSonic was a nice PSU in its heyday, but the S12/M12 series is showing its age, with the older, group-regulation that designs have moved on from.

- Most of the time it's either GPU internals or CPU/vrms overheating, or unstable insidious slight overclock in the bios of the ram or improper ram timings:
- Any screenshot of your HWMONITOR in idle and under load with GP, CPU clocks, temps, usage and motherboard temps and fans, thanks
- you could help PSU stay relatively cool by installing a high RPM 120mm fan - which you would increase the speed- at bottom of the drive cage blowing air on PSU and GPU fans from underneath, it really makes a difference.
- Resetting Bios to default would disable any non optimized settings.
- Use Hwmonitor to keep an eye on your CPU temps and fan speed , same for GPU and adjust fan curve accordingly with proper software .

Actually I bought and set up a new power supply based on the above replies. And its looking fine right now. If the problem repeats, then I will be looking to your solution ways. Thank you anyways.

Great outcome, thanks for the feedback.

Great to know. Hopefully the problem is solved and now your PC is better than it was before the new PSU!
