my pc shuts down itself

Fwteinos Sambanhs · May 3, 2013

pc specs:
GTX 460 SE
i3 3.2GHz CPU
700W PSU
4 gigs of RAM

My pc shuts down itself after playing a game for like 15 mins. Temps all fine, checked everything while running the computer at its limits using a specific programm. When it shuts down, it wont turn on for like 20 mins or so...
I opened the case and everything worked fine, i dont thing it is the temps that are causing the problem, im in disspear.

Do you have a spare GPU you can test with? Just to start eliminating

Someone Somewhere · May 3, 2013

Which program? Was it testing the CPU, GPU, or RAM?

What PSU? Any bluescreens, or just dead?

Fwteinos Sambanhs · May 3, 2013

Rune Olsen :

no i don't....

Fwteinos Sambanhs · May 3, 2013

Someone Somewhere :

i dont know which program it was, a friend of mine did it. What i know is that it used all of the capabilities of the ram cpu and gpu. I've got an ADJ 700W PSU. No bluescreens, just dead

Someone Somewhere · May 3, 2013

Can't find anything about ADJ, so that's a bad sign. Sounds like a crap PSU that can't deliver the power it's rated at.

Do you have another PSU you can test with?

Fwteinos Sambanhs · May 3, 2013

Someone Somewhere :

unfortunately not. I have a very good friend who is a computer technincian. He built 3 same PCs and he sold me one. He didnt have any same problems with the other 2.

Someone Somewhere · May 3, 2013

Ah. Corner cutting. Is this the same friend that did the testing?

Run MSi Kombuster and IntelBurnTest at the same time, and see if it dies.

Fwteinos Sambanhs · May 3, 2013

Someone Somewhere :

whats corner cutting? Yes its the same guys that did the testing to see if it dies but it didnt when he tested it...
i will try run those 2 now

Doing something the cheap way not the good way.

Someone Somewhere :

TY! What do u suggest I do?

Fwteinos Sambanhs · May 3, 2013

Someone Somewhere :

i've had the computer for 2 years. It happened once before 5-6 months. Again before 3 months and this week it has happened about 10 times

Someone Somewhere · May 3, 2013

Sounds like failing capacitors. Unless you are really handy with a soldering iron and electronics, I suggest you get a new PSU. Antec, be-quiet, Corsair, SeaSonic, and XFX are the best. One of those in the 500W+ range would do you fine.

Unfortunately PSUs are the most overlooked part of a PC, yet one of the worst places to put a bad quality component.

Fwteinos Sambanhs · May 3, 2013

Someone Somewhere :

but, how can u be so sure its the PSU, when nothing happens( i mean the computer doesnt shut itself down while working case opened). Will 500W be enough for a system like this? Should i get some more like 600W just for more security?

Someone Somewhere · May 3, 2013

i mean the computer doesnt shut itself down while working case opened

Really? Even when running the same workloads I said above (did it fail them/shut down)? Could be the PSU overheating, or something else then.

Normally, if it's one of the other components, it will display an error, rather than shutting down immediately. Also, I'd replace ultra-cheap PSUs on principle. Some of the worst ones have no safety features, and will catch fire if overstressed. Sort of scary.

EDIT: 500W is enough for almost any single-GPU system. Your 460SE and i3 are both fairly low-power parts.

Fwteinos Sambanhs · May 3, 2013

Someone Somewhere :

so as you are saying the problem is the PSU. With 500W i hope i dont have any more unexpected shutdowns...

Rune Olsen · May 3, 2013

You can get something like this http://www.corsair.com/en/power-supply-units/cx-series-psu/cx-series-cx430m-modular-atx-power-supply-430-watt-80-plus-bronze-certified-modular-psu.html.

Will never fail you and should be sufficient

Fwteinos Sambanhs · May 3, 2013

Rune Olsen :

Would 430W be enough?

Someone Somewhere · May 3, 2013

I'm saying the problem is very likely to be your PSU, and even if it's not, that PSU is a potential fire hazard.

Fwteinos Sambanhs · May 3, 2013

Someone Somewhere :

i dont know if you are able to recognize which is better but I am in two minds. I have found 3 different PSUs to buy. Tell me which is better from your point of view.

Fwteinos Sambanhs · May 3, 2013

Someone Somewhere :

here are the 3:
XFX P1-550S-UKB9 PRO SERIES 550W PSU
SEASONIC M12II-520 BRONZE 520W
CORSAIR GS600 2013 EDITION 600W
(sorry i forgot to tell you which where the PSUs at the last message)

Rune Olsen · May 3, 2013

Your power hungry components are GPU 270W peak and that CPU will peak at 73W. The rest draws tiny amounts of power, add 10% overhead
