Hey all,
I recently just got a new computer built for me, it has 2gb of overclocked RAM, an overclocked duel core 4400 + 2.31Ghz AMD CPU, and an Nvidia 250 series graphics card. The PSU is 650w, but i'm sceptical of it, since i got it very cheap for the wattage. Link:



Now the problem is: When I am doing normal day to day activities, web browsing, playing music, going on msn, etc the computer works fine, but when I try to go on games, such as TF2 and L4D, it functions well for a while, but then proceeds to shut down, no warning, no blue screen, it's just as if someone has pushed in the power button, I have to unplug everything, leave it for a few seconds, and then plug it back in again.


any idea of what the problem may be?

thanks,


Joe

can you give us how many amps each rail is capable of
ie 12V+, 12A
this can be located on the PSU
secondly remove the competitor. read the FAQs

the same problem happened to an old PC of mine, it turned out the PSU wasnt powerful enough to power the machine

We need the amount of amps available on the rails. Should be on a sticker on the PSU.

And remove the link please.
 
I'm not sure man, ive taken the side pannel off and looked at the sticker, the only thing that remotely resembles what you said was 12v (and a subscript 1) + 12v (and a subscript 2). Is it not safe to assume that because the psu is cheap and unknown, and I had the same problems as you with a dodgey psu, that the problem is the psu?
 
your should just prime it or OCCT GPU test it :D it would tell you a lot but the heat sink on the CPU may have came loose in transition:( hence why the instant shutdown the motherboards overheating protection will be shutting down your to prevent CPU damage if the heat sink not seated securely
 
stick a large house fan pointing towards your open case, specifically your graphics card - then try. If it works then you probably have a problemo with your case cooling or even the cooling on the graphics card.
 
Sounds like a faulty GPU. I had the same thing with my old ''3850''. After that i used an old 7800GT i had. everything was fine. As you can see that was a long time ago, Good luck with it.
 
Faulty GPU wouldn't cause it to power down instantly.

The problems you're describing are classic signs of an underpowered PSU. What make is the PSU?
