Two psu failures

[txnxt]

Hello,
First off thank you guys for being here, you helped me a lot just from reading through past posts. Now however I need to be a little more specific.
My pc up and died shortly after doing some gaming. After some web searching and a volt meter I found it to be psu failure. Verified by hooking up a psu from my closet, it fired things up enough to test. Installed a new psu of same make and model. PC fired up for about a day, then died the same way about twenty minutes into the same game (Legend of Grimrock if it matters. A very small game, not very gpu intensive)
My question is what might be making this happen? Here are specs:
PSU Apevia 500w model:WIN-500XSPX
MOBO GeForce 8200 Black
CPU AMD Phenom IIx4 940
GPU Radeon HD 5770 1GB

Should I try a different (bigger) psu or is something making this happen?
Thank you

You should try something by a reputable brand.
Something by Corsair, Seasonic, Antec, XFX, and many more.

The reason why is because you bought a POS psu.

Yep, amuffin is correct. Apevia makes terrible power supplies

O.K. guys, thanks. Will do some research. Still concerned why the replacement only lasted a day, though. The first one was 4 months. At least it was said to be new . I bought the comp on ebay.

With an HD 5770 you only need a quality 400 watt power supply. You can easily find a budget model from a quality brand for nearly the same price as a cheap junk brand.

Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ and Antec are all quality brands.

Here are some quality models for fairly cheap.

At $34.99 after rebate the Corsair CX430 is a very good deal.
