PSU problem (probably)

[BadBlack]

Hello guys Ihave being having some problems with my PC, and the issues are with the GPU, first my ASUS HD 7770 died on me slowly (began shutting down my cimputer when it was under load until it eventually didn't power the system up whatsoever I sent to RMA) but in the mean time I bought an ASUS 7850 2gb and all was perfect but 1 day ago began doing the same thing and I think there are two probabilities: 1) I have the worst luck with ASUS products

2) The PSU is being the problem here because I have checked the RAM and CPU; this is not related with twmps because I checked wit hthe 7770 the temps and were the ones that are rated to work on, also the 7850 began doing this even with 720p youtube videos while with 7770 I was able to watch youtube videos. My budget for the PSU is $100 not more.

 

SPECS:

MOBO: ASUS M5A97 evo.

CPU: fx 6100 stock.

RAM: 8 gb (4x2) kingston blu 1600mhz.
PSU: Cooler master Extreme power plus 500 Watt.

as far as i know 500w is enough to power a 6100 and 7850 so do you have spare psu laying around if not just try and rma it

I can test the GPU at a friends house that has cooler master silent pro 1000Watt, but i don't think the wattag is  the problem but teh PSU itself.

then rma the thing once you can confirm that replacing the psu fixes the problems

i run a hd4870 on a 460 watt power supply with no problem
