Hey all, I recently bought a new video card AMD 7770 and installed it into my PC. Worked great first time I've tried this, great to play newer games for a change. I also changed PSU to 500w from 480w. I now think I wasted my money and should have gone with 600w. Some games are crashing dayz/dead space 2 with display driver crashed notification. I am wondering if I need a bigger PSU or possibly cooling system.




OS Version: Microsoft Windows 7 Service Pack 1, 64 bit
Processor: AMD FX(tm)-6120 six core processor 3.50GHz
RAM: 8 GB
Graphics Card: AMD Radeon HD 7770 Antivirus: Norton 360
PSU 500w

Thanks to everyone for their time in this even if its just to read it.

Hi! I think you CPU and stuff really isn't getting much power since its at a fairly high GHz and its six cores which is good, so I think your PC is unstable with the PSU. Maybe you should upgrade too a 700W and a good brand, OEM as well so its long lasting and doesnt let you down, also which company PSU do you have? I have an Antec 500W with my HD 6770 and no problems so far

That's not a good power supply. 500W is fine, but that PSU may be causing trouble. But Potpolima has a point, driver crashes are not the most typical result of a PSU problem. You could try reinstalling the driver.

Just an update. I tried the game on lowest settings and played for longer then usual, I felt comfortable so I upped the resolution by one setting and BSOD with atikmpag.sys within minutes, now all crashes while playing are BSOD. After this change I updated all drivers as well as BIOS but BSOD still happens when playing this game.

so look, your gpu needs 500 watts ATLEAST and your CPU and others also need, that 500 watt is not enough for your system unfortunately, upgrade to a nice psu that 600 watts and above, it would be good for quiet a while

Are you kidding? The GPU needs about 80 watts, not 500. The full system almost certainly draws less than 300 watts.
