games crash psu R9 280x problem

[alichowdry]

Hi, I today purchased a r9 280x to put in my system, it replaced a burnt 7950, I am worried because I read on the box that the minimum requirement for psu is 750 watt and mine is only a cx600, also all my games keep crashing. Will a reinstall of windows fix this with updated drivers? Or shall I take the card back and swap it for a less hungry one?

Thanks

While not great, the CX600 should power a typical system with a 280X. You might want to do some more digging into the crashes.

ok i have the same exact card the windforce version comes with clock speed of 1000mhz for gpu and 1375mhz for ram and im gonna say this once it is a defective product even with a gigabyte board it crashes randomly especially when playing call od duty advanced warfare and i realised there isn't much solutions to this problem online...i fortunately have solved my problem and want to share it...what you have to do is use OC guru 2 by gigabyte and down clock the voltage to 1.11v from 1.17v that's how i got mine to stop crashing hope it works for you
