I built a system recently, slapping in a Radeo HD4870, and I'm having a lot of problems with running games @ 1440*900, I think it's down to my PSU?
Some games I play, about 1 minute in (on lowest gfx) will crash, with the screen's graphics going all distorted in little squares all over the screen, and I'll just have to turn the pc off manually.
Other games running full screen and lowest gfx settings will just lag out about eveyr 1 minute for a few seconds, before continuing, but will eventually crash.
I'm usually an old
500w PSU, so I think that's my problem (as this gfx card is a power GUZZLER).
So if I were to buy a CorsAir HX620w, would that suffice?http://www.amazon.co.uk/Corsair-EPS12V-Modular-Version-CMPSU-620HXUK/dp/B000RWCIDI/ref=sr_1_19?ie=UTF8&s=electronics&qid=1221772830&sr=1-19
