Hello guys :)

I've recently built a nice rig consisting of the following

Coolermaster 650W GX
2 Gigabyte 7950 ( very slightly overclocked ) ( I've changed the cooler to arctic accelero 7970 too on both )
10GB ram
Cheapest CPU I could find.

I use the computer for a specific task which requires full load on both graphic cards. Now whenever I start putting full load on both graphic cards everything works fine for about 5-10 minutes, then suddenly the screen drops dead ( "no signal" sign coming up).

At this point i cannot move mouse to get screen back up or send commands. However all the fans are still running and the computer is alive.

Is it possible the PSU that is too weak or is it maybe another problem? I suspect this as running 1 graphic card on full load works just fine.


Any help would be greatly appreciated :)

So coolermaster really sucks. Switched over everything to a new pro XFX 650 W and it works just smooth.

Thank you all for your help.

And yes I'm mining litecoin :)
