Enough power for a 6990?

Howdy,

I've recently bought a 6990 and am having system stability issues (eerily similar to issues I was experiencing with a crossfire 5870 setup recently). Symptoms consist of hard freezing and 3d applications crashing

Can someone critique my spec and let me know if I've got enough juice?

i7 920 @ 3.66
6GB Corsair XMS3
1x 6990
4x SATA HDD
1x Optical drive
Corsair HX 750w PSU

Thanks
 
try plugging in a different psu and see if it will work. the 750 might be faulty or you might need more juice. I'm really not sure. I think the 6990 is a relative power hog so you might be cutting it too close.
 
Yeah. Certainly could be psu. Especially since two batches of gpus had the same issue. Hmmm. Can you try it in another persons system?
 
You could always enable BIOS 1 and see if it gets worse, or unplug some of those drives for the opposite effect.

Can't answer your question, but if your PSU is still in good shape, a true 750w should be plenty for that setup. My current rig:

4 year old Seasonic M12 700W, runs constantly
HD6990
Q6600
5 SATA drives
8GB (4x2) Corsair XMS

Runs rock solid, I furmark'ed it for 12 hours immediately after install.
