750W enough for CF 6950's?

post #1 of 12
Thread Starter 
I'm considering selling my 6870 and upgrading to a 6950 and then buying another 6950 in a couple months.

Would my TX750 handle the CF 6950's?
post #2 of 12
It would be fine. My Hale90 750W can run 3 of them.

Yes, you are looking at ~310 watts for the CF so that leaves you quite a bit of room.

From tomshardware, 432 watts for system total with furmark and 402 w for just cause 2

You're looking at 400W full load for OC'ed crossfired 6950s. The rest of your system is probably pulling only 150-200W at most, so you've got an extra 150-200W.

My sig rig is only using around 620w under full load (running prime95 and 3dmark11), so 650w will be fine for your rig.

You could easily run tri fire 6950's on that PSU and still be safe.

I do it on my 750. I believe you could Tr-Fire but that be pushing it.

No you can't. Not unless you're running Prime + Furmark at the same time, and even then I'm sure your PSU has a little room left over.
