Antec Quattro 850w! Enough for 2x 9800gx2 cards?

post #1 of 6
Thread Starter 
Gidday!
Just bought a second-hand Antec Quattro 850 on the internet for a reasonable price (please don't tell me not to buy anything else, as I have bought this already.)
I was just wondering if anyone could shed some light on wether this PSU will be able to run my system at 4.0ghz overclock and drive 2x asus 9800gx2 cards.

Also. does anybody know how these cards preform in quad sli in BF3. hoping for High-ish gfx settings and like 50ish fps?
will be playing mostly Project Reality for Battlefield 2.


Thankyou!

Yes, it will easily run those cards and overclock.

That psu should be able to run 3 of those cards with no problems.The Gx2 is a power hungry card but not enough to need more than what you have.

BTW running 3 of them would be for folding,etc.

Okeydokey. apparently it is not powerful enough or there is some other problem. I have 1 card connected to the 12v1 rail which is non modular. That works perfectly and both my cards work with that (2x 6+2pin) BUT! whenever I try to run 2 cards or just one card on the 12v2,12v3,any other rails, it wont boot. These still work fine to power my 2hdd and Bluray. I have tried absolutely every combination, even tried to mix and match rails. E.g 12v1 and 12v2 half on each card. Am i setting it up wrongly. I can take a photo if needed.
Are my 12v2,3,4 rails broken/damaged?? or am I just doing things wrong.
So when i plug in a 6 or 8 pin plug from any rail other than 12v1 my system wont boot.
