Topic: How many 6970's per 1500W PS - page 2. (Read 2195 times)
I'm a little confused.. if you really meant 5970 you might want to edit the topic and OP
Buy a kill-a-watt. Every miner should have one.
I don't think you will get another 5970 though.
A 3x 5970 system draws 945W @ the wall. Overclocked they draw 1020.
I would guess 4x 5970 are drawing. ~1100W maybe 1200W overclocked. Unless you want efficiency to fall off a cliff (waste money, and more heat) you don't want to load powersupply more than 80%. 1500W @ 80% = 1200W. You likely could squeeze one more in but the PS will be running very hot and inefficient.
ya i'm pulling between 1100 to 1200wI don't think you will get another 5970 though.

i have a kill-a-watt... clone
just hopefull i guess..
i have a spare 720w powersupply....
but only has 6 pin PCIe connectors.
guess I can hook them up to the 6 Pin connectors on 2 video cards and use the 8 pin connectors from the 1500W PS in the 8 pin connectors...
thanks for the replies
I currently have 4 6970 cards to 1500w Strider power supply...
and was wondering if i could add a 5'th one.

I'd wager you're right

Ah, multi-rail fail. Appears that PSU has 8 12V rails, each capable of ~300W. So 1 card per rail (~190W each).
I'd wager you've got 1 rail dedicated to the CPU 4/8pin, 1 to the 24pin ATX, and the other 6 divvied up between peripheral connectors.
As long as you can balance the rails properly, yes. 5 6970s is going to be ~1000W.

or will it pull to much power?

and 1 harddrive.
