ultra x3 1000watts enough?

post #1 of 9
Thread Starter 
trying to power 2x 570 gtx and 285gtx as physx. I got an offer for an X3 for a good price and was considering getting it.

It only provides 4 6/8pin connectors so i would have to use molex to pci-e for the 285gtx. Will this be safe?

I had a buddy with that PSU,, He tried to mod it to push 3 cards ( Tri-SLI 275's ) ANd it would just shut off at load.. If you use Molex to PCIe adapters tho.. I don't see why it wouldn't work.

The X3 is really a glorified 850w unit, I wouldn't do it.
Not only that, you have a Pro mobo, you'll lose bandwidth when installing a 3rd pci-e device.

I did a few bench runs for a friend running 2x 570 and my i7 930 both OCed and the X3 1000w held up just fine. As far as adding another card on top of that and not using the provided PCI-E connectors, I couldn't comment on that.

Sorry if this isn't overly useful but figured I would chime in.

It has 840w on the 12v so I'd call it a 900w.
