Thanks all!
750w should be enough.
+1I am running 3 7970's in one of my rigs and I'm pulling near 800W off the wall, so you should be more than ok with a 750W PSU
750w should be enough.
Thanks for the input. Any idea what watt PSU I would need for two 7950s?
you need new PSU and you should be able to run two cards, but not crossfire (with the crossfire connector between the cards).
I have an old Dell OptiPlex 755 with a Core2Duo. It has one PCIe x16 lane and one x1 lane. with a PCIe x1 to x16 adapter and sufficient power supply could I run two 7950s from this computer? Does the motherboard specifically need to have crossfire support? Would I need a dummy plug for one of the video cards?
why would you need cross fire? the cards shouldn't be connected for mining coins (no benefit from it)
no dummy plug. I believe the "latest" Catalyst drivers solved that issue (but don't quote me on that)
