Sorry you need at least a 1kw power supply. If you look at any of the manufacure websites they require 650w for 1 card and 1kw for 2 cards.

How can that be? The card doesn't take 350W of power.... It takes at maximum load 270W. So...

I do not see why your XIGMATEK MC NRP-MC851 850W would not power 2 4870X2 in CF. On AMD's website of recommended power supplies, they list the Xscale EP-750P3A as one of the recommended power supplies.

It has +12v1 20a, +12v2 20a, +12v3 20a, +12v4 20a. With a total wattage of 750w.

Your PSU is very comparable to that one, and it's on the recommended list.

I don't see any reason why not, but maybe TheGreatGrapeApe or someone else can provide some more insight.

certainly. did you also take into account 100% system load and an overclocked processor/slightly overclocked 4870x2's?

It's going to run, but you'll probably push it to the limit which is not good of course :non:
Go with a 1k as it leaves room for the PSU to breathe
