MultiGPU Update: Finding the True Halo with 4-wayby Derek Wilson on February 28, 2009 11:45 PM EST

As expected, 3 and 4 way options draw tons of power even when idle.
Quad 4870 1GB CrossFire posts an amazingly high 721.8W of power drawn at the system level under 3dmark Vantage using the POM shader test. Keep in mind, again, that this test does not stress the CPU or memory in significant ways like a game would. Expect 50W to 100W of additional power drawn when the card is stressed using a game. This means that a 750W PSU can't even pretend to be enough for 4-way 4870 1GB. When running 3 and 4-way solutions, we strongly urge those interested in this kind of a setup to invest in a PSU that can deliver more than 1KW.
