It's not the motherboard that is the issue...it's the videocards that draw so much. Think about it....2 BFG 6800UOC's....
Um, i dunno for sure, but...

Older ATX (1.0) power supplies with 20-pin main power connector do only have one 12V line. Such a high charge on one line can damage a PSU over the time. New ATX 2.0 PSUs, featuring a 24-pin power connector have two 12V lines, so the load is split to two lines.

ASUS recommends a 450Watts or even better PSU, to drive a SLI system with Athlon FX 55 and GeForce 6800 Ultra - which means at least 281 Watts just for these items!

note it did not say two ultra's....just one.

According to information provided by MSI, using a 20-pin ATX power cable is possible however as long as at least 18A are provided along with the 12V power supply. These reveals are in opposite of what we heard from ASUS, which claim that a SLI system needs much more power than that. We'll have a closer look at that and report our findings.
