6x200GB IDE, 3ware 7056-8 + 2x18GB SCSI on a Tyan S2881 motherboard, 2GB
RAM + two 242 Opterons. 350 Watt EPS12V redundant power supply.

Mine is similar but then that was with year old hardware.

Just the capacity of the power supply is not enough to go on. Every
power supply will also list how much current they can supply at
different voltages (5V, 12V, 3.3V etc)
Your power supply also needs to be one of those EPS12V versions which
comes with a 8-pin 12V power connector. So you should get a power supply
that can supply more than 30A at 12V (not sure how much current you need
for the cpus...been a while so you're looking for something that at
least does 40A? on 12V). That is how I managed a dual Opteron + 2 SCSI
and a 3ware 7056-8 + 6 IDE disks on a 350 watt EPS12V power supply.
