Cooler Master does dual Quad-SLI on Single 1100W PSU
 

Cooler Master had a demo up and running of two systems powered by a single power supply; and in all fairness, Foxconn had one of four systems powered by one power supply, but the difference between the two is that Cooler Master had a two quad-SLI system.

Both setups were looping 3DMark06 and seemed to be running just fine using a single 1100W UWP PSU, which isn't a bad feat in itself. What makes it even more interesting is that both setups were using quad-core Intel Q9450 processors, Asus Striker II Formula motherboards, a Raptor hard drive and 2GB of memory.

of course, what I've been saying for years now, any none-extreme rig will do fine with a 500W PSU, and in most cases that is even overkill:)

you almost made me think you didn't know what you were talking about :-p . 500W is indeed overkill in most cases, a normal office PC has enough with a 300W PSU, midrange gaming rigs should do fine with 400W (if it's a quality PSU of course).
