Each motherboard and cpu has it's own psu and 2 of the 3 quads have xclio goodpower 500w psu's while one has an antec earthwatt 380. They all have G0 cpu's and are clocked at the same speed, but it appeared that the system running with the earthwatt cpu was actually only using about 120w while the other two systems were using just over 155w, I will be testing this in more detail at some point this summer, but I was left with the impression that I could save 30w per system just by switching from the xclio goodpowers to the earthwatt psu's.

I think it is mostly because the systems aren't drawing enough power to be in the efficiency envelope on the 500w psu's, they are all 80+ certified, but I read good things about the earthwatt 380's so when I ordered my last node I went with one of them and now I'm wishing I had done the same for all four nodes.

And that is correct, the entire rack with 3 quad core cpus, a dual core cpu, 15" lcd monitor, 8 port 1000mb switch, 1 hard drive and one pci videocard pulls 570w.
