Time to kill some watts

I figured if I was going to run a powerful computer that requires new electrical wiring, I'd have to find out just how much energy I'm using.

So I got a Kill-A-Watt.

And I have learned some things.

The Xeon LNXI compute nodes consume 130W in "waiting on a shout back from the master node with the rest of my BIOS" mode. I don't know what kind of drain this entails, but I do recall that a computer in BIOS mode is often consuming full power to do nothing.

The Opteron LNXI nodes consume 210W in the same mode.
