Even this is entertaining for us, come on guys, don't use flawed technical arguments. I said in a previous post that if shutting down half the memory reduced the power from 1000W to 900W, shutting down the rest won't reduce it by just another 100W but more, because idle memory consumes much less than active memory. Other than that, let's assume a system with 4 CPU's, a server motherboard, a few drives and a few fans consume 800W. A SCSI drive takes up to 20W, a high-power fan up to 15W, substract a few of each from the 800, substract a few more W for the various motherboard integrated stuff, then multiply everything with 0.9 (wich is a fair efficiency figure for the CPU PWM circuit), and you might end up just where you should.

On the other hand, in the testing done by us and also other hardware review websites, i haven't seen figures for the power consumption that would be far off the rated TDP.
