Got my monitor. I find that the computer is using 250w idle and 360w max running 3dmark 2006 with intensive graphics. I cant give any figures for the Thermaltake 1000w it doesn't work. It booted for a few minutes and then failed. Very disappointed. I have asked for an RMA return number to send it back.

After my faulty Thermaltake 1000w power supply. I am now looking at the PCPower 750 quad. It does make sense to have all the power on one rail. It is a good price and gets good reviews. I see the multirail models in this category only have 18amps on each rail. Probably not enough in some cases when working the computer hard. The 1000w models also seem to be larger. I had to remove my top fan to get the Thermaltake in. It lasted five minutes and stopped working.
