When you see an 800W rating on a PSU, the chances that the PSU can actually manage 800W for anything but a brief spike in drain is fairly small.  Thermaltake seems to have chosen honesty, this PSU is rated at a 768W peak on the 12V rail, just a hair under what the PSU is rated for.  The efficiency stays nicely above 80% although there was some concern about the heat that it produced in certain conditions when under a full load.  Learn more about that and the technology inside this new Toughpower XT at [H]ard|OCP.
