It's time to take a look at a 1200W PSU from Thermaltake, we are going to look at their biggest PSU from the Toughpower series. This PSU has four 12V rails from 20A and up so there is alot of power to be used, the question is how stable all the rails are and how loud this thing actually will be? I can only imagine how hot this thing actually will be after awhile of gaming or using the computer at load.
