I just bought that exact PSU, only mine was version 1 which only has 1 120mm fan in it. It can get pretty hot like that
Anyway, as much as it is a great PSU, theres only 1 thing i absolutley HATE about it. Antec states on the front, that by only plugging into the PSU, the cables you require, it will minimize clutter inside the case and improve airflow. However i found this not to be the case. The big wad of wire to the mobo is so ****ing long and if you have to use the 24-20 pin converter it lengthens it even more!! Also, the molex wires are soooo dam long (even the short ones) So all in all, my case has become severly cluttered with wires.
Dont let that put you off too
