My PSU is 700W Vantec Ion2+, selling for rm180, not the 750W you are looking for but should work fine as well.

As for tower, i'm selling CM Cosmos II. Do take note that the power and reset switch are broken (common fault with CM cosmos II...you can do a search, problem with fan controller), so i"m selling for rm400 (ori price is 1k). This casing is not used more than two years and I always switch on either from mobo or set to turn on from keyboard input, so its not a problem for me. Other than the switches, everything else is perfectly fine, like new.
