Yea, rambo dont over simply things, Corsiar doesn't make PSUs, they are are all made by seasonic, Delta, and Channelwell (corsair anyways).

For gaming, Dont bother with an i7 maynard, the HT does absolutely nothing, and the chip does not clock higher then an i5.

And get some more info on that PSU, I assume the power cord still works look at getting a antec neo-eco possibly I can look for some deals later on some good PSUs.
