What PSU should I buy for my new pc? I got i7 4770k, Maximus VI Impact, Corsair Vengeance Pro DDR3 1866MHz, Corsair Force Series GS SATA III SSD 2.5 (180GB), Asus GeForce GTX 760 DC2T, 2048 MB. My case is a red Bitfenix Prodigy, so just to match the color I am thinking to buy an EVGA Supernova NEX750G but I dont know if it's the right choice.
