New power supply

[Accivatti]

Hi, I just bought a new power supply (ultra x4 1050w) plugged everything in and absolutely nothing happened. No power to mb at all. I plug in my old one and everything was fine. Could it just be faulty?

Ultra has a particularly bad reputation for PSU quality. I'd return it for a quality PSU. Your system would run well on a good 750W PSU, such as one made by Seasonic (their own, XFX, some Antec) or Super Flower (Rosewill Capstone, Kingwin Lazer, EVGA B2 & G2).
