Is my PSU sufficient for my rig actually i was going for cooler master xtreme power 500 W but i was recommended Cooler Master GX-550W Power Supply.
I wouldnt have gotten a Coolermaster unit, all of their ones in that power range are pretty crappy right now, if you havent already bought it dont get the GX 550 it has the same ripple problems as its larger brothers, over about 60% load ripple goes out of spec on the 3.3V rail, get a good unit like an Antec TP-550, Corsair 550VX, or Seasonic S12II 520W
