hello i am going to buy new parts for my pc and i want to ask if my CoolerMaster real power 620W power supply will work whit thease parts also the power supply has three +12V rails whit 19 amprange on them,and on +3.3V rails it has 25 amps and on the +5V it has 25 amps.
Intel Core I7 930 2.8GHZ 8MB LVL 3 Cache
XFX GeForce 260GTX Core 216 one video card.
Corsair 3X2GB 1600MHZ Memorys total (6)GB,Tri Channel,DIMM CL8 KIT.
Not counting things like HDDs, fans, USB devices and such, I'm getting just over 300W calculated. Even factoring in 20% increase over that + those extras (which is what I tend to do), you should be totally fine.
