Well the full system would be:
CASE - PC Thermaltake VN10006W2N LEVEL 10 GT Snow Edition
POWER - Corsair 650W TX PSU-650TXV2EU
MOTHERBOARD - Asrock s1155 Z68 PRO3
PROCESSOR - Intel 2600K
HDD - Samsung 256GB MZ-7PC256N SSD
MEMORY - Kit Corsair Vengeance 2x4GB 1600Mhz CMZ8GX3M2A1600C9 DDR3
VIDEO - Gigabyte GV-N590D5-3GD-B - GTX590 3GB Nvidia PCIe
Except for - USB mouse, USB keyboard, USB DVD-RW - other stuff connected to it has its own power supply and I don't plan on adding any other PCI cards or w/e.
So won't it be enough then?
