because you are upgrading a box, do consider upping power supply to at least 650 watt for load you will be adding.
huh? my system uses about 200-250 watts actual line current running full tilt, its a core i5-3570k overclocked to 4.2ghz, with 16gb ram, 1 250GB SSD and 2 3TB HDs... it also has a cuple PCI IO cards in it, and a NVidia 640 GT video card. Its got a 450W PSU, which is plenty.
the only people that need 600W+ PSUs are running two or more high end video cards
Keep in mind that PSU nominal power is not absolute power, especially if you buy those cheep ones. Chinese 450W will give 200-300W or similar. Chieftec is another thing.
the PS I'll be using in this system is an existing PC POwer & Cooling 500W unit, which should be up to the task. (It has been running the existing system for something like 3-4 years, with a Phenom-II X2 and two HD and two optical drives, 24X7.)
