  1. 100W for the OC'd CPU, 200W for the OC'd GPU, 50W for everything else so about 350W actual load. Since PSUs are most efficient in the 40-70% range, you want to aim for a good quality PSU in the neighborhood of 550-650W.

    Is the Corsair Builder Series CX600 600W PSU 80+ Bronze a good quality cpu?
  3. That is an entry-level power supply. Corsair has traditionally been an excellent brand, but if you read some recent power supply reviews, you'll see that they are beginning to skimp on the low end stuff (not that any of it is "bad"). I actually bought that power supply and then returned it after multiple people convinced me to return it in favor of the PC Power and Cooling mkIII 600 W unit. Look up some reviews, it may not look as nice, but it is a more solid unit than the Corsair. If you are going to overclock, I would buy a quality power supply as the demands will be substantially higher.
