  1. It should be ok as long as you don't overclock too much. Also make sure you have all the connectors for the fans.

  3. 650w is plenty for your system, but try to get a 80 plus PSU.

    The motherboard isn't what you should worry about it's more the cpu and gpu.

  6. The video card is the major power draw in any modern computer. This will tell you how much you need for a whole system with pretty much any card.

    As you see a system with a GTX 660 needs a recommended 430 watts.

    The quality of the power supply matters though. A cheap, junk model labeled 650 watts may very well put out less power than a quality model labeled correctly at 450 watts. I would not trust an old power supply not 80 Plus certified to put out what it's rated at.

    What is the power supply make and model?

    They use Sirtec and CWT as their OEMs. Some are decent. What model is it?
