OP, if this is for your system, you don't need anywhere near 600 watts. Your GPU takes 150 watts, your CPU is rated at 65 watts. A 400 watt unit will work just fine. That is, a quality 400 watt PSU. And I'm with everyone else. Buy Seasonic if you can. FSP is not junk. I run a 95 watt CPU with a 150 watt GPU on an Antec Earthwatts 430 without a problem.
