I need to buy a new one. I think I went overkill for my system last time since I was using a OCZ 700w power supply. I am thinking that maybe a 500-550'ish would be more then adequate still for my computer which is in my specs. Just trying to get some advice from my fellow TPU'ers to see if indeed I am correct. I am considering getting the following PSU. Corsair CMPSU-520HX 520W Or if you are selling some in the Sell/Trade/Buy section that will be ok, let me know! Also I want to go ahead and go modular since the inside of my case is a huge cluster and I am waiting for a motherboard in the mail before I start doing some good cable management. Thanks all!
