Hello, Currently in my current setup, I have a i7 920, 12 GB DDR3 ram, 1 GTX 260 Core 216, 1 dvd/cd burner, and a 1 TB hard drive at 7200 rpm(I think). I made the mistake of buying a PSU from a company not well-known and have been experiencing crashes. I tried a Rosewill 530W power supply and while it improved, it still crashed.
What size PSU should I look at getting? I'm leaning towards either Cosair or Cooler Master. Any particular PSU's would be welcome as well.
Antec EarthWatts EA-650 or Corsair CMPSU-650TX would be my recommendation. It is more than enough power for your setup!!
For a GTX 260 you want at least a good 500, and a little extra for aging and overclocking is smart.
Right now newegg has the Antec Earthwatts EA650 on sale for $80. and the OCZ Fatal1ty 550W for $70 minus a $25 rebate.
