I currently had the Thermaltake TR2 600w but ive heard things about how it isnt reliable or anything. So im looking to upgrade. My current setup is a i5-2500k OC'ed to 4.0. I am also getting 2 570's to SLI, is there a power supply perferably under $75 that would work? I could go up to $100 but only if it is a stand out great one.
