For a gaming system that runs on about 500-550W of power, which of these Power Supplies are the best in terms of price, energy savings, and minimal RMA rate?
Other factors may include modular vs non-modular, continuous vs peak power, and railings?. Difficult to decide for myself... but yes, I'm willing to go through so much to get the best PSU in value and performance.

Also, I am running a GTX560 for my graphics card and plan to upgrade to the 600 series in the future (hopefully)without having to change the PSU.
