PC Power and Cooling S61EPS 610W Continuous @ 40°C EPS12V SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply compatible with core i7

Pros: This PSU has one enormous 12v rail, and the cabling is not modular. (See other thoughts) The voltages are extremely tight under any load situation. The noise produced by this PSU is very tolerable, and it is almost silent under normal (non-gaming) loads.

Cons: This PSU is longer than others in its class. My old Lian Li case had a blowhole that was partially covered by this beast. I have since bought a NZXT Adamas, which houses this PSU very nicely. Visit pcpowercooling.com for detailed specifications on this, and all other power supplies they make.

Overall Review: If you do your research on modular cable, and multiple 12v rails, you will find that they are not that great. Underutilized rails "trap" power, while others (like the one supplying graphics cards) are over taxed. Modular cables just provide another place for a bad connection to occur. This PSU is great for anyone that wants to run a good gaming rig. My configuration is as follows. C2D 6400 OC'd, 2GB corsair mem, 8800 GTS 640MB, ASUS P5B-E,

Pros: This is a great PSU. Cool, quiet and high efficiency. Esp the powerful single rail design.

Cons: the rebate! mailed it out long time ago with everything included, but never heard a thing, can not even track the status on their site.

Overall Review: many ppl would think multi rails is better than single rail, which is totally not true. as each rail can only output no more than 20 amp, multi rails might be safer than single rail, but more power will get stucked on each rail. So, a well designed single rail is safe enough to handle most rigs and it is more energy efficient than multi rails.
