BigBruin does a full review of SinTek's new 500W PSU.  It's got modular connectors, as in you only plug in however many wires are needed.  It has a 120mm LED fan, and you can overvolt your memory and PCIx by 5%, right on the PSU.  To see what else it can do, read the whole review.

"SinTek has a real quality unit on their hands here. The 500 Watt power supply has many great features such as the adjustable voltage rails, a 120mm adjustable fan, a digital temperature readout, and modular cabling. Having all of the cables pre-wrapped and modular makes installation a clean and easy task. All of this is wrapped together with a five year warranty."
