Just a quick look at the picture on newegg shows a fairly basic power supply, and Cooler Master is not known for using quality power supplies.
I see standard 4-pin Molex and floppy connectors, and a string of SATA style power connectors. The reviews from owners list that it comes with a single 6pin PCIe power connector. I wouldn't call this a 500W power supply. More like a 280W or 350W.
