"The Concord MR500W comes packaged well protected and lots of features. There is a handy hole in the side of the box to verify the color the of PSU before buying it. Two user adjustable 80mm fans keep the PSU cool. At full speed, the fans are loud, but nothing like other high performance fans on the market. The power switch is oversized and very easy to find when reaching behind the computer. All the wires are fully sleeved with the exception of a small portion of the ATX connector. Included with this package is a fan controller and clear 80mm fan. The fan controller goes in an empty PCI slot and can control up to five fans. It is a common rheostat with a large heatsink attached."
