Summary: Old computer power supply died. Bought this with some trepidation - didn't know how easy swapping them would be: everything lined-up, all cables and connectors matched and, when I pushed the button, everything worked! Very quiet fan, very VERY stable power (using SpeedFan to monitor Voltage) and low to no heat coming off the unit. Powering 3 hard drives, a graphics card, 2 Optical drives and 2 large case fans and no hiccups after nearly a month of operation. Recommended!
Summary: easy install. strong product. i had to buy an extension for one of the 4 pin molex power plugs to reach the mobo graphics extra power port because it would reach when it was plugged into 2 drives. other than that, highly reccomend! if you intend to crossfire any radeon cards it will be underpowered.
Summary: I've purchased several power supplies in the past and bought this one to replace a 300w in a new computer I purchased which I upgraded with another HD, memory, dvd and video card which required more wattage. There is absolutely no noise issue that I can discern, it is very quite and well worth the price.
