    I've installed a lot of power supplies over the years and this one looks nice but feels a little on the lighter side from what I expected for a 520w. I've bought a bunch of the Insignia 400w and they actually feel like they would be heavier duty than this one. The pc I bought this for was occasionally hard rebooting on its own and this replacement did solve that issue. I went with a higher wattage on this particular pc as it had a water cooled processor and high end graphics card for CAD.

    Voltage is constant with this PSU. Runs quiet and does what it is supposed to do. No issues during install. Price is reasonable too :)

    Works great. A huge upgrade from my 300 watt power supply, and it has all the necessary hook ups my new graphics card needed. No issues.

    This Power Source Unit is what I was looking for, My OEM died after 7+ years. The connectors are the same as the old one and has just as many connectors. Stright foward replacement took about less than an hour to replace. As of today the unit is still running. Has enough power to run my Computer with all the attach hardware on it.
