    Its a power supply. If you do not overload it it will run for years. Good price for what you get.

    My desktop PC's power supply recently shorted out unexpectedly early one evening, so I headed over to my local Best Buy...Most of the pc parts such as power supplies are online only, but my local store had 2 in stock. It installed easily, and I was impressed by how little fan noise it generated! Ample power for the pc & the other peripherals attached. A good purchase if you ever need a replacement!

    It's a good PSU for the price if you aren't putting it into a heavy gaming machine. Good for everything else.

    Bought this to replace a dead power supply in a PC. This has enough connectors, without going overboard, for most basic PCs. Runs fairly quietly.

    A painless install on my PC. It's too easy to junk a mid-life PC but when it just takes a minor fix, just pop in a new power supply. Recommended by the Geek Squad,
