    It made for a fast, inexpensive replacement for a failed PSU. Minus 1-star due to the fan being noisier than my old PSU that had 2 fans. Also, it lacks an on/off switch.

    Power supply installed by geek squad person. He got the right one for my computer, put it in and tested it while I waited. I am happy both with the power supply and with the help received.

    Had the Geek Squad work on my grandsons computer to speed it up and improve the graphics this power boost assisted greatly in making that happen. Outstanding work by the Squad.

    Worked well. Setup was a breeze. Purchased as open box but should have waited on sale on name brand models that have longer warranties. This only has 1 year.

    Worked perfectly in a new computer I built. I would have rated it higher if it had a switch on the back. That's the only ding in the rating I can think of.

    This power supply works fine but it was too big to fit my PC case so it has to sit on the floor beside it.

    Works great, great amount of power, only drawback is that the 8 pin cable to the motherboard is often too sorry if mounted at the bottom of the motherboard.

    It has relatively good output, lots of different connectors are available. Need more power for gaming but when you are in a bind, go for it.
