    These really are great power supplies. They have a good weight and I've installed at least a dozen of them over the past couple years and haven't had one fail yet. Can't beat the quality for the price and they're easy to obtain when you need one on a whim.

    This was a replacement for a computer running windows 2000 with "ide" drives. Not enough of proper connectors for the drives but then this is basically a legacy computer now and I understand every dinosaur cannot be supported. It got things back up and running.

    Works great. I purchased this power supply when my son's gaming computer went out. It was easy install, a good value and has turned out to be reliable.

    My computer modem wouldn't turn on, so I was advised to buy one of these to replace the old one. I made sure to see where the wiring was on the old one before I replaced it but once I did my computer is working as good as new with no issues.

    My power supply died so the Geek Squad changed it right there in front of me, in and out in 30 minutes. More power than I had before and at a very affordable price.

    This PSU does what it supposed to. I bought it for my step son's computer because the old one died. Installation was quick and simple. Most importantly all of the cords had enough length to reach the connectors on the motherboard.

    My computer was randomly shutting down. My oldest son (thank goodness for knowledgeable sons) diagnosed the problem as a defective power supply and Best Buy was the only store to have this item in stock. For less than $40.00, I have a "brand new" computer.

    My desktop computer had completely stopped working. I put off repairing it, fearing that it would be a costly repair. I finally took it in to the Geek Squad and this was the piece of equipment that needed to be replaced. An inexpensive and easy repair!!

    I was a bit concerned when buying this power supply; it was MUCH cheaper than the name-brand models and it wasn't clear that it would have all the connectors I need for my older equipment. Well, it works just fine. No glitches, crashes, brown-outs.

    It is metal box with a fan, wires, and electrical components. It can power a motherboard with up to 24 pins on the connector. It can also power sata drives and old school drives. It doesn't work well underwater, it makes you tingle a little. The only downside is the 4 pin CPU connector. The best thing is that it doesn't smoke when it is on.
