Build or modify your own PC:Yes
Level of Expertise:Expert
Primary reason for building/modifying PC:Hobbiest
At its price, the Dynex 400W PSU appears to have a quality advantage over some of the economy line PSU's of the same power. It also has the convenience of purchase at retail stores. Upon opening the box, the cables seem well protected, and have a good aesthetic feel and appearance. However, this does not translate well into the internal components. Despite the packaging and the good reputation of Best Buy, this particular product fails to deliver as advertised.
While the price has decreased, the performance is still on par (or below) its peers in the economy line. This unit will work for entry level low-use, non-modified systems. If one is looking for "economy" I would recommend looking elsewhere. If one is looking for "quality", then I would steer them to Thermaltake, or Corsair for a more reliable product. It's unfortunate that the Best Buy reputation earns this sub-par component a price that misleads the consumer into believing that the quality is greater than it actually can deliver.
It is interesting to note that the 400W and 450W units have performed almost identically, despite the rating difference.
What's great about it: The appearance
What's not so great: The price and the quality.
No, I would not recommend this to a friend.

Build or modify your own PC:Yes
Level of Expertise:Average
Primary reason for building/modifying PC:Multimedia (music, movies, photos)
My power supply died and I purchased this one because my pc is so old I did not want to spend any money on it. This one seemed to be the best deal, especially given its Best Buy"rating".
It was very easy to install and fired right up but holy hard drives-is it loud. I could barely hear my old one but this one I can hear from two rooms away.
I would have given it a 5 star rating if it were even remotely quiet.
What's great about it: ease of installation
What's not so great: very very loud
No, I would not recommend this to a friend.

What's great about it: Fan is really quiet
