Pros: Totally superior to the 220w power supply in my Acer Aspire slim tower, which allows me to use my new graphics card to play games.

Cons: LOUD. But you get used to it. It's not much louder than a regular size mid-tower or bigger. Before, the system was dead silent. But it's a worthy tradeoff. Also, it didn't fit into the case, so it's sort of just hanging out the back. But it works because the computer is stationary.
