This is an excellent power supply that delivers stable to power to even high end components. Don't skimp on your power supply. This is too important a part in your PC, that you will regret later as your components wear down faster. And if you bought a prebuilt PC with a no name power supply of lower quality, this makes for a great first upgrade to your PC, which will help with present system stability, and provide you with a great future upgrade path.

Fit my tower perfectly, perfect size.

This would have worked perfectly in my desktop tower, but I was able to send mine off for warranty work, so it was not needed.
