This is one of the few power supplies with more than 10 amps that I could find. I used it in my garage to power a car stereo I had installed in one of my closets (I'm tired of buying new stereo receivers every time lightning strikes). If there is a downside, it would be that the fan is a bit noisy. But it works great. This is an update on my original review: Having owned it since June, I thought maybe it wasn't worth the money after all. I only use it once or twice a month while working in my garage and since yesterday it has stopped working.
