Well the bad news is that it's a Coolermaster. The good news is that model is one of about 2 that are decent. It's made by FSP though and that's generally not a good thing. Seems like they got that model right though.

I personally avoid their products as a great many of their power supplies are labled way over what they can actually produce.
