Good!
Make sure it's a good brand. Like hard drives or RAM, the power supply is no place to try and cut corners.
I had a very old computer that I hadn't started in some years. I plugged it in just to see what would happen, and got a bang like a cherry bomb from inside. Thought my heart would give out.
One of the big capacitors had let go. The end blew open. Looking at the other ones, I saw scoring in the end caps. Holy crap, they're DESIGNED to safely explode! Who knew?
