I originally had an Enermax 600w PSU which died suddenly whist I was using it. I had it for about a year. The internal fuse appeared to have blown. I couldn't wait for the RMA turn around (which turned out to be rather quick) so I bought a new Coolermaster 620w Modular PSU with the intention of selling the Enermax on eBay. Today my Coolermaster presented with a red light, meaning its suffered a problem. But it worked this morning. My computer is sat behind a surge protector which wasn't tripped and is turned off at the wall when not in use, not to mention my server (which is in the same room) is fine. They don't appear to related and is just the latest entry into my bad luck. Luckly I haven't got around to putting the Enermax on eBay yet. Yesterday my keyboard and mouse were rendered useless because of the official wireless reciever for a 360 controller taking too much power from USB, solved by plugging it into a powered USB hub.
