Works as Advertised

I used this power supply to replace my 300 watt supply. I closed up the case and booted my system and it overheated after a couple of minutes. I reopened the the case and checked all of the fans and for dust. I rebooted and everything has been fine since. I have been up almost continuously for weeks. The power supply cooling fan exhausts into the PC case which I don't like, but this does not appear to be a problem.
