Remember PC power supplies usually have a MINIMUM draw requirement in order to regulate... (usually around 10% of rated watts)... I found that out when I used a 150W AT power supply to run the coin reject lamps (#45s) and fans (80mm and 60mm) in my MAME arcade cabinet... originally I wasn't drawing enough to regulate the PS... was swinging between 3v and 45v on the 12v line. Can always chuck a resistor in to get the minimum if necessary... course, that's just burning off power for heat, but...
