This 350 watt power supply upgrade is a retrofit design to replace a large number of odd-shaped Compaq power supplies. Compaq power supply models PDP-121, PDP-121P, 277979-001, 308615-001, 308437-001 are just a few of the models that are replaced by this power supply. To accomplish this task we had to manufacture a bracket that would mount cleanly in your computer case while also holding a specialized power supply that is electrically compatible with your original compaq power supply. While building this power supply we went ahead and made it 300 watts to give you an extra kick of power.
