Worlds Smallest Power Supply Page: 1
It uses (patent pending) HyperWatt technology in order to be able to put out an impressive 120W from its tiny footprint. No enclosure or cooling is needed. Part of the reason why it is so small is because it is a DC-to-DC power supply. This means that it will have to be used with an external AC-to-DC power converter as do almost all Mini-ITX power supplies.
