SSP-300SUB is a 300W 1U Flex ATX power supply. As one of Seasonic's latest editions SSP-300SUB is the little brother of the more efficient established SSP-300SUG. Being Modular, SSP-300SUB is particularly well suited to applications where a custom cabling is required. This is a great benefit for reducing inventory whilst having the flexibility to have exactly the cabling and connectors required to suit the particular application.

A special feature of SSP-300SUB is its fan controller, seen on many other Seasonic power supplies fan noise is minimised by the fan being switched off at low loads.
