Product Overview

The Seasonic SSP-300SUB is a 300W Flex ATX power supply with 80 PLUS Bronze certification and efficiency of up to 85%. Its compact 81.5 x 40.5 x 150 mm body is what sets it apart from standard ATX units, and it delivers 252W on the combined +12V rails (two 18A outputs) with active PFC and cable management.

Seasonic positions this Flex ATX range for industrial use, such as workstations, standard or extended servers, and automation or communication systems. The semi-passive, temperature-controlled cooling keeps fan noise very low. Protection covers over-voltage (OVP), over-power (OLP/OPP) and short-circuit (SCP). This is the bulk version, weighing 944 grams, suited to small-form-factor builds that use Flex ATX.
