Compact 1U Power Supply
The Seasonic SSP-300SUG is a 300 W Flex ATX unit built for 1U rackmount chassis and small-form-factor workstations. It delivers a single +12 V rail rated at 25 A and carries 80 PLUS Gold certification at 87 % typical efficiency. Active PFC and DC-to-DC conversion keep voltage regulation tight across the 100-240 V input range.
Full Modular Build Quality
All cables detach from the housing so only the 24-pin, 4+4-pin, three SATA, one 4-pin Molex and one FDD leads you need stay inside the case. Japanese capacitors and a 40 mm double ball-bearing fan support an operating window of 0-50 °C and an MTBF beyond 100,000 hours. The 150 mm depth fits standard Flex bays without blocking adjacent slots.
Single +12 V Rail at 25 A
The entire 300 W budget sits on one +12 V rail, simplifying GPU or CPU power planning in dense builds. Over-voltage, over-power and short-circuit protection cover every output, while the 5 VSB line supplies 2 A for modern standby states. Haswell readiness confirms compatibility with low-power C-states.
