  • 300W maximum output powers demanding server builds
  • Wide 100-240Vac input supports global voltage standards
  • Compact 140 x 86 x 150mm form factor fits mid-tower chassis
  • PS2/ATX multi-output design delivers flexible component compatibility

300W Server Power Supply for Supermicro PWS-305-PQ

This 300W unit replaces the Supermicro PWS-305-PQ multi-output supply in compatible mid-tower servers. It accepts 100-240Vac at 50-60Hz and draws up to 6A from the mains. The single-rail design delivers power through standard PS2 and ATX connectors for supported configurations. It fits the 140 x 86 x 150mm form factor required by the chassis.

Capacity and headroom for 300W workloads

The 300W maximum output handles typical mid-tower server loads with standard component counts. Systems demanding sustained draw above 300W or additional GPU power connectors will exceed this supply’s rating. Builds requiring redundant or hot-swap power modules cannot use this single-unit design. The fixed 140 x 86 x 150mm dimensions limit installation to cases with matching bays.

Questions about this item

Will the 140 x 86 x 150 mm form factor fit inside my existing mid-tower case that currently holds a standard ATX supply?

The unit measures 140 mm wide, 86 mm high and 150 mm deep, matching the mid-tower form factor listed for the PWS-305-PQ, so it aligns with typical ATX mounting points in mid-tower chassis.

How can I verify the 300 W output is stable after installation?

Connect a multimeter to the main rails while the system is under load; the supply should maintain its rated voltages within ATX tolerance across the 100-240 Vac, 50-60 Hz input range.
