Ruth's sister 300W Server PSU

This Ruth's sister unit is a 300W server power supply built for 7916NP and 7916N16P systems. It delivers rated power between 251W and 300W through a 20Pin main connector, one 4P connector and eight SATA ports. Active PFC corrects the power factor across a 100-265V input range. The non-modular design keeps all cables fixed in a compact 12.5*6.4*10CM form factor.

Suits 7916NP/7916N16P replacement.

This supply suits technicians replacing the original DPS-300AB-81B or DPS-300AB-81G unit in compatible 7916NP and 7916N16P servers. It also fits POE deployments needing eight SATA drives from a single 300W source. Builders who require detachable cables for custom routing should look elsewhere, as the non-modular layout prevents cable reduction. Systems demanding 80 PLUS Bronze, Silver or Gold efficiency ratings are not served by the Other Certification level.

20Pin + 4P + 8 SATA connector layout decides fit

The single specification that determines compatibility is the fixed connector set: one 20Pin main, one 4P auxiliary and eight SATA power plugs. If the target backplane or drive cage uses this exact arrangement, the unit will connect directly. Any chassis needing a 24Pin ATX main connector, additional 6P or 8P PCIe plugs, or a different SATA count cannot use this supply without adapters that are not included.

Domande su questo articolo

Which server chassis models accept the DPS-300AB-81B/G 20-pin connector?

This unit is built for the 7916NP and 7916N16P platforms that use a 20-pin main power connector.

Can the eight SATA connectors power drives in an older backplane that expects standard 5 V and 12 V rails?

Yes, each SATA connector delivers the standard 5 V and 12 V rails used by legacy drive backplanes.

How can I confirm the PSU is delivering power after installation?

The unit powers on when the server front-panel switch is pressed; drive LEDs and fan spin-up show the 300 W output is active.
