300W Server Power Supply for 7916NP

This 300W server power supply is built for the 7916NP and 7916N16P platforms. It delivers a rated output of 300W with active power factor correction across a 100-265V input range. The unit uses a non-modular design with a 20-pin main connector, a 4-pin connector and eight SATA connectors included.

Suited for compatible server maintenance

This unit suits technicians replacing a failed PSU in a 7916NP or 7916N16P chassis where the original connector layout is required. It is not for builders who need modular cabling, higher wattage headroom or standard ATX form-factor dimensions for a custom build.

20-pin main connector with eight SATA ports

The single specification that decides fit is the 20-pin main connector paired with eight SATA power ports and one 4-pin connector. Verify that your server backplane and drive count match this exact connector arrangement before purchasing.
