180W server power supply

The Graviton HK280-86FP FSP180-50PLV is a non-modular 180W server power supply designed for specific Lenovo i-series hosts including i2656, ir358, ir608 and i2676. It uses a 20-pin interface with active PFC and operates on 200-264V input voltage. This unit serves as a direct replacement for spare parts 36001822 and 36001754.

Capacity and headroom

The 180W output delivers power through two SATA ports, two D-type bus connectors and a 4-pin CPU connector. It has no 12V graphics card pins so it cannot support dedicated GPUs. The supply fits systems requiring this exact wattage and connector layout but runs out of headroom for any add-in cards needing auxiliary power.

20-pin interface constraint

The 20-pin interface type is the single specification that decides compatibility. Only servers and desktops listed in the compatible models — such as i1345, i1355, i1360 mainframe, r358 and r608 — can accept this connector. Builders needing a different pin count or modular cabling must choose another unit.

Questions about this item

Will the 20-pin interface and 4-pin CPU connector fit the i2656 server I already run?

The unit uses a 20-pin main connector and a 4-pin CPU power plug, matching the i2656 and the other listed Lenovo i-series hosts.

How can I confirm the 180 W supply is delivering stable power once installed?

Check that the server posts without voltage warnings and that the two SATA drives spin up reliably under load.

Does the non-modular cable set include the two SATA leads, or must I source them separately?

The fixed harness already provides two SATA power connectors; no extra cables are required for those drives.
