HP ProLiant Gen9 550W supply

This HP HSTNS-PL53 unit delivers 550W at 12V for ProLiant Gen9 servers such as the DL180, DL160, DL120, DL80 and DL60. It accepts 100-240V input at 50-60Hz and draws 3.3A, providing 45.8A on the 12V rail. The PS-2551-2C-LF design matches part numbers 748949-001, 766879-001 and 765423-201.

Hot-plug redundant slot fit

The supply slides into the standard hot-plug bay on supported Gen9 chassis, letting you replace it without shutting down the server. Redundant pairing frees uptime for critical workloads while the common 12V output simplifies cabling inside the rack. No extra adapters are required for the listed models.

Included part-number labels

Each unit ships with the HP part-number labels 748949-001, 766879-001 and 765423-201 already applied, so asset tracking and warranty registration match vendor records immediately. The labels remove guesswork during inventory audits and speed up support calls. No separate software or firmware bundle is supplied.

Perguntas sobre este artigo

Will the 550W rating hold during continuous load on the 12V rail?

The unit delivers 550W total with a 12V output rated at 45.8A, so the full wattage is available on that single rail under sustained use.

How loud and hot does the supply get when running 24/7 in a Proliant Gen9 chassis?

The PSU uses the server’s managed fan wall; noise and exhaust temperature follow the system’s thermal profile rather than an internal fan curve.

Which HP server models accept the HSTNS-PL53 without extra brackets or cables?

It fits Proliant Gen9 DL60, DL80, DL120, DL160 and DL180 directly, using the native hot-plug slot and backplane connector.
