550W Server Power Supply for H-P Systems

This unit is a 550 watt server power supply built to the HSTNS-PL53 specification. It matches part numbers 748949-001, 766879-001, 765423-201 and PS-2551-2C-LF. It suits administrators replacing a failed module or sparing a compatible H-P chassis.

Hot-plug redundancy in supported chassis

The supply uses a server-grade form factor that slides into a redundant power bay without tools. It draws AC from the rack PDU and delivers regulated DC to the system backplane. No external cables or adapters are required beyond the chassis slot. Builds without a matching hot-plug backplane cannot use this module.

Steady output under continuous server load

Rated at 550 watts, the module maintains its output during sustained multi-core workloads typical of database or virtualisation hosts. Thermal management relies on the chassis airflow design rather than a standalone fan curve. Systems that exceed the rated draw or lack adequate slot cooling will trigger protection shutdowns.

Questions about this item

What sustained-load limit appears first on the HSTNS-PL53 550W unit?

The 550W power ceiling is the first limit reached under continuous load.

How does the HSTNS-PL53 behave for noise, heat or power during all-day operation?

The supply delivers up to 550W continuously; thermal and acoustic performance will follow the server chassis design.

Which server model must I already own for the HSTNS-PL53 to fit and work?

This unit matches H-P part numbers 748949-001, 766879-001 and 765423-201, so the compatible server must accept one of those.
