Proprietary 550 W unit for IBM servers

This is an IBM 94Y6668 proprietary power supply rated at 550 W. It is built as a hot-plug redundant module for System X3550 M4 and 7914 servers. The unit accepts AC input across 100-127 V and 200-240 V ranges. It carries 80 Plus Platinum efficiency certification.

Hot-plug redundant module for rack servers

The proprietary form factor fits directly into the target server chassis without adapters. Hot-plug capability allows replacement while the system remains powered. Redundant design supports N+1 configurations for continuous operation. Internal mounting secures the unit within the server enclosure.

No extra cables or software included

The module ships as a standalone power supply unit. No additional cables, mounting brackets or management software are bundled. Integration relies on the server's existing power backplane and firmware. Buyers needing spare cables or rail kits must source them separately.
