460W server power supply

The Ruth's sister DPS-460LB A is a 460W internal power supply designed for compatible server platforms. It delivers active power factor correction and a non-modular cable layout. The unit suits administrators maintaining or repairing specific rack systems.

Hot-swap build for quick replacement

A hot-swap form factor allows the module to be exchanged without powering down the chassis. Non-modular wiring keeps the loom fixed, so cable routing stays consistent across swaps. Active PFC helps maintain efficient draw on varying mains supplies.

This supply replaces the listed FRUs in X3550 and X3650 M3 servers. The jump is worth it when the original unit fails or shows unstable rails. Buyers needing higher wattage or modular cabling should look elsewhere.
