Server Power Supply Kit

The HP 605923-B21 is a 460W Common Slot Platinum hot-plug power supply kit with backplane. It is built for HP ProLiant servers that use the Common Slot form factor. The unit delivers single 460W output for rack-mounted workloads. Buyers needing redundant power configurations cannot use this single-unit kit.

Platinum Efficiency at 94%

The supply carries 80Plus Platinum certification and operates at 94% typical efficiency across the 100-240V input range. This high efficiency reduces waste heat and operating cost in compatible chassis. The 50/60Hz input frequency range suits global mains standards. Servers lacking the Common Slot backplane cannot accept this module.

460W Maximum Power Rating

The 460W maximum power rating is the single specification that determines whether this unit can support a given server configuration. Total component draw must stay within this limit for stable operation. The ProLiant DL160 G6 is a validated platform for this supply. Systems requiring higher wattage must select a different power supply.
