Our take on the HP P03178-B21 Power Supply Kit

The HP P03178-B21 is a 1000W hot-plug power supply kit for HPE ProLiant DL360 Gen11 and DL380 Gen11 servers. It delivers +12V at up to 83.33A through the Flex Slot bay and uses a standard C14 inlet, so it needs a C13 cord. It is a Platinum-class high-efficiency unit, which suits dense racks where power draw and heat matter. Buyers choose it to add redundancy or replace a failed module in a Gen11 chassis; it will not fit older DL360 or DL380 generations.

Pros
  • 1000W output covers fully loaded 1U and 2U Gen11 configs
  • Hot-plug design lets you swap a module without powering down
  • High-efficiency Platinum-class rating cuts waste heat

  • Flex Slot form factor fits the dedicated PSU bay
Cons

  • C13 power cord is not included
  • Single 1000W module gives no redundancy on its own
  • No management features beyond what the server's iLO reports
