With 80 Plus Platinum efficiency, this power supply is suited to deployments that value efficient operation within a compact server platform.
Performance & Scalability
This 500W power supply is designed to support the power needs of compatible Gen10 servers while fitting into a redundant configuration. In environments where uptime matters, hot-plug capability helps simplify maintenance by allowing replacement without unnecessary disruption, depending on the server setup. The Platinum efficiency rating supports better power utilization, which can be beneficial in multi-server racks and growing IT environments. For organizations standardizing on HPE ProLiant Gen10 hardware, this module provides a straightforward way to maintain or restore server power functionality using a part built for the platform.
Storage Flexibility
As a power supply component, this unit contributes to the overall stability of the server platform that houses storage, applications, and virtual workloads. Its Flex Slot design is intended for compatible HPE ProLiant Gen10 systems, helping ensure the power subsystem matches the server chassis requirements. In redundant configurations, the power architecture can support continued operation while another module is serviced or replaced. That makes it a useful replacement part for keeping storage-focused servers and general-purpose workloads powered within the intended HPE environment.

About this power supply
HPE 500W Flex Slot power supply, part number 865399-001, an 80 Plus Platinum hot-plug redundant PSU for ProLiant DL360 and DL380 Gen10 servers, refurbished. Tested and stocked in Doha, delivered across Qatar within a day.
HPE part 865399-001 is the 500W Flex Slot power supply for ProLiant Gen10 servers, rated 80 Plus Platinum and built for hot-plug redundant operation in the Flex Slot bays of the DL360 Gen10 and DL380 Gen10. Flex Slot is HPE's shared power supply form factor for Gen9 and Gen10, in which the same bay takes 500W, 800W, 1600W and other ratings, so a chassis can be fitted with the wattage its configuration needs. Five hundred watts covers a modestly configured dual processor server. It is refurbished.
Buyers in Qatar use 865399-001 to replace a failed Gen10 supply, to add the second unit for redundancy, or to complete a Gen10 barebone. ServerDove keeps it in Doha stock alongside the DL360 and DL380 Gen10 chassis.

Part numbers and identification
HPE's part number is on the supply label; the Gen10 500W unit differs from the Gen9 500W part, so match the number to the generation. Buyers search for "865399-001", "HPE 500W Gen10 PSU" and "DL380 Gen10 500W Flex Slot".

Specification

Both supplies in a redundant pair must be the same wattage and efficiency grade; a 500W unit beside an 800W unit runs in a mismatched state that iLO reports. Five hundred watts suits servers with two mid-range processors and a handful of drives; a fully loaded DL380 Gen10 with high wattage processors and many drives needs the 800W part. The supply accepts 100 to 240V input.

Installation
With a second healthy supply present, replace a failed unit while the server runs: remove the cord, press the release latch, slide the old supply out, push this one in until it clicks, and reconnect the cord; the LED turns green and iLO shows two supplies. On a single supply server, shut down first. No tools are needed; a C13 cord is required and not included.
