The HPE P03178-B21 is a 1000W Flex Slot power supply option for HPE ProLiant Gen10 and Gen10 Plus servers, positioned for configurations that sit between the mainstream 800W class and the heavyweight 1600W units. Dense storage builds, higher-TDP processors and expansion-heavy 2U servers all benefit from the extra margin a 1000W supply provides, without the cost or circuit sizing considerations of a 1600W unit.
As a B21 option part, P03178-B21 is the orderable kit format that integrators and IT teams specify when configuring or upgrading Gen10-era servers. It installs into the Flex Slot power bay in the usual tool-free manner and supports hot plug operation, so adding it as a second supply for redundancy, or exchanging a failed unit in a redundant pair, is done without taking the server offline. Efficient power conversion keeps operating costs contained through the long service life these servers typically deliver.
Procurement teams often encounter this part when a Gen10 Plus deployment specifies 1000W supplies from the factory, or when an existing server needs more power headroom after a processor or storage upgrade. The equivalent spare number seen on the unit itself is P44412-001, which we also stock, so whichever number your documentation or PSU label shows, the correct part is available. If in doubt, send us your server product number and our team will confirm fit for the HPE P03178-B21 before you order.
Euroland IT Store is a trusted UK supplier of new and refurbished enterprise hardware and a comprehensive range of HPE parts, and we hold the P03178-B21 power supply in UK stock with both condition options. Refurbished units are load-tested and warranted. Contact us for a fast quote, reseller pricing or delivery timescales for urgent replacements.
Specifying 1000W buys certainty. Upgrades that would push an 800W configuration close to its limit, extra drives, faster processors, additional cards, fit comfortably within the envelope of the P03178-B21, so the server you buy or upgrade today will not need its power revisited next year. That protects both budget and change-control time. Field engineers matching the label on a failed unit should look at the equivalent HPE P44412-001 1000W power supply, while the mainstream HPE 865412-102 800W Flex Slot power supply remains the right choice for standard dual-CPU builds.
Redundancy remains the operational core of the value: with two hot plug units fitted, a supply failure is invisible to users, and the replacement goes in with the server live. Efficient conversion trims electricity and cooling costs across continuous operation, a benefit that scales with every server in the rack. Euroland IT Store supports both sides of the buying decision, new P03178-B21 stock for production-critical systems and tested refurbished units for spares, labs and cost-sensitive projects, all held in the UK for fast dispatch. Our server power supply category lists every wattage and part number we hold, and pre-sales compatibility checks mean the part that arrives is the part that fits, first time.
