Product overview
This is the HPE 800-Watts redundant power Supply for ProLiant, order code 865438-B21. Mixing efficiency grades in a redundant pair is the common mistake: the pair runs, then throws a mismatch alert on every boot. Give us the part number already fitted and we will supply its match.
We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.

Questions buyers ask about this part
- Is 865438-B21 genuine and is the warranty intact?
- Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
- Will 865438-B21 work in my server?
- Send the server model and the part number of the supply already fitted. In a redundant pair both units have to match on wattage and efficiency grade, or the chassis alerts on every boot.
- Do you accept purchase orders and quote at volume?
- Yes — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

Specifying a system, not just the part?
An accelerated node draws far more than a general-purpose server, so power is sized with the build rather than assumed from the chassis.
