Product overview
Dell lists 21HX9 as a 2400-Watts 100-240V Platinum power Supply. Mixing efficiency grades in a redundant pair is the common mistake: the pair runs, then throws a mismatch alert on every boot. This is a Platinum unit. Give us the part number already fitted and we will supply its match.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

What you get ordering this from us
Ordered by part number
The order is placed against 21HX9, not against a description of it, so there is no room for a substitution you did not agree to.
Matched to the installed unit
Send the part number already in the chassis and we supply its pair, including the efficiency grade that stops the mismatch alert.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
Is 21HX9 genuine and is the warranty intact?
Yes. It ships new in Dell packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
Will 21HX9 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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.
