Product overview
Dell lists D850EF-01 as an 850W modular power Supply (for alienware aurora R5/R6/R7/R8/Area-51 R4/R5 desktops). 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.
Priced per unit, with tiered pricing at quantity — send the number you need and we will come back with the banded price.

Questions buyers ask about this part
- Is D850EF-01 genuine and is the warranty intact?

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.
