H825EF-00/01 Power Supply 825W: Complete Guide for Industrial PLC Systems

What this delivery is: one Dell H825EF-00 power supply, the 825-watt unit for Dell Precision T5600/T5610 workstation towers, used, condition 95% new per our receiving record, received 2025-04-28, 2.5 kg, three-month warranty, Made in China. The same board ships under the Delta marking D825EF-01 — H825EF-00 is Dell's part number, D825EF is Delta's build number, and the two appear together on one label family, which is why listings use both.

What the part is

The H825EF-00 is Dell's 825 W hot-plug power supply for the Precision T5600 and T5610 workstation line — the silver-cased module that slides into the tower's rear PSU bay on the internal carriage, no tools needed. Input is universal 100–240 VAC; output is rated 825 W maximum continuous across the +12 V-dominated rail set that workstations with dual-GPU or high-core-count CPU loads demand. As a 95%-condition pull, the unit comes from a decommissioned workstation with cosmetic wear at the handler-touch points and clean, undamaged connector fingers. Before ordering, match your machine: T5600/T5610 take the 825 W H825EF-00/D825EF-01 build; the later T5810/T7810 towers use the H825EF-02/D825EF-02 revision, which is a different part — the two look alike on a shelf and do not cross-fit.

Why 825 W pulls sell steadily

Precision T-series towers refuse to boot with a marginal PSU long before they fail outright — the machine powers off under GPU load, and the owner replaces the supply rather than the workstation. That makes the 825 W module one of the steady movers in Dell workstation parts: every T5600/T5610 eventually needs one, Dell no longer sells them retail, and the pool of pulls is finite. Buy-once advice applies here: if your tower runs dual graphics or a 130 W-class CPU, keep the spare on the shelf — the supply is the part that dies inconveniently.
