DPS-500ab-32 A: Power Supply Solutions for Industrial Automation Systems
On this page
The reviewed power-supply label identifies HP P/N 901759-003, model DPS-500AB-32 A and revision 0D. Delta Electronics is named as manufacturer. It states 100-240 VAC, 50-60 Hz, 6 A input and 500 W maximum power.
Identification and delivery details
Four output designations are printed: +12.1VMAIN, +12.1VCPU, +12.1VG1 and +12.1VG2, each with a 16 A marking. The MAIN/CPU bracket gives 387.2 W maximum combined; the VG1/VG2 bracket gives 320 W maximum combined. These group limits must also remain within the overall 500 W maximum; they cannot be added into a larger supply rating.
The label says Made in China and carries an 80 PLUS GOLD mark. The March 31, 2026 note describes one new old stock unit with a one-year warranty. Its 1.5 kg weight field has no specified weighing basis. Printed CONT, HIPOT, B/I and ATE stamps do not substitute for a supplied test report.

Only the first photograph was reviewed because the nameplate provides identity and load limits. All eight source photographs and the unique clip are preserved. Output performance, efficiency and workstation compatibility were not independently tested.
Matching this part
Match HP 901759-003 and revision 0D against the existing power supply. Check the chassis mounting, harness lengths and each connector allocation before replacement; matching wattage alone does not establish fit.
Plan the load within each rail and combined-group limit as well as the overall 500 W ceiling. Request the exact host-system compatibility and a documented loaded-output check where required. The record's HP attribution does not prove compatibility with every Z2 configuration.
