  • Near-silent operation at low loads with Zero RPM fan mode
  • Clean, stable power delivery through resonant LLC topology with DC-to-DC conversion

Compatible Dell OptiPlex SFF Power Supply

This 235 watt ATX power supply is built as a direct replacement for Dell OptiPlex 760, 960, 580 and 780 small form factor systems. It matches the original AC235AS-00, PC9033, F235E-00, L235P-01, H235E-00 and H235P-00 part numbers for a straightforward swap.

Ideal for SFF Maintenance, Not for High-Power Builds

The unit suits IT teams and home users restoring or maintaining compatible OptiPlex SFF desktops where the original 235 watt supply has failed. Builders planning discrete graphics cards, high-wattage CPUs or full-size ATX cases should look elsewhere because the form factor and output are fixed at 235 watts.

Steady Output with Quiet Low-Load Operation

80 PLUS Gold certification and resonant LLC topology with DC-to-DC conversion deliver stable voltages and high efficiency during continuous workloads. Zero RPM fan mode stops the fan completely at low and medium loads, while Modern Standby support enables rapid wake-from-sleep without increasing idle power draw.

Questions about this item

What motherboard form factor and wattage must my Dell OptiPlex support for this 235 W ATX power supply to work?

Your system needs a standard ATX power connector and a 235 W power budget; the unit fits Dell OptiPlex 760, 960, 580 and 780 SFF chassis that originally shipped with 235 W supplies.

Will the Zero RPM fan mode stay silent if I keep my older mechanical hard drives and legacy PCI cards installed?

Yes, the fan remains off at low and medium loads regardless of drive or card count; only when total draw pushes the unit past its medium-load threshold will the fan spin up.

How can I confirm the 80 PLUS Gold efficiency and Modern Standby wake speed are active after installation?

Check the PSU label for the 80 PLUS Gold badge, then put the PC to sleep — a near-instant resume shows Modern Standby is functioning.
