Replacement 235 W PSU for OptiPlex SFF

This new 235 W ATX power supply replaces the original unit in Dell OptiPlex 580, 760, 780, 960 and 980 small form factor desktops. It matches part numbers H235P-00, L235P-01, L235P-00, H235E-00, F235E-00 and L235Es-00. The unit is built for systems that require a compact PSU with the Dell-specific connector layout.

Direct swap for failed or ageing OEM units

It replaces power supplies carrying references FR610, WU136, PW116, 67T67, RM112 or R224M. The upgrade is worth it when the original unit no longer holds voltage under load, shows capacitor bulging or causes random shutdowns. Buyers who need higher wattage for discrete graphics cards or additional drives cannot use this 235 W model.

Straightforward installation

The PSU fits the SFF chassis and connects through a 24-pin mini ATX main connector, a 4-pin ATX CPU connector, a standard SATA power lead and a 2-pin slimline SATA connector. The main obstacle is cable routing in the tight Dell chassis; ensure the 24-pin mini plug seats fully or the system will not post.

Questions about this item

Does the 24-pin mini ATX connector match the motherboard header on an OptiPlex 780 SFF?

Yes, the unit provides a P1 24-pin mini ATX power connector designed for the Dell OptiPlex 580 760 780 960 980 SFF chassis.

Which cables must be plugged in before securing the PSU with the rear screws?

Connect the P1 24-pin mini ATX, P2 4-pin ATX, P3 SATA power and P4 2-pin slimline SATA cables first; the short SFF loom makes routing difficult after the unit is screwed down.

When should the internal fan be cleaned to maintain airflow in the 235 W unit?

Blow dust from the fan intake every 6 to 12 months; the compact SFF case restricts airflow, so a clogged fan reduces cooling for the 235 W supply.
