Direct replacement for OptiPlex SFF

This WMtec server power supply replaces Dell part numbers FR610, WU136, PW116, 67T67, RM112 and R224M inside OptiPlex 760, 960, 780 and 580 small-form-factor chassis. It delivers a maximum output of 235W to restore original power capacity. The unit is built new to match the factory form factor and connector layout.

Thermals noise and 235W power draw

Rated for 100-240V input at 4.5A across 50-60Hz mains, the supply operates within standard office voltage ranges. Internal protection circuits manage heat and current at the rated 235W load. The original cooling design is retained, so acoustic profile matches the system's stock behaviour under typical workloads.

Fits OptiPlex 760 960 780 580 SFF

Mechanical dimensions and mounting points align with the listed OptiPlex SFF models, requiring no chassis modification. All native power connectors are present for motherboard, drives and expansion cards. Builders needing higher wattage or a different form factor cannot use this unit.

Questions about this item

How do I install the 235W unit in an OptiPlex 760 SFF and which step is often missed?

Slide the supply into the chassis until the latch clicks, then connect the 24-pin motherboard plug and the 4-pin CPU plug; the step most often missed is securing the retention screw that locks the handle in place.

What maintenance or replacement will the FR610 need over time?

The internal fan bearings are the only wear item; expect to clean dust from the intake grille every 6–12 months and replace the fan if noise or vibration appears.

What limit appears first when the PSU runs at full 235W continuously?

The 4.5A input current ceiling at 100V is reached first, so sustained maximum output requires a supply voltage nearer 240V to avoid tripping the primary protection.
