Dell OptiPlex Replacement Unit

The KHACHIMO power supply is built as a direct replacement for OptiPlex 760 960 580 780 desktops requiring a 235W ATX unit. It matches the original L235P and D235E series pin-outs and fits the proprietary chassis without adapters. System integrators and IT technicians can swap the unit in minutes to restore reliable power to aging workstations.

235 Watt Continuous Output

The unit delivers 235W of continuous power with 80 PLUS Gold efficiency across the load range. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency for fleet deployments. At typical office workloads the Zero RPM fan mode keeps the cooling fan off entirely for near-silent operation. Heavy sustained loads will spin the fan up and eventually hit the 235W limit, so the supply is not suited for discrete graphics upgrades or high-end CPU configurations.

ATX Form Factor Constraints

The ATX form factor and fixed cable harness limit installation to compatible OptiPlex small-form-factor and tower chassis. Proprietary motherboard connectors prevent use in standard DIY builds or non-Dell systems. Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine, but the 235W ceiling and connector layout define the practical upgrade boundary for these legacy platforms.

Questions about this item

Will this 235W unit fit the Dell OptiPlex 760, 580, 780 and 960 chassis I still use?

Yes, the supply is built for the OptiPlex 760, 580, 780 and 960 and replaces part numbers L235P-01, L235P-00, D235E-00, F235E-00, H235P-00, H235E-00 and PW116.

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

The fan will stay off at low and medium loads thanks to Zero RPM mode, and the system will wake from sleep almost instantly when Modern Standby is enabled in the BIOS.

Does the box include the mounting screws and power cables needed for a direct swap?

The unit ships as a direct replacement power supply; mounting hardware and cables are the ones already installed in the OptiPlex chassis.
