Dell OptiPlex 5250 and 5260 compatible PSU

This KHACHIMO power supply replaces the original H155EA-01, AC155EA-01, HPY3Y and X1V9H units used in Dell OptiPlex 5250 and 5260 desktops. It is an ATX form-factor unit supplied new and tested working. The component is intended for owners of those specific models who need a direct replacement for a failed or ageing factory power supply.

Upgrade when the original unit fails

The jump is worth it when the existing power supply has stopped working, causes unexpected shutdowns or delivers inconsistent voltage to the motherboard. Builders working on non-OptiPlex chassis or systems requiring a different connector layout cannot use this unit. It addresses the need for a like-for-like spare rather than a higher-wattage or modular upgrade.

Questions about this item

Will the H155EA-01 power supply fit my Dell OptiPlex 5250 chassis?

This unit is built for OptiPlex 5250 and 5260 systems using the H155EA-01 or AC155EA-01 form factor, matching the proprietary mounting points and connector layout of those models.

What is the common installation mistake with the HPY3Y connector on this power supply?

The HPY3Y main power connector is keyed for a single orientation; forcing it in upside-down bends pins and prevents the system from posting, so align the notch before pressing firmly until it clicks.
