280 W replacement for Dell OptiPlex XE SFF

This power supply is a direct replacement for the Dell OptiPlex XE small-form-factor desktop. It delivers 280 W of continuous power and matches the original Y738P part number. The unit is supplied new and ready to install in compatible systems.

Verify part number and chassis before ordering

Confirm that your OptiPlex XE carries the Y738P or D499R label on the existing supply. The SFF chassis uses a proprietary connector layout, so standard ATX units will not fit or power the board correctly. Check that the physical dimensions and mounting points align with the original housing.

Suits owners repairing a Dell OptiPlex XE SFF

This unit suits anyone restoring a Dell OptiPlex XE small-form-factor PC to working order. Builders assembling a custom chassis or upgrading to a higher-wattage platform should look elsewhere, as the proprietary form factor and fixed 280 W output limit reuse in other configurations.
