Replacement PSU for Optiplex XE

This 280 W unit fits Optiplex XE desktop and small form factor models. It uses the Y738P L280E-01 D499R part number and matches the DPS-280MB A A designation. The non-modular cable set includes a 24-pin ATX connector a 4-pin CPU plug a floppy power lead one SATA and one micro SATA connector. Active PFC handles 100 to 264 V input.

Upgrades for legacy Optiplex XE systems

The supply suits owners restoring or servicing an Optiplex XE DT or SFF chassis that requires the exact connector layout listed. Builders needing PCIe power plugs for a discrete graphics card cannot use this unit because it provides none. Systems that demand a higher wattage rating or a modular cable design should look elsewhere.

280 W fixed output decides fit

The single deciding specification is the 280 W maximum output combined with the fixed connector complement. If the target machine draws more power or requires additional SATA or PCIe leads this PSU will not support it.

Questions about this item

Does the Y738P L280E-01 D499R unit ship with the power cord that plugs into the wall socket?

The package contains the power supply itself with its fixed cables; the detachable mains cord is not included and must be sourced separately.

The supplier title mentions both Y738P and D499R — are they interchangeable revisions of the same 280 W PSU?

Y738P, KD98N, D499R and L280E-01 are listed as compatible part numbers for the Optiplex XE desktop and SFF, so any of them will fit and deliver the same 280 W output.

With only a 4-pin CPU connector and no 12 V graphics pins, can this 280 W PSU still run a discrete GPU?

The unit provides a 4-pin CPU connector and zero 12 V graphics pins, so it is intended for systems that rely on integrated graphics or very low-power cards that draw solely from the motherboard slot.
