Compatible Dell Optiplex Models

This refurbished DELL X9072 power supply is designed for Optiplex GX 320, 520 and 620 systems. It replaces the original unit in those chassis and supports the factory component layout. Builders working on other Dell models or custom cases should verify fitment before ordering.

280 W Maximum Output

The unit delivers up to 280 W of continuous power through a 24Pin main connector, a 4 Pin ATX +12V connector, two SATA power connectors, one IDE power connector and one floppy drive connector. Systems requiring higher wattage or additional PCIe power cables cannot use this supply.

Sustained Load Behaviour

Under continuous demand the supply maintains its rated 280 W output across the provided rails. The fixed connector set limits expansion to legacy SATA, IDE and floppy devices, so long-term upgrades are constrained by the available plugs rather than thermal headroom.

Questions about this item

What does the 280 W maximum power mean once the unit is installed in a real machine?

It sets the total continuous output the supply can deliver across all rails, so the combined draw of CPU, drives and cards must stay below 280 W.

What interface does the 24-pin main connector use and what does it cap in practice?

The 24-pin ATX connector feeds the motherboard and is limited by the 280 W overall budget of the supply.

What does the unit physically need to fit or mount in an Optiplex GX 320, 520 or 620?

It is designed to the Dell Optiplex GX 320, 520 and 620 chassis, so the screw holes, bracket and connector placement match those cases directly.
