Dell W4827 250W Internal PSU

This Dell W4827 is a 250-watt internal power supply with active PFC and dual Serial ATA connectors. It is built for Dell OptiPlex GX280 and GX280n desktops plus Dimension 8400 and 4700 systems needing a direct replacement unit.

Input voltage range and output limit

The unit accepts 110 V AC and 220 V AC mains input and delivers a maximum of 250 W combined output. Dual Serial ATA power leads are provided, so builders requiring legacy Molex or PCIe connectors must source adapters separately.
