280W ATX Power Supply for Desktop Replacement

This 280W ATX power supply is designed to replace the XE-DT 300W D300ED-00 and L300E-00 units in compatible desktops. It suits builders restoring or upgrading small-form-factor systems that require a standard ATX form factor with Gold-rated efficiency.

Standard ATX Fit with Zero RPM Fan Mode

Installation follows the usual ATX mounting pattern and connector layout for a direct swap in supported chassis. The Zero RPM fan mode stops the fan at low and medium loads, so builders should verify that case airflow remains adequate when the fan is idle to avoid localized heat buildup.

Gold Efficiency with LLC Resonant Topology Under

The 80 PLUS Gold certification and resonant LLC topology with DC-to-DC conversion maintain high efficiency and tight voltage regulation during sustained operation. Modern Standby compatibility enables deeper sleep states and fast wake times, while the fan remains off longer under continuous moderate loads for quieter performance.
