300 W ATX power supply

This 300 W ATX unit is built for compact desktops and small-form-factor workstations that require reliable, efficient power delivery. It suits system integrators and DIY builders who need a Gold-rated supply in a standard ATX footprint.

Modern Standby and zero-RPM operation

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. The zero-RPM fan mode keeps the cooling fan off at low and medium loads for near-silent operation, while resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine.

Replaces older 300 W units

This supply replaces legacy 300 W ATX units that lack 80 PLUS Gold certification and Modern Standby support. The upgrade is worth it when lower power consumption, quieter operation, and faster sleep-state transitions are priorities for the build.
