  • TypeATX
  • Modern Standby support for near-instant wake from sleep

Compact 1U 500W ATX Supply

This 500 watt ATX power supply fits a 1U form factor and carries 80 PLUS Gold certification. It is built for compact workstations, small-form-factor servers and embedded systems that need efficient, standards-compliant power in a shallow chassis.

Zero RPM Fan and Resonant LLC Topology

A resonant LLC design with DC-to-DC conversion delivers clean, consistent output while reducing coil whine. The Zero RPM fan mode stops the cooling fan completely at low and medium loads, giving near-silent operation in noise-sensitive environments.

Modern Standby and Efficiency Limits

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. The Gold rating guarantees high efficiency at typical loads, but the 500 watt ceiling limits use in configurations that demand sustained output above that level.

  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode keeps the unit silent at low load
