  • Product typeATX
  • Faster wake-from-sleep with Modern Standby support
  • Lower power draw from 80 PLUS Gold efficiency

  • Cleaner power delivery through resonant LLC with DC-to-DC
  • 500 W ATX output with 12-pin and 8-pin connectors

Compact ATX supply for modern standby systems

This 500W ATX power supply uses a 1U form factor and resonant LLC topology with DC-to-DC conversion to deliver clean power for compact builds. It targets system integrators and enthusiasts who need reliable efficiency in space-constrained chassis while supporting modern standby sleep states for instant wake capability.

Gold efficiency limits heat at typical loads

The 80 PLUS Gold certification guarantees high efficiency across standard load ranges, reducing power draw and thermal output during everyday use. At low and medium loads the zero RPM fan mode stops the fan completely, eliminating acoustic noise, though sustained heavy loads will engage active cooling and increase audible output.

Fixed cables suit permanent installations

The unit provides a 12-pin and an 8-pin connector without modular cables, simplifying cable management in small enclosures but limiting reconfiguration for different component layouts. Resonant LLC topology suppresses coil whine for quieter operation, and the 1U height fits rackmount or slim tower cases where vertical clearance is restricted.
