SKU CH-3HPH-H1C5R

A 24 V ATX unit delivering 40 W with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and resonant LLC topology for clean, quiet power

  • TypeATX
  • Modern Standby support for fast wake and better low-load efficiency
  • 80 PLUS Gold certification for high efficiency, lower consumption and cooler running
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC with DC-to-DC conversion delivers clean power and reduces coil whine
  • 24 V 1.7 A output rated at 40 W for compatible ATX systems

40 W ATX power supply for low-power systems

This 40 W ATX unit delivers 24 V at 1.7 A and is designed for compact PCs or embedded boards that require a small, efficient power source. It suits builders who need a reliable supply for thin clients, digital-signage players or similar low-draw platforms.

80 PLUS Gold efficiency limits

The 80 PLUS Gold rating guarantees high efficiency at typical loads, reducing waste heat and fan noise, but the 40 W ceiling means it cannot support discrete graphics cards, multiple drives or high-wattage CPUs. Systems that exceed this envelope will need a higher-capacity supply.

Replaces older low-watt ATX units

It upgrades legacy 24 V ATX supplies that lack modern standby support, zero-RPM fan operation or Gold-class efficiency. The jump is worthwhile when faster sleep-wake cycles, quieter idle running and lower standby draw matter for the deployment.

Questions about this item

What does the 40W rating mean for my build?

The 40W rating is the maximum continuous power the unit can deliver at 24V and 1.7A. It suits low-power systems such as thin clients or embedded boards that draw modest current.

How does 80 PLUS Gold affect daily use?

80 PLUS Gold certification means the supply runs at high efficiency across typical loads, reducing waste heat and keeping fan speeds lower for quieter operation.

What does the ATX type determine for installation?

The ATX form factor fits standard ATX cases and uses the usual 24-pin main connector, so it mounts and cables like a regular desktop power supply.
