SKU CH-P3M8-189KF

An ATX power supply delivering 24 V at 2.2 A with 75 W output, 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and resonant LLC topology with DC-to-DC conversion

  • TypeATX
  • Modern Standby support for near-instant wake times
  • 80 PLUS Gold efficiency lowers power draw and heat
  • Zero RPM fan mode keeps operation silent at low loads
  • Resonant LLC topology with DC-to-DC conversion delivers stable, clean power
  • ATX 24 V 2.2 A design rated for 75 W continuous output

Purpose-built 24 V ATX supply

This 75 W ATX unit delivers a fixed 24 V rail rated at 2.2 A and is designed as a direct replacement for the TDK-Lambda SWS75-24. It suits industrial PCs, embedded appliances and test rigs that require a single-voltage ATX-form-factor source with modern standby support.

80 PLUS Gold with zero-RPM mode

Gold certification confirms high efficiency across the load range, reducing waste heat and fan demand. The resonant LLC topology with DC-to-DC conversion supplies clean power and minimises coil whine, while the zero-RPM fan mode stops the fan completely at low and medium loads for silent running.

Efficient thermals and low power draw

High Gold-rated efficiency keeps internal temperatures modest during normal operation, allowing the fan to remain off for extended periods. When the fan does spin, it moves only the air needed for the actual load, so acoustic output and power consumption stay low in typical use.

Questions about this item

What 80 PLUS rating does this 75 W ATX unit carry and what does it mean for daily use?

It is 80 PLUS Gold certified, so the supply runs at high efficiency, draws less power from the wall, produces less heat and keeps fan noise lower under typical loads.

What physical space and mounting does the ATX form factor require in my case?

The unit follows the standard ATX footprint, so it fits any case with an ATX power-supply bay and uses the usual four rear mounting screws.

How do I connect the 24 V output and which step do builders often miss?

Wire the 24 V rail to the matching 24 V input on your board or device, then verify the 2.2 A limit is not exceeded; the step most often missed is confirming the load stays within that 2.2 A rating before powering on.
