myVolts Fanless ATX Power Module 16-24VDC 155x35x20mm

SKU CH-83ZV-CC06H

A fanless ATX power module accepting 16-24 VDC input and delivering 3.3 V, 5 V and 5 VSB rails with short-circuit and over-voltage protection

  • TypeAT
  • Fanless design keeps the system completely silent
  • High-quality solid capacitors on the PCBA deliver long service life
  • Tailored for mini-ITX motherboards with 24-pin ATX and 12 V AUX outputs
  • Over-voltage protection shuts the output at 1.5× rated voltage
  • circuit protection closes the output instantly on a fault

Fanless ATX Power Module

The myVolts Fanless ATX Power Module converts a 16 to 24 VDC input into standard ATX rails for mini ITX motherboards. It measures 155 by 35 by 20 millimetres and operates without a fan for completely silent running. Industrial-grade solid capacitors on the PCB are chosen for long service life.

Input range and protection limits

The module accepts 16 to 24 VDC and draws up to 12.0 A at 19 VDC with a surge rating of 12.0 A maximum. Over-voltage protection triggers at 1.5 times the rated output voltage, while short-circuit protection shuts the output down immediately. Typical efficiency is 85 percent or higher across the operating range.

Replaces noisy ATX PSUs in space-constrained builds

This unit replaces a conventional fan-cooled ATX supply where silence and a thin 20-millimetre profile are required. The jump is worthwhile for builders who need a compact DC-to-ATX solution with robust protection circuits. It is not suited for systems that demand higher peak currents than the 10.0 A on the 3.3 V rail or 6.0 A on the 5 V rail.

Questions about this item

Which input voltage range should I match to my DC source?

The module accepts 16 VDC to 24 VDC input; typical draw is 12.0 A at 19 VDC with a 12.0 A surge limit at the same voltage.

What 3.3 V rail current can I expect under load?

The +3.30 V output delivers a typical 8.0 A and peaks at 10.0 A with ripple kept to 50 mV.

How does the 24-pin ATX connector limit the power I can draw?

The unit provides ATX-standard rails — +3.30 V up to 10.0 A peak, +5.00 V up to 6.0 A peak and +5.00 VSB up to 2.5 A peak — all within the 85 % efficiency rating.
