myVolts 19V DC-ATX Power Module 155 x 35 x 20 mm

Silent DC-ATX Module for Mini ITX

The myVolts 19V DC-ATX Power Module converts a 16 V to 24 V DC source into standard ATX rails for mini ITX motherboards. Its fanless construction makes it completely silent during operation. High-quality polymer capacitors on the PCBA contribute to a long service life. The compact 155 x 35 x 20 mm form factor fits space-constrained builds.

Replaces Bulky AC PSUs in DC Environments

This module replaces a conventional AC ATX power supply when a 19 V DC input is already available, such as in industrial or embedded systems. The jump is worthwhile when silence and a small footprint matter more than maximum output current. It is not suited for full-size ATX boards or systems drawing more than 10 A on the 3.3 V rail or 6 A on the 5 V rail. Builders who need higher peak power or additional PCIe connectors must look elsewhere.

Steady Output Under Continuous Load

Overvoltage protection shuts the output down at 1.5 times the rated voltage, while short-circuit protection cuts power instantly when a fault occurs. The unit maintains at least 85 percent work efficiency across the input range, limiting heat buildup during sustained use. Ripple stays within 50 mV on all rails even at peak currents of 10 A on 3.3 V and 6 A on 5 V. The fanless design relies on passive cooling, so airflow in the chassis remains essential for prolonged high-load scenarios.
