Silent DC-to-ATX power for mini-ITX builds

The myVolts LD-200W is a fanless DC-to-DC module that converts a 16–24VDC source into standard ATX rails for compact motherboards. It suits builders who need a completely silent power solution inside space-constrained chassis.

Zero noise, 85% efficiency at 19V input

With no moving parts the unit runs 100% silent while delivering up to 200W continuous power. Typical draw is 12A at 19VDC and efficiency reaches 85% or more. Over-voltage protection trips at 1.5× rated output and short-circuit protection shuts the rails down instantly.

Ready-to-wire loom for immediate assembly

The package includes a 24-pin ATX to 12V AUX adapter, a 4-pin CPU power lead and a 4-pin floppy drive connector so the module plugs straight into a mini-ITX board. No extra cables or configuration are required.

Questions about this item

How do I connect the 24-pin ATX cable and the 12 V AUX lead to my mini-ITX motherboard?

Plug the 24-pin ATX connector into the motherboard main power socket, then attach the separate 12 V AUX lead to the CPU 4-pin header; both cables are included in the box.

What maintenance will the fanless 200 W module need over time?

With no moving parts, only occasional dust removal from the 155 × 35 × 20 mm PCB is required; the high-quality capacitors are rated for long life.

At what input voltage does the 85 % efficiency rating apply?

The 85 % or higher efficiency figure is specified at 19 VDC input.
