myVolts DC-ATX 120 W 12 V inline power supply

SKU CH-EQXR-WJEZ6

Compact 120 W inline ATX module converts 12 V DC input to standard 24-pin rail outputs in a 35 x 45 x 18 mm board

  • TypeAT
  • Compact 35 x 45 x 18 mm board fits tight builds
  • Delivers 120 W continuous power from a single 12 V source
  • 24-pin ATX connector powers standard motherboards directly
  • 5 V, 3.3 V and 12 V rails rated within 1.5 % tolerance
  • Peak headroom up to 10 A on the 12 V rail

Compact 12 V ATX module

This 120 W inline board converts a single 12 V source into standard ATX rails including 12 V, 5 V, 3.3 V, 5 VSB and -12 V. It fits miniature builds, embedded systems or test benches where a full-sized supply cannot be used. The 24-pin connector plugs directly into the motherboard. No external AC mains connection is required.

Builders with a 12 V DC source

Suits integrators powering a board from a 12 V battery, vehicle supply or regulated brick. Not suited for systems drawing more than 120 W combined across all rails. Builders needing ATX 12 V 2×2 or 2×4 CPU connectors must add a separate adapter.

120 W total output

The 120 W rating governs every rail simultaneously; the 12 V line peaks at 10 A while 5 V and 3.3 V each peak at 8 A. Exceeding the combined limit will trigger protection or voltage drift.

Perguntas sobre este artigo

What maximum power does the 12 V input deliver to the 24-pin ATX connector?

The unit is rated for 120 W continuous output from a 12 V source, with a 10 A peak on the 12 V rail.

Will the 35 x 45 x 18 mm board fit inside a standard Mini-ITX case?

The module itself measures 35 x 45 x 18 mm without cables, so it fits in most Mini-ITX builds if cable routing is planned.

How do I connect the 12 V source without reversing polarity?

Solder or crimp the 12 V input leads to the marked pads on the board, observing the printed polarity symbols before powering on.
