myVolts

myVolts LD-A200WL 200W 19V-24V DC-ATX power supply

SKU CH-3HCE-F29AF MPN LD-A200WL

A compact 200 W DC-ATX module plugs straight into the motherboard, accepts 17-24 V input and delivers +12 V at 12 A, +5 V at 8 A.

  • Product typeAT
  • 200W DC-ATX power from a 17-24V source
  • Direct 24-pin ATX plug removes 24 loose cables
  • Overcurrent and short-circuit protection on every rail
  • Four cable lengths from 150mm to 320mm fit tight cases
  • Runs -5°C to 55°C for industrial and HTPC use

Direct ATX 200W DC-ATX Module

The myVolts LD-A200WL is a 200W DC-ATX power adapter board that plugs straight into a motherboard ATX 24-pin connector. It accepts a 17-24V DC input and delivers +12V up to 12A, +5V up to 8A, +3.3V up to 8A, +5VSB at 2A and -12V at 0.15A. High-quality PCB construction and an integrated oscillator running at 250-350 kHz provide stable output for compact systems.

Fits HTPC ITX and industrial builds

This module suits builders assembling Mini-ITX PCs, HTPCs, POS terminals, thin clients or industrial control boxes where an external 19-24V brick is preferred over an internal AC-DC unit. The direct-mount design removes 24 loose wires and saves internal volume. Builders who need ATX 12VHPWR, multiple PCIe power cables or an integrated AC inlet should look at a different form factor.

Single 200W 12V rail limit

The +12V output is capped at 12A, giving a maximum of 200W total across all rails. This ceiling decides whether a given CPU and GPU combination can be supported; if the target hardware draws more than 12A on the 12V line the board will trigger over-current protection and shut down.

Questions about this item

What clearance does the DC5525 input connector need inside the case?

The DC5525 jack sits on the board edge and requires the 320 mm pigtail to reach your external 17-24 V brick, so allow at least 12.6 in of routing space behind the motherboard tray.

Which cable must be connected first to avoid a no-post condition?

Plug the 24-pin ATX header into the motherboard before attaching the 4+4-pin CPU cable; the board draws its reference from the ATX socket and will not enable the 12 V rail until that connection is made.

When should the on-board protection fuses be checked or the module replaced?

If the 12 A 12 V rail or 8 A 5 V rail trips repeatedly under normal load, or the unit shuts down at -5 °C to 55 °C operating range, the over-current or short-circuit latch has likely degraded and the board should be swapped.
