myVolts LD-NAS200L 200W AT PCB power module

SKU CH-RTWG-G28B4 MPN LD-NAS200L

A compact 200W AT power module plugs straight into the motherboard ATX connector with 24 fewer wires, supplies +12V/12A, +5V/10A, +3.3V/8A, +5VSB/2A and -12V/.05A.

  • TypeAT
  • Direct motherboard plug removes 24 wires for a clean build
  • Compact PCB design fits small ATX cases without losing 200W output
  • Over-current and short-circuit protection shuts down output at peak load
  • Premium board material resists heat for reliable 12V 200W operation
  • Versatile connectivity serves MINI PCs, HTPCs, POS, ITX, servers and industrial systems

Direct-mount 200 W AT power module

The myVolts LD-NAS200L plugs straight into a motherboard ATX connector, removing 24 individual wires and fitting small-form-factor builds such as ITX cases, HTPCs, POS terminals and industrial control systems. It delivers 12 V at 200 W through a compact PCB assembly with integrated protection circuits.

Limits of the AT interface and fixed cable lengths

The module uses the AT standard and provides one ATX 24-pin, one CPU 4-pin, four SATA, two IDE and one DC 5525 connector. Cable lengths are fixed at 320 mm for DC, 210 mm for CPU, 200 mm for IDE and 150 mm for SATA, which restricts placement in larger enclosures.

12 V input requirement

Operation requires an external 12 V source; the board does not accept mains voltage directly. Builders without a suitable 12 V supply must choose a different power solution.
