myVolts LD-NAS200L 12V PCB AT power supply

SKU CH-QBYS-K5HXJ MPN LD-NAS200L

A 12 V AT power board delivering 200 W directly to a 24-pin motherboard connector with CPU, SATA, IDE and DC5525 outputs, plus over-current and short-circuit protection

  • TypeAT
  • Reliable operation with over-current and short-circuit protection
  • Space saved by plugging directly into the ATX motherboard connector
  • High heat resistance from premium PCB material at 200W
  • Versatile power for HTPC, POS, ITX and industrial systems
  • Clean build with 24-wire elimination and multiple SATA connections

Compact 200W AT power board

This 12V 200W PCB module plugs straight into a motherboard ATX connector and removes the need for a standard 24-pin cable bundle. It suits builders of small-form-factor PCs, HTPC units, POS terminals and industrial control boxes where internal space is tight. Over-current and short-circuit protection shut the output down if peak load is exceeded. The board delivers +5VSB at 2A, +5V at 10A, +3.3V at 8A, +12V at 12A and -12V at 0.05A.

Practical limits of the AT interface

The AT form factor provides only a single 12V rail and lacks the extra 12V CPU pins, PCIe power connectors and modern standby rails found on ATX12V or EPS designs. Consequently it cannot power graphics cards that need dedicated 12V feeds or motherboards that require 24-pin ATX plus 8-pin EPS. Cable lengths are fixed at 320mm for the DC input, 210mm for the CPU 4-pin, 200mm for each IDE lead and 150mm for each SATA lead.

Check your build before ordering

Verify that your motherboard uses a 24-pin ATX power socket and a 4-pin CPU power header, not an 8-pin EPS connector. Confirm the chassis can route the 320mm DC cable from the external 12V source to the board location. Count SATA and IDE devices against the four SATA and two IDE plugs provided. Ensure the 12V brick you pair with the board can supply the full 200W load continuously. Buyers needing PCIe power connectors or 24-pin ATX with 8-pin EPS should look elsewhere.

Questions about this item

Should I pick the 200W version or a lower-wattage board?

The LD-NAS200L delivers 200W from a 12V input and plugs straight into the ATX24Pin and CPU4Pin headers, so choose it when your build needs that full output.

What does the 200W rating actually provide inside my case?

It supplies +12V at 12A, +5V at 10A, +3.3V at 8A, +5VSB at 2A and -12V at .05A through the onboard connectors, powering CPU, drives and motherboard logic directly.

Which connectors does the DC5525 interface support in practice?

The board includes one DC5525 jack for 12V input plus an ATX24Pin, a CPU4Pin, four SATA, two IDE and the same DC5525 for output distribution.
