Green PCB adapter board with ATX 24-pin, CPU 4+4-pin, SATA, IDE and DC 5525 connectors, 12.6in DC cable

myVolts

myVolts LD-A250WL 12V 250W power supply

SKU CH-ATCC-MEERJ MPN LD-A250WL

A 250 W AT power adapter board converts 12 V input into multiple rails with overcurrent and short-circuit protection, and includes ATX, CPU, SATA, IDE and DC connectors for compact builds

  • Product typeAT
  • Saves case space by plugging ATX connector directly onto motherboard eliminating 24 wires
  • Delivers stable power with 250W output across five rails including +12V at 16A
  • Protects components with overcurrent and short-circuit shutdown on all main rails
  • Fits tight builds with short cables: 320mm DC, 210mm CPU, 200mm IDE, 150mm SATA
  • Runs reliably from -5 to 55°C with built-in oscillator at 250-350 kHz

Adapter board for low-power ATX builds

The myVolts LD-A250WL is a 250 W adapter board that accepts a single 12 V DC input and delivers five regulated rails through an ATX 24-pin, a CPU 4+4-pin, one SATA, one IDE and a 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. Over-current and short-circuit protection shut down the outputs when limits are exceeded.

Suits compact systems needing a small ATX power

Builders of mini PCs, HTPCs, POS terminals, ITX cases, web servers or industrial controllers that run from a 12 V source will fit this board into tight spaces. It is not for systems that require more than 250 W total draw, need additional PCIe or EPS connectors, or must operate from an AC mains input without an external brick.

250 W total power rating from 12 V input

The board supplies up to 16 A on the +12 V rail, 6 A each on +5 V and +3.3 V, 2 A on +5 VSB and 0.05 A on -12 V, with an operating temperature range of -5 °C to 55 °C. If the combined load of all components exceeds 250 W, the protection circuits will shut the unit down.

Questions about this item

Will the over-current protection on the +12V 16A rail need resetting after it trips?

The protection turns the output off when peak current is reached; the board must be power-cycled to restore operation.

Which rail hits its limit first in a sustained 250W load?

The +12V rail at 16A reaches its maximum before the +5V 6A or +3.3V 6A rails under continuous draw.

How hot does the PCB get when running all day at 55°C ambient?

The board is rated for operation up to 55°C with 45–75% humidity; no active cooling is included, so case airflow must keep the PCB within that range.
