AT power supply for small ATX boards
The myVolts LD-A250WL is a 250W AT-type power supply adapter board designed for small ATX motherboards. It plugs directly into the 24-pin ATX connector to eliminate loose cables and save space inside compact cases. Builders upgrading or repairing legacy systems will appreciate the direct-mount design. It draws 12V DC input and delivers regulated rails for standard desktop components.
250W output with +12V at 16A
The single specification that decides compatibility is the 250W total power rating with a +12V rail rated at 16A. The unit also provides +5V at 6A, +3.3V at 6A, +5VSB at 2A and -12V at 0.05A. If your build demands more 12V current or higher total wattage this adapter will not meet the requirement.
Built-in protection and short DC cables
Over-current and short-circuit protection shut down the affected rails when limits are reached. The board uses a PCB construction rated for high heat resistance and operates with an internal oscillator between 250 and 350 kHz. Cable lengths are fixed at 320 mm for the DC input, 210 mm for the CPU 4+4-pin, 200 mm for IDE and 150 mm for SATA, so the power brick must sit close to the motherboard.

Questions about this item
How much power does the 250W rating actually deliver to a small ATX board?
The board provides up to 250W total across +12V at 16A, +5V at 6A, +3.3V at 6A, +5VSB at 2A and -12V at 0.05A, matching the needs of compact ATX systems.
What does the DC5525 input interface limit in practice?
The DC5525 jack accepts a 12V external source, so the 250W output is capped by whatever 12V brick or adapter you connect.
What clearance does the ATX24Pin connector need to plug straight onto the motherboard?
The adapter mounts directly onto the 24-pin ATX header, eliminating 24 loose wires and fitting inside cases built for small ATX boards.
