myVolts LD-A450WL 450W AT power supply

SKU CH-KRV0-SMW3H MPN LD-A450WL

An AT power supply adapter board delivering 450 W from a 12 V input, plugging directly into a 24-pin ATX connector to remove 24 wires and save case space.

  • Product typeAT
  • Saves chassis space by plugging directly into the ATX connector, removing 24 wires
  • Delivers 450 W from a 12 V input with +12 V rail rated at 30 A
  • Built-in short-circuit protection shuts down output instantly when a short is detected
  • Over-current protection trips at peak current to safeguard connected components
  • High heat-resistant PCB construction maintains stable operation under sustained load

Power Adapter for Small ATX Boards

The myVolts LD-A450WL is a 450W AT power adapter board that plugs directly into a motherboard ATX connector. It delivers +3.3V, +5V, +12V and +5VSB rails with a total output of 450W from a 12V input. The unit includes short-circuit and over-current protection on all major rails.

Builders Needing Cable Reduction

This adapter suits compact systems where eliminating 24 loose wires saves space and improves airflow. It provides one CPU 4+4 pin, two SATA, one 2+6 pin graphics connector and two DC5525 outputs. Builders who need more SATA ports, additional PCIe cables or a standard ATX form factor should look elsewhere.

Direct ATX24Pin Motherboard Connection

The board mounts straight onto the 24-pin ATX header, removing the traditional cable harness entirely. DC cables measure 320mm, CPU and graphics cables 340mm, and SATA cables 390mm plus 190mm daisy-chain. This fixed geometry decides whether the adapter fits your chassis layout.

Questions about this item

How much power can the 12 V rail deliver continuously before the over-current protection trips?

The 12 V rail is rated for 30 A maximum load, and the built-in over-current protection will shut the output off if the peak current is exceeded.

Does the adapter board itself add noticeable heat or noise when running all day inside a closed case?

The board has no fan and relies on its high heat-resistance PCB material; it produces no audible noise and the supplier notes high heat resistance for reliable all-day operation.

What external power source must I already have to run this ATX adapter?

You need a 12 V DC supply connected to the DC5525 input jack; the board then distributes +3.3 V, +5 V, +5 VSB and +12 V to the ATX 24-pin, CPU 4+4-pin, SATA and graphics 2+6-pin connectors.
