  • 5 to 55°C operating range suits industrial and embedded use

Compact ATX adapter for low-power builds

The myVolts LD-A450WL is a 450W adapter board that plugs straight into a 24-pin ATX motherboard connector and runs from a single 12V DC source. It delivers 30A on the 12V rail, 10A on 5V and 3.3V, plus 2A on 5VSB, making it suitable for mini PCs, HTPCs, POS terminals and other space-constrained systems.

Suited for tight enclosures.

Builders fitting ITX cases, industrial control boxes or advertising displays will appreciate the cable-free ATX header and short 12.6in DC lead. Systems that need more than 30A on the 12V rail, multiple GPU power connectors or a standard AC-input PSU should look elsewhere.

Direct header install with fixed cables

Installation consists of seating the 24-pin board onto the motherboard and routing the pre-wired 13.4in CPU, 13.4in graphics 2+6pin, 15.4in SATA and 7.5in SATA leads. Over-current and short-circuit protection shut the outputs down if limits are exceeded; the fixed cable lengths can restrict routing in larger chassis.

Questions about this item

What external 12V power source do I need to run this 450W adapter board?

You must supply a 12V DC source capable of delivering the full 450W load; the board has no internal AC input and relies entirely on that external supply.

Can I keep my existing SATA drives and graphics card when installing this board?

Yes, the board provides two SATA connectors and a 2+6pin graphics card connector so your current drives and GPU can plug in directly.

How do I confirm the board is delivering power correctly after I connect everything?

The built-in over-current and short-circuit protections will shut the output off if any rail exceeds its peak current or is shorted, so a stable boot with all components running indicates normal operation.
