Compact DC-ATX power for small builds

This 220 W DC-ATX unit accepts a 16-24 V input and delivers standard ATX output rails for compact systems. It suits builders assembling mini-ITX PCs, thin clients or embedded appliances that run from an external DC brick or battery bank. The 80 PLUS Gold certification confirms high efficiency across typical loads.

Integrates with external DC source and ATX

The supply replaces a conventional AC-ATX PSU and connects directly to a 16-24 V DC source, freeing the chassis from a bulky AC inlet and internal cabling. Its ATX form factor fits standard mounting points while the DC-to-DC topology provides clean power to the motherboard, CPU and peripherals without additional conversion stages.

Sustained output with silent low-load operation

Under continuous load the resonant LLC topology maintains stable voltages and suppresses coil whine, while the 80 PLUS Gold efficiency keeps waste heat low. When demand drops the Zero RPM fan mode stops the fan completely, eliminating audible noise during idle or light workloads. Modern Standby support allows rapid wake-from-sleep without sacrificing efficiency.

How much continuous power can the 220W unit deliver before protection engages?

The power supply is rated for 220W of continuous DC-ATX output from a 16-24V input.

Does the Zero RPM fan mode stay silent during all-day operation?

At low and medium loads the fan stops completely; under sustained high load it will spin to maintain temperature.

What input voltage source is required for this DC-ATX module?

A 16-24V DC source such as a compatible AC-DC adapter or battery system is needed to power the unit.
