Automotive DC-DC ATX Power Supply

The Mini-Box M3-ATX-HV is a 95 watt intelligent DC-DC ATX power supply designed for vehicle and battery-powered PC applications. It accepts a wide 6 to 34 volt input range and delivers 120 watt peak output. The unit fits motherboards with 20 or 24 pin ATX connectors and operates silently with no moving parts.

Builders needing ignition-controlled vehicle power

This supply suits car PC, boat or RV builds that require automatic motherboard on and off control linked to ignition status. It includes amplifier anti-thump control and programmable shutdown modes via an optional serial cable. Builders needing AC mains input or power output above 120 watts peak should look at alternative solutions.

6 to 34 volt wide input range

The defining specification is the 6V to 34V DC input capability which allows operation through engine crank drops and voltage transients. The supply provides SATA, PATA and floppy power connectors for peripheral drives. It uses patent-pending HyperWatt technology to achieve high power density in a picoPSU plug-in style footprint.

Questions about this item

Is the Mini-Box M3-ATX-HV completely silent during continuous operation?

Yes, the supply is fanless with no moving parts, so it runs at 100 % silent even when delivering 95 W all day.

What motherboard power connector does the unit plug into directly?

It fits any motherboard equipped with a 20 or 24 pin ATX connector.

Can the 6 V to 34 V input range handle voltage drops from an older vehicle's starting battery?

The wide 6 V to 34 V input survives engine cranks down to 6 V and transient over-voltage, so it works with ageing batteries.
