Designed to provide power and to control the ON/OFF switch of a motherboard (PC) based on ignition status, M3-ATX-HV is a very wide input (6-34V) vehicle or general purpose battery powered application DC-DC ATX power supply capable of surviving tough car engine cranks (down to 6V) as well as transient over-voltage situations.

The M3-ATX-HV is based on an electrically similar design to the M2-ATX but with dramatic size reductions (picoPSU plug-in style).

20pin ATX, 6-34V wide input range

Programmable timing settings using optional serial harness and utility

Intelligent shutdown controller

ON/OFF motherboard control

Solid Japanese Polymer capacitors

M3-ATX-HV comes equipped with a ATX, Molex HDD, SATA HDD and Floppy cable harness, jumpers, faston connectors and cables for Thump and Motherboard ON/OFF switch. Just connect to your 12V or 24V car/boat/RV battery and power up your PC.

Programmable shutdown / sleep modes via optional serial cable; Fits any motherboard equipped with a 20 or 24pin ATX connector; 100% silent, fanless, no moving parts; Operates from 6-34V; Multi-chemistry batteries supported; Highly efficient design - does not produce a lot of heat; Ideal for low power Intel Core processors as well as all Atom, VIA or AMD processors.

Notes: If your board has a 4 pin 12V P4 power connector, you will need add a Molex to 12V P4 Power Cable. Use the optional AC/DC Barrel Connector Cable to power from one of our AC Adapters (useful for testing).

Using an AC Adapter: Add the Barrel connector cable to connect one of our 60W, 80W or 150W AC Adapters.
