M4-ATX is an intelligent, high power, vehicle (car / boat / electric cart) DC-DC ATX PC power supply designed for use with car pc or general purpose battery powered applications. Designed to provide power and to control the motherboards's ON/OFF switch based on ignition status, M4-ATX is a wide input (6 to 30V) vehicle / car / battery operated ATX power supply capable of surviving tough car engine cranks (down to 6V) as well as transient over-voltage situations. Connect it to your car / boat / RV / solar battery and power up your PC! By using Patent Pending HyperWatt[TM] technologies, M4-ATX packs an impressive amount of power relative with its small footprint. M4-ATX has several key advantages over traditional power supplies:

- 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 6-30V, multi-chemistry batteries supported.
- Highly efficient design, does not produce a lot of heat.
- Works with any Intel Core Duo as well as all VIA or AMD processors.

M4-ATX System Tray Monitor & Setup Application
This install kit provides two applications. M4ATXTray.exe which allows monitoring the M4-ATX power supply voltages and temperature (needs to be connected thru a USB cable to the computer).The application adds a small icon on windows system tray which on mouse over displays the voltages and temperature, and can be customized with several skins.

The second application M4_ATX.exe allows to setup various parameters of the power supply like ignition voltage limit or shutdown voltage limit.
