6-24V Intelligent Automotive ATX Power Supply
Before you start...
Please take a moment and read this manual before you install the M1-ATX in your
vehicle. Often times, rushing into installing the unit can result in serious damage
to your M1-ATX board, computer and probably your car's electrical system.
The M1-ATX board has several wires that need to be installed in various places.
When installing, always double check the polarity of your wires with a voltmeter.
NEVER use the cigarette plug as a power source, often times the contacts are not capable of delivering high current to
your PC.

1.0 Introduction

Thank you for purchasing the M1-ATX power sequencer / vehicle ATX power supply.
The M1-ATX was designed to work with a wide variety of main boards such as the VIA mini-ITX motherboards as well as
low power Pentium-M or Celeron or Atom . Please note that powering full power Pentium 4 or certain AMD systems is
not recommended due to 12V rail power limitations.

Summary of Contents for mini-box M1-ATX

  • Page 1 Thank you for purchasing the M1-ATX power sequencer / vehicle ATX power supply. The M1-ATX was designed to work with a wide variety of main boards such as the VIA mini-ITX motherboards as well as low power Pentium-M or Celeron or Atom . Please note that powering full power Pentium 4 or certain AMD systems is not recommended due to 12V rail power limitations.
  • Page 2 80 volts (load dump). Most of the times, your battery will stay at 13.5V (while car is running) but extra precautions need to take place in order to prevent such situations. M1-ATX can operate as low as 6V and as high as 28V while providing strict regulation on all rails along with input voltage clamping and reverse protection.
  • Page 3 Ignition=OFF. Nothing happens. M1-ATX is waiting for ignition signals. Ignition=ON. M1-ATX waits for few seconds then turns on the 5VSB rail. After another second M1-ATX sends an “ON” signal to the motherboard via the 2 wires connected to the motherboard’s ON/OFF pins. The motherboard will turn ON and your system should start booting.
