See an mp3Car review of this product HERE.

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.

Firmware on the M4-ATX can be changed to accommodate different behaviours. OEM / reseller integration is welcome. Please send en email to with your custom requirements.
