Intelligent Automotive / Car DC-DC ATX PC Power Supply

http://www.cartft.com/ - company specialized in Car PCs solutions.
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 mailto:%20m1-atx@mini-box.com with your custom requirements.
