Description Technical Specs Extended Information
M1-ATX is an intelligent vehicle (car, boat, electric cart, etc) 12V DC-DC ATX PC power supply designed for car pc applications. Designed to provide power and to control the ON/OFF switch of a motherboard (car PC) based on ignition status, M1-ATX is a wide input (6-24V) vehicle or car DC-DC ATX power supply capable of surviving tough car engine cranks (down to 5.7V) as well as transient over-voltage situations.

The M1-ATX comes with complete cable harness consisting of:
  • ATX cable extender plus HDD and Floppy power (9inch)
  • Power input cable harness terminated in 0.25' fastons (12inch, AWG18)
  • 2 pin M/B on/off power ON control wire harness (9inch)
  • set of LBJ (little black jumpers) to control various power sequencing schemes

Just connect it to your 12V or 24V car / boat / RV battery and power up your PC!

M1-ATX has 8 user selectable microcontroller driven timing modes, allowing you to choose up to 8 ignition/shutdown vehicle / car pc timing schemes via a built-in shutdown controller. By removing all user-selectable jumpers, M1-ATX becomes a traditional PC PSU with no ignition control (shutdown controller bypassed) and it can be used in non-vehicle computer applications.

Even if your computer is totally OFF, a PC will still consume a few hundred milliwatts, needed to monitor PC ON/OFF status. When the computer (car pc) is in the suspend/sleep mode, it will consume even more power, because the RAM needs to be powered at all times. The power consumption in the suspend mode is few watts.

No matter how big your car battery is, it will eventually drain your vehicle / car battery in a matter of days.

While in deep sleep mode, M1-ATX constantly monitors your car battery voltage levels, preventing deep discharge situations by automatically shutting down (using a built-in shutdown controller) until battery levels reach safe levels again.

No more dead car batteries, no more computer resets during engine cranks, along with multiple timing schemes, small formfactor and very competitive price makes the M1-ATX the premier solution for dc-dc ATX vehicle / car PC power supply solutions.

The M1-ATX form factor is compatible with all Casetronics enclosures.

NOTE: Do not try use this PSU with Pentium 4s! It works with all VIA mini-ITX boards and some low power Pentium's and AMD's, please check your motherboards specs and make sure that the CPU is not getting V(core) from the 12V rail, must be from the 5v rail. Stay away from motherboards that have 4 pin 12VATX connectors, that that is a good indication that the M/B is using 12V for V(core).
