The M2-ATX-HV is an intelligent, high power 12V DC-DC ATX PC power supply for car PC and battery powered applications. Designed to provide power and to control the ON/OFF switch of a motherboard, based on ignition status, battery voltage, or time. The M2-ATX has a wide voltage input of 6 to 32V and it is capable of surviving tough car engine cranks as well as transient over-voltage situations. M2-ATX-HV has eight user selectable micro-controller driven timing modes, allowing you to choose up to eight ignition/shutdown car PC timing schemes via a built-in shutdown controller. By removing all user-selectable jumpers, M2-ATX-HV 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, which is needed to monitor PC ON/OFF status. When the computer is in the sleep mode, it will consume even more power, because the RAM needs to be powered at all times. The power consumption in the sleep mode is few watts. No matter how big your car battery is, it will eventually be drained by the computer. While in sleep mode, M2-ATX-HV 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 form factor and very competitive price makes the M2-ATX-HV the premier solution for DC-DC ATX vehicle/car PC power supply solutions. M2-ATX-HV is compatible with all of our cases and with most Casetronics and Morex enclosures.

NOTE: M2-ATX-HV provides up to 8A on the 12V rail, making it ideal for operating most P4, P4-M, Celeron, AMD systems. Low power Geode and VIA processors (C3, C7) will work as well, leaving ample power for 12V or 5V peripherals.
