EP-6ZXM Form-Factor
The EP-6ZXM is designed with MicroATX form factor - the new industry
standard of chassis. The MicroATX form factor is essentially a Baby-AT base-
board rotated 90 degrees within the chassis enclosure and a new mounting
configuration for the power supply. With these changes the processor is relocated
away from the expansion slots, allowing them all to hold full length add-in cards.
MicroATX defines a double height aperture to the rear of the chassis which can be
used to host a wide range of onboard I/O. Only the size and position of this
aperture is defined, allowing PC manufacturers to add new I/O features (e.g.; TV
input, TV output, joystick, modem, LAN, etc.) to systems. This will help systems
integrators differentiate their products in the marketplace, and better meet your
needs.
• Smaller size promotes a smaller system size.
• I/O shield does not need to be retooled in an ATX 2.01 or later. The
mainboard should be used in an ATX 2.01 (or later) compliant case.
• A smaller power supply can be used. High integration on mainboard
reduces the system costs.
