• I/O function
· 2 x PCI IDE devices
· 1 x FDC, 2 x serial ports(16550 fast com)
· 1x parallel port device /EPP/ECP/SPP
· 2x USB connector
· IrDA (infrared) connector
· Audio function
• Green function: Complied with APM (Advanced Power Management)
• ATX form factor
The ATX form factor has been defined to address four major areas of
improvement required of today’s predominant form factors.
· Enhance PC ease-of-use with all built-in I/O connector
· Better support for current and future I/O
· Reduce total system cost
· Better support for future processor technology
• Power supply regulation
Onboard switching voltage that supports appropriate power to the CPU and
future upgraded CPUs.
• Over-current protection circuit
With AIC 1569CS AH10 (protect CPU from accident short circuit), if system
current is over-loaded, the system will break down to protect direct damage of
the main board.
• Electrical--- Typical power supply
Below is reference for ATX case requirement on power supply.
