These days we are working with VIA Technologies PC-1 series mainboards and compared with standard main boards these boards have special features and advantages.

Main advantage is, its lower price and low power consumption.

Like most modern motherboards these boards also have built-in Sound cards, Network adapters, SATA Support and build-in Video interface.

VIA PC-1 series is specially design for low power computing and users may be able to run this mainboard with 150W power supply.


There are several PC-1 mainboards are available and we are mainly worked with following units,

PC-1000 Mainboard

  • Powered by VIA C3 – 800MHz microprocessor
  • 100/133 MHz FSB
  • DDR-I Memory up to 1GB.
  • VGA up to 64MB
  • 4 USB 2.0 ports
  • 10/100 LAN interface
  • 1 PCI Slot
  • Realtek AC97 audio codec
  • Mini ATX form factor (170mm x 170mm)

Price : Rs. 5000.00 (Sri Lanka Rupees)

PC-3500 Mainboard
