Connectors for ATX (Multirail) Power Supply
See chapter 3.21 – 3.23 for cabling details!
(1) 24 pin connector (ATX layout)
(2) 4 pin connector (+12V, GND)
Note: The +12V supply (up to 12A) for processor and chipset is provided via the 4 pin
connector! Onboard voltage regulators convert the +12V input power to the appropriate
processor / chipset supply voltages.
(3) Processor Core Voltage Regulator: High Efficiency design for enhanced
power saving and less thermal dissipation loss.
Requirements for ATX Power Supply
for onboard components (worst case incl. processor, memory,
USB devices; w/o PCIe cards, w/o SATA drives)
The ATX power supply must support the minimum load
conditions as mentioned in the left chart.
Single 12V supply only supported by D3243-S!
