I/O port conflict: Avoid overlapping I/O addresses between onboard serial ports (3F8/2F8, etc.) and expansion cards.
Power consumption reference
The manual provides actual power consumption data (Core i7-4770S configuration):
Idle state: Approximately 10.5W (12V 0.38A+5V 0.68A+3.3V 0.78A).
CPU full load: about 85W (mainly 12V 6.5A).
S3/Sleep: Approximately 0.6~0.8W.
Suggested power supply: At least 350W ATX power supply to ensure sufficient power supply for PCIe expansion cards and hard drives.
Common troubleshooting checklist
Possible causes and solutions for the phenomenon
Power on, no display, CPU not installed properly or memory contact poor. Reinstall the CPU and check if the memory is securely plugged in; Clear CMOS
Check the WDT configuration when the system repeatedly restarts and the watchdog times out or the power supply is insufficient; Replace with a higher power supply
Serial communication failure COM1 mode switch (SW13) setting error check dip switch to ensure compatibility with device (RS-232/422/485)
USB 3.0 does not recognize that the driver is not installed or USB 3.0 is disabled in the BIOS to install USB 3.0 drivers; Enable XHCI in BIOS
RAID array cannot create SATA mode. If not set to RAID, enter BIOS and modify SATA mode to RAID. After restarting, press Ctrl+I
Check the FAN1 speed and clean the radiator if there is a malfunction of the automatic frequency reduction fan due to high temperature or dust accumulation on the heat sink; Adjust the speed control curve of the fan
PCIe expansion card unresponsive to resource conflicts or BIOS port configuration errors attempting to replace slot; Adjust PCIe Port Gen Speed in Chipset
