2. PCI-E 1X: For other expansion cards (e.g., sound cards, network cards), use the PCI-E 1X slot.
3. NGFF M.2 Key A&E (WIFI+Bluetooth): Install compatible WIFI+Bluetooth modules into this dedicated M.2 slot.

3.6 Power Connections

1. Connect the 24-pin ATX power connector from your power supply unit (PSU) to the 24-pin ATX power socket on the motherboard (Figure 2).
2. Connect the 4-pin ATX CPU power connector from your PSU to the ATX CPU 4-pin socket near the CPU (Figure 2).
3. Important: This platform requires a powerful power supply. Ensure your PSU is at least 500W for stable operation.

3.7 Front Panel and I/O Connections

1. Connect the front panel headers (Power SW, Reset SW, Power LED, HDD LED) to the corresponding pins on the motherboard (Figure 5).
2. Connect front USB 2.0 and USB 3.0 headers to the F-USB2.0 and F-USB3.0 headers respectively (Figure 2, Figure 6).
3. Connect front audio headers to the F-Audio header.
4. Connect system fans (SYS-FAN) and CPU fan (CPU-FAN) to their respective headers (Figure 2).

3.8 Rear I/O Ports

The rear I/O panel provides the following ports:

• PS/2 ports for keyboard/mouse
• VGA (D-Sub) port
• DVI-I port
• HD (HDMI) port
• USB 2.0 ports
• USB 3.0 ports
• 1x RJ45 Gigabit Ethernet port (Figure 8)
