13. Front Panel Audio header (10-1 pin AAFP)

The Front Panel Audio header is for a chassis-mounted front panel audio I/O module that supports HD Audio standard. Connect one end of the front panel audio I/O module cable to this header.

IMPORTANT!

• We recommend that you connect a high-definition front panel audio module to this header to avail of the motherboard's high-definition audio capability.
• If you want to connect a high-definition front panel audio module to this connector, set the HD Audio Controller item in the BIOS Setup to [Enabled].

14. ATX Power connectors (24-pin ATX\_PWR, 4-pin ATX12V)

Correctly orient the ATX power supply plugs into these connectors and push down firmly until the connectors completely fit.
