Front Panel Audio Connector; Rear Panel I/O (Figure 2) - EVGA Z690 CLASSIFIED User Manual

EVGA Z690 CLASSIFIED (121-AL-E698)
Switches," which means the connection between two posts only needs a brief
moment to turn on the device, as opposed to requiring a constant connection.
For example, the Power and Reset switches can be triggered instantly with a
screwdriver by simultaneously touching the + and - posts.
The Power LED will power on with the system, indicating the system is on and
can blink in conjunction with CPU activity.
HDD LED blinks during access to SATA devices, but not M.2 SSDs.

30. Front Panel Audio Connector

This header is used to plug in the audio cable included with most PC chassis.
This connector is required for audio recording and/or playback via the audio
connectors on the chassis. This header uses the standard "HD Audio" jack.
Some chassis may provide two headers: one labeled HD Audio, and one labeled
AC'97; AC'97 cables are not compatible with this header on the Z690
CLASSIFIED.

31. Rear Panel I/O (Figure 2)

This is the section referred to as the I/O Hub. This panel contains the
hardwired USB, Sound, and Ethernet connections. Please see Page 14 for a
component level breakdown.
* There are two numeric references for PCI-Express: one is mechanical (the physical
length on the motherboard), while the second is electrical (the number of PCIe lanes
available to the slot from the CPU, PCH, or both).
PCI-Express was designed to be universal; e.g. you can install x1 devices, such as sound
cards or USB controllers, into an x16 slot. Similarly, some applications might only use
certain parts of a device (e.g. compute apps), requiring only a single PCIe lane to
accomplish its task without affecting performance. This is why there are x16 mechanical
slots with an x1 electrical PCIe lane. Using the entire length of a PCIe slot is
unnecessary, nor does it cause an adverse effect to use a shorter form-factor bus card in
a slot that physically can hold a larger form-factor bus card.
