25. USB 3.2 Gen2 Type-C Header
The USB 3.2 Gen2 header is used to connect additional USB interface plugs to
the motherboard; these headers are most often used to connect the
motherboard to the chassis to enable the USB 3.2 Gen2 ports on the chassis.
These will function similarly to the USB 3.2 Gen2 Type-C port sometimes
found on a motherboard’s rear I/O hub, but can also be used for the chassis’
front panel USB, auxiliary ports that mount in the card slots, and certain
devices that directly connect to the header. The USB 3.2 Gen2 Header on the
Z690 CLASSIFIED is a shielded USB 3.2 Gen2 Header that supports up to
10Gb/s with USB 3.2 Gen2.
This USB 3.2 Gen2 Header has a power limit of 3000ma (3A) @ 5V.
26. USB 3.2 Gen1 Header
The USB 3.2 Gen1 header is used to connect additional USB interface plugs to
the motherboard. These will function similarly to the USB 3.2 Gen1 ports
found on the motherboard’s rear I/O hub, but can also be used for the chassis’
front panel USB, auxiliary ports that mount in the card slots, and certain devices
that directly connect to the header.
USB 3.2 Gen1 standard is 900ma @ 5V for unpowered devices. If your USB
device requires more power, it is recommended to attach a powered USB Hub.
Note: USB 3.2 Gen1 is more commonly referred to as USB 3.0.
27. BIOS SafeBoot Button
Pressing this button while the system is running will reboot the motherboard
directly into the BIOS without clearing CMOS. This feature is very useful for
situations where the motherboard is unable to complete boot due to a failed
overclock and the user does not want to erase the previous settings used.
28. BIOS Selector Switch
This switch toggles between physical BIOS chips. This board has 3 BIOS chips
as a permanent fixture. Each chip holds only the settings and profiles that have
been saved to the BIOS chip while active. This allows you to swap between
three physically different BIOS chips. This also makes it substantially easier to
hotflash a BIOS if needed. If instructions are needed for hotflashing a BIOS,
please contact EVGA Customer Service (Page 149 for contact info).
29. Front Panel Connectors
The Front Panel Connectors are the four main chassis connections. These
include the Power Switch, Power LED, Reset Switch, and HDD LED. The
Power and Reset switches are “Momentary Switches,” rather than “Latching
