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
Z490 FTW is a shielded USB 3.2 Gen2 Header and supports up to 10Gb/s
with USB 3.2 Gen2.
This USB 3.2 Gen2 Header has a power limit of 3000ma (3A) @ 5V.
27. USB 3.2 Gen1 Header
The USB 3.2 Gen1 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 Gen1 ports on the chassis.
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.
USB 3.2 Gen2 Type-A (found on the I/O Hub) shares the power limit of USB
3.2 Gen1 at 900ma @ 5V.
Note: USB 3.2 Gen1 is more commonly referred to as USB 3.0.
28. 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.
29. BIOS Selector Switch
This switch toggles between physical BIOS chips. This board has 2 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
two 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 150 for contact info).
30. Rear Panel Connectors (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 13 for a
component level breakdown.
