EVGA Z690 CLASSIFIED (121-AL-E698)
The display can be used to show additional temperatures or configured to
provide live readings for voltages or temperatures. Detailed configuration
instructions for the POST Indicator are provided on Page 150.
20. USB 2.0 Headers
The USB2.0 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 USB2.0 ports on the chassis. These will function
similarly to the USB2.0 ports found on the motherboard's hardwired I/O hub,
but these 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 2.0 standard is 500ma @ 5V per port (header total is 1000ma) for
unpowered devices. If your USB device requires more power, it is
recommended to attach a powered USB Hub.
21. Supplemental PCIe 6-pin Power Connector
The 6-pin PCIe connector at the bottom of the motherboard provides
dedicated power to the PCIe x16 slots, augmenting the +12V power provided
by the 24-pin and power directly to the GPU (See Page 38 for more specifics to
the connector itself, and associated wiring/pinouts).
This connector is optional for a single card solution, but is recommended for
SLI, CFX, and dual-processor video cards.
22. PC Speaker
A small mono low-fidelity speaker, permanently attached to the motherboard.
Its primary use is for debugging purposes. A POST beep may indicate a
successful POST or various tones for USB initialization, while other beeps may
indicate an issue during the post process. Please see Page 152 for more details.
23. ProbeIt Header JAT1
The ProbeIt header is a means of live monitoring several different system
voltages in real-time with a multimeter. One terminal needs to connect to a
ground wire and the other to the specific voltage you want to monitor.
From top to bottom, the function for the JAT1 connector: VCORE, CPU
VCCIN AUX, CPU VDD2, CPU 1.05V, CPU 1.8V, PCH 1.05V, PCH 0.82V,
PCH 1.8V, VGT, GND.
24. CMOS Battery
The CMOS battery backup provides uninterruptable power to the BIOS/UEFI
to store its settings; otherwise, each power on would act as if the BIOS was just
reset. These batteries typically last several years and rarely need to be replaced.
