These are Gigabyte’s second-generation USB DAC-UP. On the rear panel, you’ll find two yellow USB ports on the same riser as the PS/2 port. The capacitors dedicated to audio processing tasks have been upgraded to high-end Chemicon audio capacitors, which can provide the backbone to support high resolution and high fidelity audio whether you’re playing games, listening to music, or watching TV or movies. There is a sensor under the CPU, two under the VRM, one under the chipset, another near the topmost PEG slot, and the last one is in the bottom-left corner of the board. To make sure all these fans can keep up with the heat output of your screamin’ components, Gigabyte installed six internal temperature sensors on the AX370-Gaming K5. Two of these headers, those labeled CPU_OPT and SYS_FAN3_PUMP, support 24W (2 Amp x 12 Volt) water pumps, and they also come with the requisite over-current protection. From the BIOS, these headers can be configured manually, or set to auto-detect the correct operating mode.
GIGABYTE MOTHERBOARD KEEPS RESTARTING INSTALL
There are a total of five fan headers on the motherboard, and all of them are four-pin hybrid connectors, meaning you can install voltage- or PWM-controlled fans/water pumps. If one or more of the LEDs located in the lower-right corner of the board remain lit during the boot sequence, then you can assume that the corresponding component needs some attention. These Diagnostic LEDs aren’t just for show, however, they offer at-a-glance clues to problems that may crop up when your PC becomes unbootable. This motherboard also features another series of LEDs, labeled CPU, DRAM, VGA, and BOOT (refers to the OS).

The software also lets you rearrange the locations of the RGBW signals and pins, letting you plug in a variety of third-party LED strips. All told, there are seven lighting effects and support for two 12V independently-programmable RGB, RGBW, and even UV-LED light strips. LEDs light up the VRM, audio shroud, the two PCIe graphics slots, the diffusers between the memory slots, and under the swappable accent overlay on the right-edge of the motherboard. Those LEDs, referred to as RGB Fusion, support up to 16.8 million colors and two distinct lighting zones.
