Is the Gigabyte z490 motherboard light always on?

Normal, the motherboard light should be the light indicating the capacitor. Because of the problem of maintaining the voltage, power, and current of the CPU or memory, large-capacity capacitors will store electricity on the motherboard. When the current fluctuates, it will be filtered out by the capacitors with large-capacity electricity to ensure the stability of the computer.

GIGABYTE Z490 UD motherboard does have LED lighting function, but whether it has a light bar depends on which model you buy.
