The AMS1117 is a very common linear voltage regulator chip, usually used to provide a stable 3.3V or 5V voltage output, and is widely used in a variety of electronic devices, including some computer motherboards. However, it is not a standard component of the computer motherboard, but exists as an auxiliary component of the power management section.

On a computer motherboard, the AMS1117 may be used to provide a stable voltage to certain low-power circuits, such as USB ports, auxiliary power supply to memory bars, or other components that require precise voltage control. Because motherboard designs vary widely, not all motherboards will use the AMS1117 chip.

If you need to determine whether your computer motherboard uses AMS1117, you can check the motherboard's technical manual or directly check the components on the motherboard. The AMS1117 typically has 8 pins and is packaged as SOT-223. Find such a chip on the motherboard and check its model number and mark, if it is printed with \"AMS1117\" or similar model number, then you can confirm its existence.

Before performing any operation related to the power supply of the motherboard, it is important to ensure that you understand the relevant electronics and take appropriate safety measures to avoid damage to the motherboard or other hardware.
Some computer motherboards have ams1117, some do not, most have, generally near the south bridge chip, some in the pc slot, it turns 5 volts into 3.3 volts to the south bridge or boot beryllium power supply.
