How does a pcie card get its power?

A PCIe card receives its power through the PCIe slot it is inserted into on the motherboard, which provides a standard voltage of 3.3V. Additionally, more power-hungry cards, such as high-end graphics cards, may require additional power connectors from the power supply unit (PSU), which can provide extra power through 6-pin or 8-pin connectors. This combination ensures that the card has sufficient power to operate effectively.
