24 pins
the regular ATX has a 20 pin power connector, while the enhanced ATX power connector has 24 pin power connector.
== == 24-pins
ATX version 2.2 allowed for 24-pin P1 connector, which is backward compatible with the 20-pin P1 connector.

A regular ATX motherboard uses a single 20-pin P1 connector with optional 4-pin auxillary power connector

ATX Ver 1.0 has one 20 pin port ATX Ver 1.1 has one 20 pin port and a 4 pin port ATX Ver 2.0 has one 24 pin port and a 4 pin port
The panel involves a motherboard that is connected by pins to the FP connector. The motherboard uses a standard FP connector, therefore, easy to figure out.
The most common power supply connectors for motherboards will be either a 20 or 24 pin connector. Older unit used less pins like the ATX but the cure standard is the 20 or 24 pin main connector.
The expansion slot that requires extra power is the PCI Express (PCIe) slot. To accommodate the increased power demands of high-performance graphics cards, the PCIe standard added an additional 4 pins to the older 20-pin P1 power connector, creating the 24-pin ATX power connector. This modification allows the motherboard to supply more power to components like GPUs, which often require significant electricity for optimal performance.
BTX motherboards use a 24-pin power connector.
