The original P1 connector had 20 pins, why did the development of PCIe induce the adoption of a 24-pin P1 connector?
PCIe slots are faster than the previous generation and requires more power
The four new PCIe slots each require one extra pin on the P1 connector
To provide an additional 12 volts to the PCIe slots required by graphics cards
ATX specification 1.1 supports PCIe and calls for additional power requirements
