Explanation

Pentium 4 processors required an additional dedicated 12V power connector beyond the standard ATX 20-pin motherboard connector. This connector is the 4-pin Molex ATX12V (P4) connector, which supplies supplemental 12V power specifically to the CPU. A replacement PSU must include this 4-pin connector, or the P4 system will fail to boot. The 20-pin main connector alone is insufficient for P4 systems, and the 6-pin connector is used for PCIe graphics cards, not CPU power.
