Do I need the 4 pin ATX cable to power the processor?

[Hunter_Lala]

So I'm building my first computer and I was looking at power supplies I saw mentions of the 4 pin ATX 12V cable. I know it brings power to the processor, but is it required for the pc to boot? Or does the processor get power directed to it from the motherboards power cable?

you need the cpu power connector to be plug in

Motherboards will either have a 4 pin or 8 pin power connector for the processor and a 24 pin for the motherboard and you must use both.
