How to connect modular power supplies?

Question

Power Supply

I’m choosing a power supply with power for an 8 + 4 processor, with filters in many stores it’s hard, and I still can’t figure out how to visually distinguish the pci-e power connector from the cpu on the power supply. Suppose I found with the declared 8 + 4 + 4 corsair hx750i,

photo of connectors

Judging by the fact that the inscriptions UNDER the connectors to which they refer, for the processor and video card there will be only two of 8, then it is not clear what is in the second row. In general, I do not want to guess, please tell me how it works

Answer 1

Everything is done with "fool protection": each wire will stick only into the correct socket, both from the side of the PSU, and from the side of the motherboard and vidyuhi.
6-pin sockets for Molex and SATA, 8-pin sockets for vidyuhi and motherboard power supply, 24 pins in 2 connectors - and so it's clear.

Answer 2

Well, in addition to the processor and video card connectors with a motherboard, this model also has sata connectors (drives) and molex (internal peripherals). And it is worth noting that for a video card, the 8pin connector is disassembled into 6 + 2, and for the processor - 4 + 4.
