Hello,
I built a PC for the first time and I have some questions about the power supply.
I installed a Corsair RM650.
To connect the power supply to my motherboard, I used a large ATX 24-pin cable. However, on the end that plugs into the motherboard, there was one pin missing inside, as shown in the photo:

The end that connected to the power supply was "full."
The same goes for my graphics card: The PCI Express cable has two outputs (6+2 pins) with all the pins "full" on one side, both connected to my graphics card. On the other side, there’s just an eight-pin output, plugged into the power supply, where again there's a missing pin!
Is the cable defective or is this normal?
Another more general question, is there a direction for the power supply cables or not? For example, for the ATX 24-pin, the end that went to the motherboard was a 24-pin "unified," while the one on the power supply was 20+4.
Why is the missing pin on the PCIe cable on the power supply side, while for the 24-pin, it's on the motherboard side?
Thanks to everyone who reads this and, I hope, replies!

Hello
Unfounded worries.
There’s nothing abnormal.

I read it, thank you.
The ATX 24-pin connector, should the 20+4 be on the motherboard, on the power supply, or does it not matter?
Currently, the 24-pin is on the motherboard, and the 20+4 is on the power supply.

Sorry, I'm not sure I understand........
All power supplies are equipped with a splitable 20+4 pin connector to ensure compatibility with older motherboards that only had a 20 pin connector.
This connector is gradually disappearing in favor of a non-splittable 24 pin block.
If the motherboard has a 24 pin connector, you need to connect the 20+4 or 24 pin from the power supply to it.

Hello to you
Actually, I made a mistake; on the motherboard, it's a 24-pin block, but on the battery, there are two pieces, not even in 20+4 actually. My power supply is this one: http://i.pcworld.fr/1284745-corsair-rm650-2.jpg. The 24 pins are in 7+5!
On the graphics card, I had two 8-pin slots. In my power cables, I have one cable with an 8-pin on one end and two 6+2s on the other. Should I connect the 8-pin to the power supply side and connect the two 6+2s to the graphics card, or just the 8 to the graphics card (which will leave one slot empty) and the two 6+2s to my power supply (meaning two slots, knowing there are three, one of which is occupied by the cable going to the processor)?

It's a modular power supply, you need to check the manual provided with it.
The 8 pins on one side and 6+2 on the other are connectors called "PCI express" indeed for graphics cards.
The 8 side goes to the power supply, the 6+2 goes to the graphics card (as some have 6-pin or 8-pin connectors depending on the case).
