This video divided into 3 Parts.
1) Essential Connectors
2) Power Connectors
3) Small Pins and Headers
Also, I discussed some concepts like Single channel, Dual Channel, PCIe, Motherboard, and Power Supply in short.
If you want to know those topics in detail. Here are the Detailed Videos.

Talking about the Esseicial connectors of the motherboard, there are 4 to 5 main essential slots present on the motherboard depending on what motherboard you are talking about.
The first slot is the CPU socket: We mount our Processors in this slot. There are 2 main types of slots are there.
LGA Socket and PGA Socket.
LGA Stands for Land Grid Array. and PGA stands for Pin Grid Array.
Both sockets have their own pros and cons.
A PGA socket is cheap to manufacture.
LGA sockets have a lot of advantages over PGA sockets.
LGA socket was able to provide a lot of pins, which allow processors to give you extra pins for additional connectivity which may be between CPU to PCIe, USB4, and many more. Also, LGA socket is capable to deliver more power to the CPU because of their strong connection and additional pins to divide that current.
Next Slot is RAM Slot.
CPU and RAM slots are connected directly with each other with some bunch of connections.
Some bunch of wires connects to one RAM slot and some connect to another RAM slot.
If you install only one stick of RAM, then RAM is sending and Receiving Data from only one Channel. Another Channel is kind of useless in that scenario.
If you want to utilize both of the Channels, you need to install Two RAM sticks so you can utilize both of the channels so your CPU can perform at optimum levels.
You may come with motherboards, which have Four RAM slots, but it is not necessary if they are having Four channels. The first One and Two RAM slots are shared with the First channel and the Third and fourth slots are shared with another channel.
If you install both of the RAMs in the same channel, you are still running on a single-channel memory configuration. So make sure you are installing RAMs on the dual channel.
Now let's dive into the PCIe slots.
PCIe slots come in different sizes like PCIe X1, PCIe X4, PCIe X8, and PCIe X16.
Where X1 means CPU and that port are connected with one physical lane.
What is Lane?
Answer: The combination of Two wires makes a Signal, and the Combination of Two Signals forms a Lane.
So, in PCIe X16 there are 16 Lanes allocated between the CPU and PCIe slot.
But all slots do not connect to the processor directly.
Please refer to this video: • PCIe Explained in Hind...
PCIe slots are backward compatible, you can install any generation of cards in any generation of PCIe slots.
Also, you can also install a PCIe X1 slot into PXIe X16 even if you have an Open-ended slot. Bandwidth limitations are a whole different discussion tough.
The next slot is M.2 Slot.
Technically M.2 slot is also a PCIe slot with a different form factor. Usually, M.2 Ports connect with the CPU with the Four lanes of PCIe.
Second Part of Video: Power Connectors.
Usually, all modern motherboards have Two different power connectors on the motherboard. One is the main motherboard power connector also called the 20+4 Pin power connector. Another power connector is the CPU power connector
20+4 pin power connector required to provide power to all the devices connected to motherboards like Low Powered Graphics Cards, CPU Fan, Chasis fans, pumps, and All USB Devices like except RAM and Processor.
To provide power to the RAM and processor motherboard have one more Power connector called the CPU power connector.
Different motherboards come with different numbers of Pins. The Basi motherboard comes with 4-pin power connectors, Midrange to Hignend motherboard comes with 8-pin power connectors, and some High-end Flagship motherboard comes with 2X 8 pin power connectors.
Third Part of Video: Pins and Headers.
Usually, cabinets come with 6 Different types of connectors and headers.
1. Front panel connectors. Responsible for the functioning of the Power button, reset button, Power LED, and OS Disk LED.
2. USB 2.0 Headers.
3. USB 3 Connector.
4. Front Panel Audio Headers.
5. Chasis Fans Connectors.
6. RGB or ARGB Headers.
All ports connect to the motherboard, refer to the pictures and Graphics Shown in the video to know better.
Also, motherboards have a COM header. known as Communication Port, which is used to connect to old COM mice and keyboards. Usually, those connectors can't be used by anyone nowadays.
Some motherboards have different proprietary ports. Like mine, ASRock motherboard has TPM header which used to be installed in ASRock's TPM Module.
ASUS has a lot of proprietary connectors, especially in their ROG motherboards.
So, those are the ports you can see in motherboards:)
