Motherboard
The board that physically connects every other component and defines what's compatible with what.
What is it?
The motherboard is the central circuit board that every other component connects to — CPU, RAM, storage, GPU, power, and peripherals all attach to it directly or indirectly.
What does it do?
It routes power and data between components, and its chipset determines which features (PCIe lanes, USB ports, overclocking support) are available.
Socket
A physical and electrical interface that only accepts CPUs designed for it. This is the first, hardest compatibility constraint in any build.
Chipset
Controls available features — how many M.2 slots, USB ports, and PCIe lanes you get, and whether overclocking is supported.
Form factor
ATX, Micro-ATX, and Mini-ITX describe physical size, which determines case compatibility and how much expansion room you have.
Socket
Must exactly match your CPU — there is no flexibility here.
RAM Support
Defines the maximum memory type, speed, and capacity you can install.
M.2 Slots
Sets how many fast NVMe drives you can install without adapters.
PCIe
Determines GPU and expansion card bandwidth and slot availability.
The motherboard is the compatibility backbone of a build — it constrains which CPU, RAM, storage, and case you can use, more than almost any other component.
A motherboard rarely adds raw performance itself, but a weak VRM (power delivery) can prevent a high-end CPU from sustaining its full boost clocks under load.
Common mistakes
- Buying a CPU and motherboard with mismatched sockets.
- Choosing a board with too few M.2 slots for planned storage.
- Overlooking VRM quality when pairing with a high-core, high-TDP CPU.
How to choose
- Start from your CPU's socket — it eliminates most of the decision immediately.
- Confirm the form factor fits your chosen case.
- Count the M.2 slots and PCIe lanes against your actual storage and expansion plans.
