Is there any way to judge whether a motherboard is good or bad?

The first thing you see when you get a motherboard is a variety of slots and interfaces. These slots are commonly known as plug-ins, and world-class motherboard manufacturers such as Intel, ASUS and other large manufacturers often use plug-ins made by Foxconn (FoxConn), from PCI sockets, mouse and keyboard interfaces to CPU bases, there will be Foxconn logos on them. Foxconn is also synonymous with good plugins.

PCB board. PCB is the printed circuit board, which is the board that is left after removing all the components from the motherboard table. In the early days, the PCB board was four layers, and now it is generally six or eight layers, and if it is a graphics card or memory, it can reach twelve layers.

The more layers, the stronger the anti-interference ability, but the more PCB layers, the better, if more, then the process is more complex, and the requirements for designers are higher. Therefore, the number of layers can only be used as a reference and does not play a leading role.

The color of the PCB doesn't matter, many server motherboards are green PCBs, but their stability should be well known to everyone.

Plug-ins. There are a bunch of slots or interfaces on the motherboard, collectively known as plug-ins, and first-class motherboard manufacturers will use plug-ins made by Foxconn, from PCI slots, mouse and keyboard interfaces to CPU bases, there will be Foxconn's logo "Foxconn".

Inductors, MOSFET transistors.

It is often said that motherboards have four-phase and six-phase power supply, which means the number of power phases that can be provided by the inductors around the CPU. You can count the number of inductors around the CPU, and high-end products may use 32-phase power supply.

The more phases there are, the more evenly balanced the load of each phase power supply line, the more stable the CPU will be able to work at a more stable voltage and current, and the operation of the computer will be more stable. In the past, the inductors were open, but now they are all changed to a cube, which is fully enclosed, which generates less heat and is more efficient.

MOSFETs are similar to transistors, distributed around the inductor, one inductor corresponds to 2 or 3 MOSFET transistors, the more corresponding the better.

capacitors, where the most corners are cut.

The most likely place for the motherboard to cut corners is the capacitor, the capacitor is used to ensure the stability of voltage and current, and filter out unfavorable clutter. Liquid capacitors fail after a while and then bulge, while solid states do not.

There are many kinds of solid-state capacitors, and the Japanese solid-state capacitors are the most famous, and the general solid-state capacitors have a relatively long life, high temperature resistance, and can work stably for about 50 years under the condition of about 100 degrees.

Wire routing. If your motherboard components are arranged in a messy manner and the wiring is very casual, it must be a very bad motherboard.

To judge the quality of the motherboard, we must first judge whether it has the phenomenon of burning, and secondly, it depends on its performance and memory size.
