Motherboard power supply problem, what does the motherboard power supply module mean

20+4 has 24 pins.

20 to the motherboard.

4 Give CPU or spare.

Power supplies are now designed like this! 20+4, so that the old motherboard can also be used normally!

Motherboard power supply module means that a power supply contains several module units with independent power supply functions. In practice, modular power supply comes from the category of servers, perhaps it may be said that only the service will use modular power supplies.

The so-called modular power supply refers to a power supply that contains several module units with independent power supply functions. In practice, modular power supply comes from the category of servers, perhaps it may be said that only the service will use modular power supplies. We know that the rubber orange service must run uninterrupted after it is turned on, because the power failure caused by negligence will inevitably cause losses.

Voltage regulation (power supply) module, referred to as VRM. Why it's so important. And how should I look at this when picking a motherboard? The VRM can be thought of as a small mini power supply, just like your actual host power supply puts 220V AC.

Rectified to 12V direct current.

The motherboard VRM is to reduce the voltage of 12V to more than one volt to provide 1 to 1 voltage for the CPU, in short, to provide the voltage required for the CPU to run. However, unlike the host power supply, the VRM is not as large and easily visible as the power supply, it is actually composed of several different components.

When buying a motherboard, don't underestimate the power supply problem, which is an element that affects the stability of the whole machine, and of course, it is also the most important factor we should consider when buying a motherboard.

At present, the frequency of mainstream processors is developing rapidly, and the frequency of Pentium 4 EE processors has reached the level of resistance, with an unprecedented typical energy consumption of 92W, and the power is expected to exceed the 110W mark. This leads to a sharp technical problem that needs to be solved urgently: the ultra-high power and the unenlarged core area, even with high-quality active cooling equipment, still cannot prevent the overall temperature of the system from rising significantly.

In this way, the three-phase power supply technology that has been on the motherboard for many years has already become overwhelmed, and the new four-phase power supply module can not only provide efficient and pure power supply for the processor, but also greatly reduce the overall temperature of the system by 8 10 degrees Celsius, which is a good thing for the motherboard full of various types of IC chips or the delicate and lovely processor. A safe motherboard, in addition to high-quality materials and fine workmanship, must also have efficient and mature voltage, temperature, wind rise rental fan sensor input and monitoring capabilities.

This raises a topic, why do you buy a motherboard and reserve so much room for upgrades? Absolutely unnecessary. Not to mention the new 800MHz front-side bus P4, high-performance dual-channel memory and SATA serial interface hard disk, even the development of the motherboard power supply system we couldn't talk about at that time, what "upgrade space"?

Therefore, when we buy a computer, as long as we pay attention to the integrity, security and rationality of the current set of configurations, it is enough to be happy.

The four-phase power module can provide pure power supply to the processor and can also significantly reduce the overall system temperature.

For the current mainstream motherboard products, two-phase power supply still occupies most of the market, and most second-tier manufacturers, and even the simplified version of the motherboard of first-tier manufacturers, use two-phase power supply. Here, there are not only reasons to control costs, but also two-phase power supply for most of the current processors to ensure stable use. For the average user, we don't feel the need to dwell too much on this issue, however, for those who are overclocking enthusiasts, as well as those who are ready to use the Intel Prescott CPU, the power supply of the motherboard must be considered in advance.
