How to choose a power supply when equipping a computer?

More and more friends choose to configure computers by DIY, which is low-cost on the one hand, and can configure different models according to specific needs on the other hand. When choosing accessories, most people pay more attention to accessories such as CPU, hard disk, memory, motherboard, etc. However, accessories such as power supply that are ignored by everyone may be more worthy of attention by enthusiasts, because it involves the stability of the whole machine operation. If a computer has a problem with the power supply, it is likely to cause the whole machine to be paralyzed, and frequent crashes and restarts due to power failures are not uncommon. We have reason to devote more energy to the choice of power supply.

At present, the products on the market are of varying quality, and it is difficult for ordinary people to distinguish them. After all, some of the DIYs are not experts. Moreover, most people pay too much attention to accessories such as CPU, hard disk, motherboard, etc., and often turn a blind eye to the power supply. Therefore, it is necessary for us to introduce some relevant knowledge about power supply to help everyone choose better products when matching computers.

I would like to take two products under AOC Technology Group (AOC) as an example to illustrate the problem. AOC has two good products, one is the Cooling King 400 Diamond Edition, and the other is the Cooling King 330 Special Edition. These two products are representative, after all, one is relatively high-end and the other is relatively low-end. Both products

require an AC input voltage of 170VAC-270VAC. Such a wide voltage input provides conditions for their stable operation. So what about power? The rated power of these two products reaches 300W and 230W respectively, providing different power outputs for different configurations, and the OPP power, that is, the peak power, is 400W and 330W respectively, which is 100W higher than the rated power. In general, such a design can better meet the actual needs of users, because there is a large range from rated power to peak power, which can cover most of the needs of users. At the same time, the peak power is 100W higher than the rated power, which also provides conditions for its safe operation, because once this power is exceeded, the power supply will be automatically cut off, thus playing a protective role.


In terms of platform support, both products support the full range of products including INTEL Pentium 4, AMD Athlon XP, Sempron, Athlon64 X2, CORE 4 QUAD, etc. We know that the working condition of the power supply will directly affect the working condition of the CPU, and these two products also have sufficient support for high-performance CPUs, which makes users with different needs feel at ease. On the other hand, considering that the CPU has higher requirements for heat dissipation, DIY enthusiasts should know how heavy the fan on the top of the CPU is. Of course, since it claims to be the "king of heat dissipation", let's take a look at the fans of its brothers. Both products are 12cm hydraulic guide patented fans, which can achieve a good heat dissipation and cooling effect, and are also dust-proof and silent, which ensures that its lifespan is often much longer than that of general products.

In terms of stability, it has passed the 3C certification and has six protection functions, including overvoltage, undervoltage, overcurrent, overpower, overtemperature, short circuit, etc. Therefore, no matter how luxurious and powerful your configuration is, you cannot escape the scope of its protection function, which gives users another sense of security. This sense of security is also reflected in the after-sales service. The one-year replacement and two-year warranty after-sales service (three-year warranty) make you not have to worry about after-sales. In fact, under normal circumstances, as long as it is used normally, such products will hardly have any faults.

Both products have rich output terminals, wide output voltage, minimum output current, maximum output current, etc. It should be said that while meeting the requirements of good heat dissipation, it also highlights its wide compatibility. Whether for high-end or low-end models, such power supplies should be the only choice for DIY enthusiasts.
