Many friends choose desktop power supplies using a "pretty much everything" approach, which carries great risks. Today's inspection will provide you with correct guidance on how to select suitable and excellent power sources based on parameters, and also provide beginners with a simple understanding; It won't involve many professional things. For some common professional terms, only simple explanations are provided for easy understanding. Baijian will provide you with detailed answers. The interpretation of the power supply nameplate is definitely based on the nameplate when purchasing a power supply. What is a nameplate? It's a sticker on the power supply that says various parameters. The following figure shows a typical power supply with a very standardized nameplate: generally speaking, a full voltage (capable of supporting both 110V from abroad and 220V from China) is definitely better than a 220VOLTY. The rated output power of 12V determines what configuration can be brought. For multi mechanical hard drives, attention should also be paid to 5V. However, this is also related to the power supply scheme, which will be explained later. Overall, when buying a power supply, the first thing to consider is 12V. As long as the rated output of 12V is greater than the maximum power of your CPU+graphics card, it means that this power supply can drive your computer. However, this can only indicate that it can drive, and other indicators are also important. Another thing to note on the nameplate is the maximum output power and rated output power. Rated output power (or real continuous load, meaning actual continuous load) refers to the ability to operate normally within this power range without any problems. The maximum output power refers to the maximum power that can be achieved in a short period of time. If your power supply is written with rated output or continuous load and is a large brand, then there is no problem within this value; If the maximum output power is indicated, it can be considered to choose a higher power source for calculation. Perhaps some friends have heard of the saying 'choosing a power supply for only 1 yuan is enough to buy 1 watt', which may sound fine at first glance, but in reality, it is still not rigorous. For beginners, if the nameplate of a power supply has any missing labels in items 3-6 (such as multi channel+12V not labeled+12V combined output power) or disorderly labels (such as not labeled with rated, only labeled with PEAK peak), then such a power supply can directly PASS out
