Many friends don't pay attention to power problems during the process of assembling computers, and they focus on the main components such as memory and processor. In fact, the power supply is absolutely important for the stable operation of the system. Now there are many types of power supplies on the market. How do you choose the power supply for the computer? How much is the power of the computer mainframe? How much is the power of the computer mainframe? The price of computer power in the market is between 100 yuan / 500 yuan / month, different brands, different power ratings, different models have different prices. How to choose the power of the host computer: The design of the power supply shell: the power supply shell can affect the shielding of electromagnetic waves and the heat dissipation of the power supply. The poor electromagnetic shielding effect will affect people's health. The poor heat dissipation effect will affect the life of the power supply and even the life of the hardware. Power cable and fan: In the wire selection of the power supply, the longer the wire is, the better. The longer the wire, the lower the conversion efficiency. Therefore, it is better to choose the power cable length. Also depends on whether the interface of the power cable is sufficient, so as not to affect the future upgrade. The internal components of the power supply: the power supply is not allowed to open, once it is opened, it loses the warranty, which also provides convenience for some manufacturers to do some trickiness. However, this does not stop us from observing the inside of the power supply. We can observe the internal electronic components through the vents of the power supply. So through the vents, which electronic components do we usually look at? The power supply is passive PFC or active PFC, it is recommended to choose the power supply with active PFC design. In fact, the passive PFC of the power supply is not bad. Because the passive PFC structure is simple and easy to manufacture, some bad manufacturers will make some thoughts on this, resulting in a decline in power quality. The active PFC production process is complicated, and under normal circumstances, there will be no counterfeit products. Another is to look at the power board, PCB board is best fireproof material, because manufacturers usually design the fuse on the PCB, which increases the risk factor of the PCB. Then look at the power cable to see if it uses 16 or 18 wire, because this wire has greater bearing capacity and is safer. How much is the power of the host computer, and how to choose the power supply of the host, we have already understood that the power supply on the market is very diverse, so everyone must choose a regular mall to buy when purchasing. Due to market changes, the specific price is subject to the official website quote.
