It's very simple, just pay attention to anti-static and touch it with a metal object connected to the earth before installation.

1. The harm of inferior power supply.
According to statistics, more than 50% of a computer's hardware failures are caused by the power supply. Poor power supply quality can make the computer unstable at least and cause the accessories to burn out. The importance of power is equivalent to the "heart" of the human body, which is the source of power for computers.
2. Differences in EMI filter circuits.
EMI circuits for high-quality power supplies) (low-quality power supplies do not have EMI circuits).
The EMI circuit is mainly used to filter out high-frequency clutter in the power grid and prevent the radiation inside the power supply from leaking out of the power supply. Without EMI circuit, it will affect the normal use of the computer.
3. Differences in high-voltage filter capacitance.
High-quality power supply materials are sufficient) (second-hand materials are commonly used for inferior power supplies).
If the high-voltage filter capacitor is poor, the low-voltage output will be unstable, and the ripple will also exceed the standard, which will lead to the instability of the computer and the burning of the accessories.
4. Differences in transformers.
A good quality power transformer is tall) (a bad quality power transformer is short).
The height of the transformer reflects the maximum power output of the power supply, and the higher the height, the greater the power. The transformers used in inferior power supplies are low.
5. Differences in low-voltage filter rectifier circuits.
Good quality power supply) (poor quality power supply).
If the materials of the low-voltage filter rectifier circuit are insufficient, the fluctuation of the output low-voltage direct current will be very large, and it contains a lot of clutter, which will lead to the instability of the computer and the burning of accessories.

1. Motherboard: The motherboard is a rectangular circuit board with some important circuits for some equipment such as CPU, sound card, graphics card, hard disk, memory, etc. The motherboard selection is recommended for GIGABYTE motherboards B250 series.
2. Graphics card: It is a display card, which is a major component of the computer host, which is responsible for making the data in the computer appear through the image, it assists the CPU to work, and has the ability to process images. The graphics card is recommended for the NVIDIA GTX1050 series, and the GTX1070 or GTX1080 series can be considered for those with a high budget.
3. Hard disk: store all computer data, divided into mechanical hard disk and solid state disk, mechanical hard disk read and write rate is much faster than solid state disk, generally we choose 120G or 240G mechanical hard disk and then install Seagate 1TB hard disk. If the memory requirements are not too high, installing a mechanical hard disk will do.
4. Memory: It is mainly to let the program stored on the hard disk play a role through the memory, for the memory module, we can usually install an 8GDDR4 memory module, or you can install a memory module.
5. Power supply: It is the key to start each accessory of the computer, and the power supply is selected according to the power of the accessories. Generally, we choose a power supply with a rated power of 400W and a peak of 500W.

Although some of the budget is over-budgeted,But no matter how low it is, it can only be reduced in the brand or choose dual-core,I believe that people who buy computers now understand that some are not bad at this point of money, choose a four-core good quality brand, hehe, I hope it will help you。
This morning, I went to my brother's house to play. There are two vases in front of the door of his house. The vase is very beautiful, one is engraved with a dragon and the other is engraved with a phoenix, and the flowers inside also exude a fragrance that is intoxicating. I went to my brother's house and admired it for a while before I walked in to play with him. >>>More
Explain it to him directly, it's not your fault that you don't like him, it's impossible to drag it out like this! It's not good for him, and I believe that there is no one in this world who can't think of it. A little damage in this situation is inevitable. >>>More
lol is a little better.,The picture is very good.,There are many modes.,The system is distinctive.。 Hero props or something can also be bought with game currency.,It's as fun as it doesn't cost money.,League of Legends is recommended.,You can try it.。。 Hope..
What you have to look at in the interview, the job, the candidate's body shape, appearance, complexion, clothing and demeanor, mental state, etc. Positions such as national civil servants, teachers, public relations personnel, and enterprise managers have higher requirements for appearance and demeanor. Studies have shown that people with dignified appearance, neat clothing, and civilized manners generally do things regularly, pay attention to self-restraint, and have a strong sense of responsibility. >>>More
