Purchasing Parts Inventory

Core components

①CPU: Generally, it is recommended to buy boards and U sets together, which can be cheaper. CPUs are only divided into boxes and loose pieces. Generally, loose pieces can be several hundred cheaper (partially affects warranty capabilities, please consult the seller). If the budget is insufficient, the premium for this box will be deducted first. , Wherever you buy the motherboard, you can buy the CPU. The CPU and the motherboard are one of the parts that are easy to overturn before the installation is completed. The warranty period of the CPU is generally 3 years, and the warranty period of the motherboard is generally 3 years. As long as the warranty is boxed, there is no difference. Try to ask for an invoice.

②Motherboard: Intel motherboards are mainly divided into three types: Z, B, and H. Generally, H is equipped with i3/i5, B is equipped with i5/i5k, and Z is equipped with i7/i9. If the budget is insufficient, the board U configuration can be downgraded. Asus MSI is the first choice for the motherboard, and the BIOS is relatively easy to use. The motherboard is one of the parts that is easy to overturn before the installation is completed, and it is generally not easy to break after installation. The motherboard should pay attention to the size of the motherboard (if it does not match the chassis, it will not fit in it), the CPU manufacturer (Intel and AMD), the memory type (DDR4/5, 4 mainstream, but turning to 5), and whether it has WiFi (recommended). The motherboard warranty period is generally 3 years, and the general brand joint warranty, try to ask for an invoice.

③Memory: The warranty period of memory is generally lifetime, which is a component that is not easy to break. The difference between good and bad memory is not obvious and it is not easy to test, and luck is a big factor.

④Solid state drive: most motherboards only have one direct M2, and the others are south bridges (but in most cases the difference is not obvious). Note that the M2 port is only a few generations of pciex. At present, the mainstream high-end solid state uses pcie4.0x4. Backward compatibility is supported, but the lower speed shall prevail. At present, the cost-effective solid-state capacity is 1T. Note that the premium of 2T is higher. Be careful not to buy QLC and solid-state products that are too miscellaneous. (At present, there are cost-effective solid-state products using domestic particles such as Damo and Jinbaida, which are given priority, followed by Changjiang and Samsung, and then Kioxia and Inruida. Samsung also has OEM vest disks starting with PM. For example, PM9A1 is Samsung 980Pro The OEM version, one 570 and one 800, but OEM generally only has store warranty)

⑤ Chassis, it is recommended to buy a large sales volume, many people use it, and it will be more comfortable in terms of installation and other aspects. Many things in the chassis have been done for you. Pay attention to the size of the graphics card and motherboard, as well as fan restrictions. The case is normally not damaged.

⑥ Heat dissipation, the i7 is water-cooled upwards and air-cooled downwards. The installation of water-cooling is actually simpler and more beautiful than air-cooling. For water-cooling, only Valkyrie water-cooling is recommended. The appearance, price and effect are all at the top level. Many Limin fc140s are used for air-cooling. Note that water cooling is the most dangerous part in the whole machine, and it is only recommended that JD.com operate it itself. (Generally, water cooling comes with its own fan, 360 is three 120 fans), and the cooling warranty period is generally 3-5 years.

⑦ Power supply, the power supply is only recommended for Zhenhua Haiyun, preferably JD.com’s self-operated, and of course their OEM products (such as ROG, Antec, and Chaser) should be as large as possible. A good power supply is convenient for future upgrades, and If there is a problem, generally only the power supply itself will be fried, and other components will not be affected. A poor power supply will cause problems such as electrical instability. The warranty period of the power supply is generally 8-12 years. The longer the warranty period, the more confident the manufacturer is and the lower the risk. It is recommended to start with gold certification.

⑧ Graphics card, now there are N cards, A cards and I cards. Note that the N cards before the 30 series, and the A cards before the 7000 series are all mining cards by default. Intel currently has no mining cards but the game optimization is weak. Generally, it is recommended to look at the price and buy after-sales. Most A cards do not support personal insurance, so it is not recommended to buy A cards from third-party stores. It is recommended that the graphics card account for 40~60% of the host price to achieve the best game performance.

non-core components

①Mechanical hard disk: It is only recommended to buy Hikvision’s Seagate and Western Digital OEM disks. Generally, the hard disk will have its own data cable (you need a power supply for the power supply cable). 4T is generally more cost-effective, but generally speaking, you can not buy a mechanical hard disk If there is no large data storage requirement)

②Display: The king of 4K cost-effectiveness is Ant Gaming and other monitors, which are currently around 2800, and 2K high-brush monitors are currently around 2000. This depends on your needs. Note that the table must be large enough.

③Earphones, stereos, cameras, microphones, WIFI and network cards: Unlike laptops, these things are generally not brought with them. The WiFi motherboard will have its own WiFi and wireless network card, and will additionally strengthen the signal for an external antenna.

④Fan: Some chassis, water-cooled and air-cooled will have their own fans, you can buy them extra, or you can save some fan money (or just fill the fan position, regardless of the lighting and fan strength)

the way of buying

Currently only these categories

JD self-operated
Jingdong non-self-operated
Taobao Tmall
Taobao Personal
pinduoduo store
pinduoduo shop
free fish

The best after-sales service is of course JD.com’s own operation, but please note that graphics card motherboards still need to be returned to the factory for repairs, so as long as these items can be personally guaranteed, you can directly find the brand.

Then, for Pinduoduo Taobao, you can buy whoever is cheaper. Pinduoduo can get various coupons through check-in/orchard/Duoduo video, etc. The common one is -100 coupons, so it is easy to crush Taobao in price but it takes a lot of money. some time. The main thing is to pay attention to the after-sales policy.

Install

If you don’t want to do it yourself, you can directly call the door-to-door installation service in Jingdong, Taobao and other places, usually only 1-300 yuan

If you want to install it yourself, please pay attention to take a good unpacking and installation video during the whole process, and then watch the hardware tea talk and Zhao Dezhu’s video installation

The step that is easy to damage is the motherboard into the chassis
The easy and time-consuming step is wiring

The pits I stepped on

I couldn’t find the mechanical hard disk cable (the main board case didn’t give it, and finally found that there was a short one in the box of the mechanical hard disk, which is enough)
There are several screws under the cooling vest when fixing the motherboard
The heat dissipation glue on the heat dissipation vest is not easy to pull off after it is pasted, and it will be deformed
When wiring, pay attention to the left and right sides of the power supply. The pcie and the CPU power supply of the motherboard need to be pulled far away, and they are relatively thick (it is very troublesome to perforate the wiring). Pay attention to the closeness of the CPU power supply line The power plug on the side of the motherboard, if it is plugged on the outside, it will cause the cable to be difficult to pull.
Don’t buy rgb ones if you have nothing to do, especially the rgb of the fan, it’s a lot of effort to connect it, I ended up being lazy and didn’t connect the rgb of the fan (mainly because I gave a hub, but I needed a sata power supply, I thought at first that there was no sata power supply, but later I found these are supplied with the power supply)
When installing the water-cooling fan, pay attention to the direction and the type of diagonal screws. I installed it backwards at the beginning, so I had to dismantle it and reinstall it.
