Don’t want to be a pick-up man? This purchase of computer hardware small Tips you are worth collecting!

In June, I received a request from a classmate who was involved in the game. I wanted to install a main game console with a budget of more than $1500. As long as the host does not use the monitor, and then through my round of bombardment rounds of bombing, “success” will add the budget to $1500, with the arrival of the accessories one by one, Aru wants to share with you how to identify and avoid I bought second-hand computer hardware. After all, I use too many parties now. There are no reason to return them and everyone is forced to become a pick-up man. This phenomenon is really disgusting!

The accessories used in this installation are correct. Now the host of the i5+GTX1060 is also close to the $1500 price. It is terrible. The price of this $1500 is still based on the purchase of the main accessories in EBAY, while the power supply, headset, solid state drive , and chassis are based on the transfer of my inventory to him.

The power I originally purchased is a white card 500w power supply of HUNTKEY. I just didn’t understand it when I installed it. I only know that I saw this power supply 500w, it is not expensive. I usually buy $30 when I bought it, so I decided to buy it.

It is. The result didn’t take long. This power supply exposed a big problem. The noise was huge. When the game was running, it would emit a very obvious fan sound, and I don’t know if there is a current sound for the power supply of the video card. I used to think that it was the noise of the CPU fan. Later, after changing the fan, I found that the noise did not change. Listening carefully to the sound source is from the power supply position. This is sure that this power supply is black. It’s okay to wear headphones in the winter. It’s too hot in the summer. I usually use the sound in the game. The fan noise becomes unbearable, so I decided to change the power of the computer to temporarily improve my experience.

Minefield of computer hardware – Yeston 250G solid state drive

Reason for purchase

At present, the price of solid state can be said to be much lower than the price of the previous two years. Of course, the solid-state market is also a mixed market. There are many manufacturers and many models. A few days ago, the Yeston Express version of the SSD, the price is $30, but after some experience, I also recommend that you do not buy this solid state drive, a little thunder.

Computer hardware evaluation article 2: dual-band wireless good companion, Fenwei AC8265 notebook wireless network card evaluation

For laptops, the advantage of wireless Internet access is that you can use the wireless network to connect to the Internet without connecting a network cable, but it is an important role for wireless network cards, such as wireless Internet access and Bluetooth connection, so I am in the Tmall Mall. The flagship store purchased the AC8265 dual-band wireless network card. Today I will introduce the evaluation of this Fenvi AC8265 notebook wireless network card. And my father’s computer host needs to replace the wireless network card.

Fenwei AC8265 notebook wireless network card is a dual-band notebook wireless network card developed by Shenzhen Fenwei Technology Co., Ltd., model is Intel (Intel) 8265NGW, the interface uses M.2 PCIe 2230 specifications, and is universal for various brands.

Computer hardware evaluation article three: Gigabyte Brix mini host installed SSD, install Windows 10 operating system, Samsung 860EVO mSATA 250GB solid state hard drive evaluation

There are a lot of problems with the computer, such as slow reading and writing speed of the hard disk, slowing down the card, slow loading of the game, etc. Many people have upgraded or installed the solid state hard disk for their own computer. The solid state hard disk has faster reading and writing speed. I have a Gigabyte Brix mini host in my hand that needs to install a solid state drive as a system disk. Someone asked me why I installed a solid state drive. The first time I bought the first laptop was the Lenovo U410 in June 2013. Later I found the SSD after disassembling myself. Unfortunately, the SSD with a capacity of only 24GB is mainly used as a cache for the mechanical hard disk. The equivalent of Intel AoTeng memory to the mechanical hard disk acceleration, and later sent to the after-sales upgrade SSD found that the solid state drive is mSATA interface, until the official release of Windows 10 in 2015, I use the Lenovo u410 laptop because it does not support Windows 10 The reason, I had to buy the Gigabyte Brix GB-BXi7H-5500 mini host, I carefully found that the interface is also mSATA interface, also supports the installation of mSATA solid state drive, so I decided to buy a Samsung 860EVO mSATA 250GB solid state drive to Gigabyte Brix mini host Use, the original use of Transcend TS256GMSA370 mSATA 256GB solid state drive, it took less than 3 years to break.

This is the Samsung 860EVO mSATA 250GB solid state drive, with a new packaging, capacity of 250GB ~ ​​1TB. At the same time, the flash memory adopts Samsung 64-layer 3D TLC V-NAND. The main control adopts its own MJX controller, and the cache is Samsung 512MB low-power DDR4 cache. The read/write speed is 550MB/s and the writing speed is 520MB/s. 3D V-NAND technology, outstanding performance, durable, safe and reliable.

MAC Computer Hardware & System Installation Tutorial Sharing: Save Apple White A1342

As the saying goes, art does not press. This is not a lot of leisure time recently. I saw that the Apple computer used at home is not smooth. I don’t want to watch a movie, let alone watch the movie. So the subject begins to learn how to disassemble the apple. Computer, how to install Mac system.

Before I read the modified article of Dell’s notebook computer written by the main character , it is relatively simple to learn to install the win system. There is not much skill. There are mature software tools for making USB flash drives, for example, computer store U boot disk making tools, Chinese cabbage, old peaches, etc., the mirror version and the original version of the system downloads are also more. Therefore, it is very easy to install the system.

In this and the first two articles, the disassembly and assembly steps are not much different. The difference is that the internal structure and frame of the computer are different, and the disassembly skills and disassembly should be very different.

Past experience

Talk about the first contact with SSD ( Solid State Drive ), which was the first laptop I installed in my life. At the time, when I bought it, I thought it was used for office work. It cost only 2,700 yuan, and the processor is castrated. Version (i3 low-voltage version), there is no separate graphics card, the hard disk is a mechanical hard disk . At the beginning of the installation of the win7 system, the boot speed is not the focus of my attention, the focus is on typing chat, brush the web page, open the speed and smoothness of the commonly used software, start photoshop to repair a photo or something, the experience is not good . After planting the solid-state hard drive in my heart, I thought about waiting for the head to be wide and the whole one to be installed. Time is up to 15 years (14 years of New Year’s Day to buy a computer), from Jingdong bought Transcend solid state hard drive and miscellaneous CD drive frame, according to the tutorial article, disassembly, installation, writing system, installation driver, step by step operation, the whole process smoothly. That Dell computer, the installed SSD is Transcend’s 120G, and now the price has soared.

It seems that Moore’s Law seems to have a little internal force here, but the optical drive is cheaper.

Prepare for work

Back to the theme, today’s protagonist is Apple Computer White, the specific model is: A1342, disassemble the optical drive, you need to prepare materials before installing the solid state drive:

1. Screwdriver gadget;

2.2.5 inch 120G solid state drive;

3.9.5 mm thick optical drive frame;

One U disk of 4.16G capacity or more;

5.win system PC;

6. Software UltraISO.

Material preparation instructions:

1. Screwdriver gadgets are recommended to buy tweezers when you buy them. The small screws in your notebook are very small and easy to fall into the corners. It is much more convenient to have tweezers.

2. SSDs are divided into original granules, of course, the price is more expensive, if not bad money directly on the original granules of the big brand manufacturers. Of course, if you are like me, if you trust the services of JD.com, you can also consider choosing a cost-effective 120G SSD.

3. The optical drive frame has 9.5 mm, and also has a 12.5 mm thick optical drive frame. This mainly depends on the specific configuration of your laptop. As for which thickness to choose, you can remove your laptop drive before purchasing, using the ruler. One amount, to avoid buying the wrong.

4. U disk capacity is at least 16G, USB3.0 is the best, reading and writing speed is fast, the main U disk is using Flash Di 32G USB2.0, the read and write speed is slow.

5. PC can be used for desktop or laptop computers, mainly for making MAC boot disks. I will briefly explain about the startup disk of the MAC computer. There are many tutorials on the Internet. You can choose different tutorials according to the specific model of the computer. In fact, the general steps are the same, there is not much difference.

5.UltraISO floppy disk is a CD image file creation / editing / conversion tool, online to find the official website to download just fine, after the installation is complete, use the trial version.

Can the chassis power supply be purchased at will? Of course not, why? In addition to the choice of your own computer hardware configuration, but also consider the space size of the chassis power supply, so as not to be able to properly install due to the excessive power supply volume, once purchased 750W power supply because of the length of the problem can only replace the chassis installation use.

In the purchase of power supply, in addition to focusing on brand and quality assurance, it is natural to give priority to the full module power supply. First, basically this type of power supply is 80PLUS certified. The typical load conversion rate is higher than that of ordinary power supply, which is energy saving. Part two; the second is to match the module line on the line more free and convenient, easy to manage and save internal space; third, you can change the line as needed, providing more convenience and practicality for DIY players.
