Not everyone can buy new hardware (especially some student friends), so this part of our friends will turn their attention to the second-hand hardware market. The second-hand hardware is increasingly received by its universal practicality and low prices. The favor of enthusiasts. The second-hand hardware is divided into: new goods, semi-new goods, old goods. The channels of purchase can be divided into: foreign imported elimination, organ units, or large company's recycling. Different purchase channels have varying degrees of products. At the same time, you have to take a certain risk while purchasing used hardware. How can I buy a second-hand hardware that has been satisfactory? The author introduces you for nearly three years of hardware purchase experience and experience. I hope to play a role in purchasing used hardware. Second-hand hardware which accessories are not worth buying second-hand hardware, the least worth buying, is a display, know why? The author purchased the second-hand hardware for nearly three years. I used to see the technical personnel in the second-hand hardware market. I have made the second-hand display (mostly bad), after the seven fights, I will make it again and again, and I will have a cold. After a few hours, you can sell it if you have no problem. Such a display will take long for a long time. There is a variety of problems with different degrees of displays, focusing, and mixing ... and so on. It looks fine when you purchase everything. But how long it will have a variety of problems. In general, the shorter the product technology indicators, the better performance, the better performance, but the current color display is from abroad, and it is some older products, which does not meet the indicators. And environmental protection requirements and radiation is quite high. Even if you buy a display, you should measure your health or money is important. The eyes are the windows of the main spirit, please think twice. The optical drive is also one of the second-hand hardware is not worth buying. Now there is a lot of DIRER to say the optical drive into a consumable, the frequency of use of the optical drive is high, the life of the optical drive is not long, plus second-hand things in the transportation process. Bumping, causing the laser head shift and the ability to read the disk is significantly decreased, and the quality is uneven. Both the old birds know that the transmission of the high laser head can improve the performance. If the second-hand hardware business has a CD-ROM drive that is in a well-behaved performance, he takes the highlights of the laser header to improve the performance of the reading, and on the spot Give you a demonstration, when you read the disk, you will not be bad. If you buy this type of optical drive that taking a high laser header transmit power to improve the performance of the disk, I believe how long will I say to you. Due to the popularity of DVD, the price of the optical drive has been low, and now I can buy a mainstream brand drive. Don't need to save money to take such a big risk, this can't come, unless your luck is particularly good. Second-hand hardware which accessories worth buying second-hand motherboards can be said to be a second-hand accessory of cost-effective. When purchasing, the second-hand motherboard needs to be combined with related accessories. First, look at what chipset is the chipset, the main board performance of the chip is large: including supporting different types of CPUs, different data transfer rates, etc., and then determined according to their own needs. At the time of purchase of the second-hand motherboard, you should test one by one: PCI, ISA, AGP, DIMM and other sockets, IDE, USB, COM and other interfaces. After the test is good, buy it, because if these slots or interfaces have a problem, it will cause the relevant accessories that cannot be used. Finally, look at whether various slots and interfaces are enough. The principle of purchasing the second-hand motherboard is: carefully take a test one by one. At this moment, I recommend buying second-hand keyboards and mice, why do you want this? Because many keyboards and mouses in the second-hand hardware market are recycled from the server. The server is almost rarely used to use the keyboard and mouse, and their usage frequency is very low, plus the keyboard and mouse with the server are imported in foreign countries. Such as 3Com, IBM, etc., such keyboards and mouse quality are quite good. Many friends who know each other like to buy such keyboards and mice, not willing to buy one or two hundred new.
