Thank you for your trust and sending me a help post. As for "major", I don't deserve it. I can only say that because I have more knowledge of computer hardware, my idea of computer collocation is more appropriate, and the performance of computer host is also ideal. Have rich practical experience in installation. Please note that I am a civil servant, not from the IT industry. Some netizens just think that I sell computers and want to ask the address of my shop and buy it home, hehe! My job is not mainly in the computer industry. Although I have mastered a lot of desktops and notebooks for office use ... I am familiar with the computer IT industry due to professional factors and know some shady things, especially the usual tricks of profiteers. ...
Because I often encounter many so-called experts and opinions questioning the configuration of my assembly machine, different concepts and different understandings of hardware, and there are fierce conflicts in the decision-making of configuration scheme, it is difficult for laymen to decide which side to go to and which to trust in such conflicts of opinion.
There are many phenomena that questioners don't choose themselves after exhausting their energy and finally satisfying their answers, and even have extreme cases of doubting their intentions, seriously distrusting themselves and making rude remarks. For the last extreme case, I just delete the answer and disappear. ...
Therefore, I will be very cautious when answering Baidu's questions for help, and I will not answer questions easily. The main reason is that I don't want to meet a person who doesn't understand computer hardware, but lacks the ability of objective and rational analysis, and is particularly rude. Recently, I have paid more attention to sending help posts directly to me and trusting my netizens.
Practice is the only criterion for testing truth. Everyone in China knows that. No amount of controversy is as good as the performance of actual installation and the comprehensive effect of quality, stability, energy saving and silence after long-term use. It is precisely because the computer mainframe is well assembled that many netizens will ask for help again after a year or two, asking for a new configuration scheme of the assembly machine, some for relatives and friends, some for an insufficient computer, and then add a new computer.
Super cost-effective, energy-saving and quiet, stable and reliable quality, three advantages are my basic position and outstanding characteristics in recommending the configuration of assembly machine. Pleasant super performance and unexpected affordable price are also the real sources for people to choose me as a satisfactory answer. I believe you will be very satisfied and happy. Especially in recent years, there are more and more users who use the same purpose as you, and the final installation performance is very satisfactory, which has achieved twice the result with half the effort. Some friends think that after spending thousands of dollars, the performance and efficiency are unbearable. After accidentally seeing that my answer was like yours, they sent me a help post. The final result of the installation is quite satisfactory and happy. At the same price, the performance is definitely different, and the degree of energy saving and mute is also different. These are real realities and lessons.
In fact, there are many people, especially the recent arguments in some hardware forums, which make me deeply feel that too many people are deeply poisoned by profiteers and misled by some irresponsible manufacturers' false propaganda. Their understanding of computer hardware is insufficient, one-sided or even completely wrong. Many installed computers are ridiculous, and even regard Ersanniu's products as first-class and first-class products as second-class products. The internet is full of various theoretical configurations that claim to be masters, but in fact, the price/performance ratio is extremely poor. Those who can't believe it, or they will pay a high price, especially if they are uncomfortable to use, and many people are very depressed about it. Especially the assembly machine configuration given by the computer city merchants, I have hardly seen the most cost-effective one. In fact, from the standpoint of a businessman, if he doesn't do that, he will have no profit at all, right?
However, profits should be based on honest management, and buyers and sellers are mutually beneficial, instead of deceiving customers like shoddy goods and extracting those huge profits from them. Naturally, it is a profiteer. Unfortunately, there are so many profiteers now. ...
I dare not say that the configuration I recommend is the best, but 99% is definitely the best for you, and the performance and quality will not let you down. At the current level of computer hardware development, the budget of 5,000 yuan is enough for CDR, AI, ID, PS, PDF, CDA, 3D, Office and other purposes. At present, the specific best choice is:
20 15 year summer 5000 yuan best cost-effective assembly machine scheme-"for professional drawing and graphic design"
Configuration list
Brand, model, quantity and unit price of accessories
CPU Intel Core i7 4790 × 1 1799
Radiator (buy a motherboard and get a B48 radiator for 79 yuan. It is suggested to add $99 (Kyushu Fengshen Xuan Bing 400).
Main board Gigabyte z97-hd3x1719.

Graphics (Core i7 4790 with Intel HD Graphics 4600)
Chassis Shadow Warrior × 1 ￥230
Gold medal of the first horse in strength 500 w× 1 279
Total price: ￥ 4,836
Without a discrete graphics card, you don't need a discrete graphics card for games, and you don't need to buy a professional graphics card from Lee Tae. No discrete graphics card, more energy-saving and ultra-quiet! Core i7 4790 integrates the display core of Intel HD graphics card 4600, which is enough for you. It is no problem to play some medium-sized and below games, such as most online games.
CDR, AI, ID, PS, PDF, CDA, 3D, OFFICE and other professional applications are highly dependent on CPU. As a new generation of four-core and eight-thread CPU, Core i7 4790 has outstanding performance-to-price ratio, and has super computing power for various professional drawing designs. Because 99.9% of tasks are completed by CPU, the importance of CPU occupies a key position in the whole machine. In such professional use, I3 and I5 are not strong, and AMD's eight nuclear products are not as good as Core i7. This is a recognized conclusion in the hardware industry, and it has also been supported by various professional hardware evaluation and user use results.
Core i7 4790 is not Intel's highest performance product at present, but it is the most cost-effective product in the installed capacity of less than 10,000 yuan. After all, the highest performance products have exceeded six or seven thousand yuan, and a CPU alone has exceeded your budget. Can I buy anything else? Ha ha! In short, since the CPU has decided, of course, the Z97 chipset motherboard with the highest specification and the best performance should be preferred from the motherboards supporting Core i7 4790.
As a high-end positioning, the Z97 chipset motherboard is currently quoted at more than 1,000 yuan. More than 2,000 ultra-luxury Z97 motherboards also abound. Compared with Gigabyte Z97-HD3 recommended by me, those motherboards with high prices naturally exceed several steps in terms of materials and supporting functions, but it is good to have enough. There is a huge difference between the presidential suite and 100 yuan, but if you just want to meet the needs of rest and have limited funds, you won't live in the presidential suite, will you?
Gigabyte Z97-HD3 is considered as a low-end shrink version by many experts. Strictly speaking, I have no objection to this view, but I think Gigabyte Z97-HD3 is good enough in the installed capacity of 4000-7000 yuan. If there is no reasonable collocation, the performance balance and budget allocation between hardware will be unscientific, and the cost performance of the whole assembly machine will be lost. What's more, Gigabyte Z97-HD3 is also the product of first-line manufacturers. Z97 has always been positioned at the high end, and it is also two grades higher than B85 motherboard. After all, Z97 can support DDR3 2400 memory, and B85 motherboard can only support DDR3 1600 memory at most.
As a super-standard brand-name classic, Kingston hacker beast DDR3 2400 has been sold at a very high price before May Day, with a single 8GB capacity above that of 600 yuan. However, after May Day, it has been avalanche-reduced to the present 380 yuan, which is not far from the 8GB DDR3 1600 in 320 yuan, so it is a very affordable and cost-effective choice.
Please note that you are equipped with two 8GB Kingston Beast DDR3 2400, that is, the total memory capacity is 16GB. Such a huge amount of memory can significantly improve the operational efficiency and response speed of professional design, which is also the key hardware foundation for large-scale CDR, AI, ID, PS, PDF, CDA, 3D, OFFICE, LR and other professional design and drawing tasks. Without this foundation, the smooth work of professional drawing and video editing will be impossible, and even it will crash when performing high-load tasks. Therefore, if a professional plotter only has 8GB of memory, it is a complete joke.
In addition, I also added professional Samsung MZ-7Ke128b/CN850Pro128g to the configuration. As a global leader in civil solid-state drives, Samsung has the manufacturing capability of solid-state drives with independent intellectual property rights, and its MZ-7Ke128B/CN850Pro128G is the latest flagship product of the company.
The development of Samsung SSD is very rapid. In just a few years, it has become a major SSD seller in South China and even the world. From the early days to the present, we have maintained the habit of releasing a new series of products every year. Following the well-known 830 series to 840 series, Samsung Electronics held the "20 14 Samsung SSD Global Summit" in Seoul at the end of 20 14. And released the company's next-generation 850 PRO solid state drive (SSD), which uses Samsung Electronics' cutting-edge 3D V-NAND flash memory technology and is listed in 53 countries and regions around the world, bringing a brand-new performance experience to SSD.
The brand-new 850 PRO SSD is based on Samsung's patented V-NAND technology and is suitable for high-end personal computers and workstations. Samsung's V-NAND flash memory adopts vertical cell structure, which not only breaks through the capacity limitation of traditional planar flash memory, but also greatly improves the reading and writing speed, durability and energy efficiency of the product. Solid-state hard disk also has the function of "dynamic heat dissipation protection", which can maintain a suitable ambient temperature during work and avoid data loss caused by overheating of the product.
Samsung's patented 32-layer 3D V-NAND technology can provide twice the density and writing speed of traditional 20nm planar NAND flash memory. Last year, Samsung's mass-produced 24-layer 3D V-NAND products for data centers performed well in the market. Now, Samsung has launched the world's first 3D V-NAND SSD for client PCs. By changing to a 32-layer columnar battery structure, more battery layers can be vertically stacked, thus increasing the density and reducing the carbon footprint. Therefore, 850 PRO can provide users with faster and more lasting performance.
Be careful not to buy the EVO series by mistake. EVO is a shrinking product launched by Samsung for low-end market competition. The difference between this product and the high-end PRO series is very obvious. Many businesses just use EVO to fool small white customers who don't know how to do it. Many people don't understand why 350 yuan's SSD with the same capacity 128GB is not cost-effective, while Samsung MZ-7ke128b/CN850Pro128G with 749 yuan is cost-effective.
Don't covet cheap SSD below 500 yuan. Users who covet cheap SSD around 350 yuan will regret it after most of the year. Why? If you are interested, you can search "Caton Hard Drive". Many people scoff at this. It was fine a few months ago, but the more you use the card, the worse it is than the mechanical hard disk. Bad luck will be bad after three months. I was really angry when I found out that I was passing the buck after sale. It was a big fire. It's strange not to scold, hehe!
As the host of game positioning, I will not recommend SSD to join, because SSD is not the key hardware to improve game performance. Low-priced SSD has a direct adverse threat to the stability of the whole machine, and the biggest harm is the stuck phenomenon and poor quality life. However, in the use of professional drawing design, the addition of professional high-end SSD will be very beneficial to the rapid completion of these professional tasks and greatly reduce the waiting time for data reading and writing. As the biggest feature of Samsung MZ-7ke128b/CN850 Pro128g, 3D V-NAND flash memory has the advantages of more than twice the capacity, twice the speed, ten times the service life and twice the energy consumption. Samsung claims that the particle life of 3D V-NAND MLC flash memory exceeds SLC! This is also the fundamental reason why low-priced SSD can't be compared with it at all.
Samsung mz-7ke128b/cn850pro128g, the most affordable price on a certain treasure is 658 yuan, but considering adding a 2.5-to-3.5 drive bracket to install the SSD in the chassis, most of the quotations are 729 yuan. Please note that I'm talking about iron and metal brackets, which are fixed with screws. You should be careful not to buy plastic brackets! The bad kind.
Ma Xian Gold 500W 80plus Certified Pure Gold Power Supply
Ma Xian Gold 500W, 80plus Gold Certified Active PFC Power Supply. This is one of the key hardware for the whole machine to save energy and mute. Be careful not to buy passive PFC power supply, which will not save so much energy, and at the same time, the heat output will be relatively large, so the noise will be great.
80 PLUS certification is a national energy-saving cash reward program issued by the US Energy Agency and implemented by Ecos consulting company. At first, in order to reduce energy consumption, system manufacturers were encouraged to use power supply with full load, 50% load, 20% load, efficiency above 80% and PF value above 0.9 under rated load conditions. The U.S. government pays out of its own pocket. For those who meet the above requirements, each desktop system will be rewarded with $5, and each server system will be rewarded with 10.
80Plus certification standard divides 80Plus into five standards: 80PLUS platinum, 80Plus gold, 80Plus silver, 80Plus bronze and 80plus white. Power supplies that meet different standards are awarded different certification medals.
80plus certification is divided into multiple levels, and the most basic one is white card, that is, the conversion efficiency above 20% load must exceed 80%. Then compare the white power supply with the ordinary power supply. Ordinary power supply is calculated according to the efficiency of 70%. Assuming that the power consumption of the main engine is always maintained at 200W, the power is turned on 10 hour a day, and the electricity fee is calculated at 70 cents a day, then the annual electricity fee is: ordinary power supply: 200 ÷ 0.7×10× 365 ÷1000× 0.7 = 729.
After one year, the difference between the two electricity charges is 9 1, which means that with white brand power supply, the power supply will be saved in about three years, and then it will be pure profit.
The higher the power consumption of the host, the more obvious the power saving effect of the 80plus power supply. In addition, 80plus power supply has the advantage of supporting 10-240 input voltage, which can cope with the problem of voltage instability in many areas. So it is worthwhile to buy 80plus certified power supply as much as possible.
For the gold medal power supply, the theoretical formula is: ordinary power supply: 200 ÷ 0.7×10× 365 ÷1000× 0.7 = 729.999 yuan; Gold medal power supply: 200 ÷ 0.87× 10× 368.
Save money from power supply faster with gold medal power supply. Moreover, the 80plus certified power supply has stronger and better protection ability for the computer host.
Of course, 80PLUS platinum brand power supply is the best. However, in order to reach that super-high standard, the requirements for design, manufacturing technology and materials are very high, resulting in high cost and extremely expensive price, which is basically not lower than 500 yuan RMB. At present, the price/performance ratio is not ideal, so it is good to buy a gold medal power supply. We don't have to pursue 80PLUS platinum brand power supply excessively if the installation budget is more than 10 thousand yuan.
Finally, the choice of chassis, Ma Xian Shadow Warrior's workmanship and appearance are excellent, fashionable and very modern, and the spacious space is very conducive to the long-term continuous high-load work of the whole machine. There are two colors: white and black. Most of the quotations are 199 yuan. 230 yuan is the price of giving away 1 or two front chassis cooling fans with the diameter of 12cm.
It is necessary to give away the cooling fan of the front chassis. The key point is what brand quality fan the seller gives away, which will increase the noise, and at the same time, the life is limited and the life is short. When it is limited, the noise will be considerable. If the choice is not good, don't blame me for boasting that this configuration is super quiet! Ha ha! That's not my fault.
Good chassis fans include TT Luna 12cm computer chassis cooling fans, but the more expensive one is 59 yuan. Therefore, you can ask the seller to give away at least the cooling fans of well-known brands whose prices are higher than those of 20 yuan, such as: Kyushu Fengshen Blade 12cm fan, overclocking three Qingfeng F- 123 12cm fan, Ma Xian Game Storm led 12cm fan and Cool Supreme Sickle led 12cm fan. Cheap fans below 20 yuan had better not be greedy. Those fans will increase the noise in less than half a year.
In addition, even if these famous chassis cooling fans are used, when they are just turned on in cold winter, there will be a lot of noise because the lubricating oil in the fans has not been preheated and restored to moisture. Don't say I'm bragging about being super quiet! Ha ha! Anyway, there won't be any noise if you keep turning for a while. Note that the diameter must not be less than 12cm fan! It is the mainstream cognition that the large-diameter fan with slow rotation speed has much less noise and large air volume is beneficial to heat dissipation. As for whether there are led lights, it doesn't matter, it just looks better.
Buy a motherboard and get a B48 radiator for 79 yuan. I suggest you add 99 dollars for Xuan Bing 400 and Xuan Bing 400. This is the so-called cooling artifact. They are high-quality and efficient CPU cooling fans, and their cooling performance far exceeds the original radiator of boxed CPU. Therefore, the origin of ultra-silent host came into being. In addition, the cooling fan of the above-mentioned gold medal power supply is also the key to mute, which has made the whole machine super quiet.
The main noise source of the computer host is the cooling fan, followed by the vibration caused by the operation of the hard disk and CD-ROM. Therefore, if the cooling fan is solved, two-thirds of the noise sources will be solved, and the vibration generated by the hard disk and optical drive during operation is actually extremely weak. The main sources of noise are poor quality of chassis and improper installation of chassis, and there are two reasons for chassis vibration. Therefore, you can't buy a cheap chassis within 100 yuan. Of course, you don't have to buy an expensive one from 300 to 500 yuan. For the vibration and noise caused by improper installation, it is necessary to add damping pads on the hard disk and CD-ROM drive, or adjust the installation position.
This configuration does not provide you with an optical drive, because it is not standard and not required by all users. After all, it is very rare to need an optical drive now. If you need a DVD burner, you can choose from all the major brands in the early days of 100. There is no need to ask me, because DVD burners have long been a product like Chinese cabbage, and there is no high-tech content at all. Just be careful not to buy miscellaneous brands.
Please continue to believe me, and don't go to the computer city to be induced and frightened by the merchants, and change and replace the hardware in my recommended scheme without authorization. If you have any questions, you can write to me at the station at any time and ask me directly.
Finally, I wish you a smooth purchase!
