The price of desktop computers is not too expensive, but in order to better ensure their performance and practicality, many people are going to own desktop computers by way of their own assembly, rather than buying desktop products. It is possible to assemble desktop computers on its own, and it is sufficient to know how to assemble them and to purchase the relevant accessories. Power is the main assembly component of desktop computers, and there are now various brands of desktop power in the market, but what is the price of desktop power more concerned?
What is the desktop power offer (price source network, for information only)
I: great wall mutiny master
Desktop power supply price: ¥238
The great wall's power supply, which is a well-known brand in the country's power supply, has, thanks to its outstanding performance, become the brand of our aerospace certification. The quality of the power they produce is assured by good quality, and the price of btx-400 sd desktop power is reasonable and a very good one. The great wall mutiny master, btx-400sd, was also packaged as green and green and environmentally friendly。
The overall power supply appears to be simple, generous and complementary to its green packaging. The power matrix is made of high-quality zinc-plating steel, with a 12-cm smart silent fan on the top, with a beehive on the side, and a silent heat spread. The wire and interface of the great wall's silent master btx-400 sd power supply is adequate, including one set of 20+4pin main power interfaces, one set of 4+4pin processors, one set of double 6pin video card power interfaces, three large 4pin-d interfaces and four sata power portals, which are sufficient to meet the requirements of the mainstream configuration for the application of power。
The horse is 450
Price of desktop power: 159
The sun shaft 450 is based on intel 2. 2 standard design and has more bright spots. Use servers, circuit boards, materials (2 ounce circuit boards), new circuit design with maximum conversion efficiency of 82 per cent, lp-7510 integrated control chips, built-in +3. 3v/+5v/+12v voltage overpressure, unpressure-protected circuits to ensure that power sources are able to protect power and other hardware in a timely manner under abnormal conditions of over-pressure and under-pressure; use lm393 dual circuit +12v cross-circuit protection chips to ensure that two circuits +12v do not burn other hardware because of excessive currents。
The quantico shape 450 rated 350w with a maximum power of 450w; the maximum currents of 12v at 10a, 15a, +5vsb at 2. 5a, 3. 3v and +5v at 22a and 21a respectively. After all, its fan turns at 1807 rpm, which, if satisfied, will be higher and the noise will increase. However, the price of the 450 desktop power supply for the first time was very high in terms of value for money。
How to select desktop power
I. Standarding
We are overwhelmed by the many desktop power brands in the market. So, j. P. Listed for you some of the country's more famous brands, aviation, the great wall, delta, conshur, all-china, shibuya, cold valley, which are pretty good brands. Of course, some of the second-line power brands, the tv-show twirl series, and jin hada are also trustworthy and cost-effective brands。
Ii. Watching engine
If you're just a brand-oriented guy, it's obvious that you're giving the bad guys a chance. Because each brand has a low and high end. In fact, the lower end of the first-line brand is not necessarily better than the middle end of the second-line product. You have to look at your computer configuration. In general, if it is an integrated graphic card computer, it is sufficient to install a rated power of about 200 w. 250w rated power can meet demand if it is accompanied by a generic independent graphic card. If the graphic card is an independent power supply and the processor is a high-end double core, then a rating of 280 to 300 w is sufficient. If the quadrupee belt is strong, it should be equipped with a rated power above 350 w. There are two things that need to be noted. First, power is generally understated, especially now that the rapist prefers to peak power. The second is to take the example of a four-band display card, which actually drives a computer, but when considering the need for a heavy load of future computers, it should be appropriate to rate 350 w, not to listen to the conspirator’s confusion about power supply, and ultimately to you。
Iii. Look at the weight
By weight, it is often possible to observe whether the power supply meets the specifications, and generally: good power casings typically use high quality steel, good quality, high quality, and therefore more heavy power, better materials. The parts inside the power supply, like transformers, dispersors, are just as heavy. The radiators used for good power sources should be aluminium and even copper, and the larger the heat, the better. The general radiators are combed, their teeth are deep, they are divided, they are thicker, and they have the better effect. Basically, it's hard to see the heat tablets without taking the power off, so the intuitive approach is to judge by weight. A good power supply typically increases the safety factor by adding elements, so the weight naturally increases. Poor quality power will save some of the capacitor and the wire, and the weight will be lighter。
You also have some idea of the price of desktop power, which is not fixed and is influenced by many factors. Since desktop power is mainly provided to computers in terms of capacity and power, it may also be responsible for other computer components, and it is necessary to purchase products from well-known brands. When desktop power is used, it may also have short circuits, faults, etc., which only formal products can protect。
