When you buy a computer power supply, be sure to pay attention to the following six power supply parameters, which can choose a high-quality power is very helpful oh ~ One, the weight of the power

If the CPU is a strong heart of the computer, then the power is its energy center. The power supply is not valued by the users in PC computer, but it is the product that is often neglected, but it provides stable and continuous current for all computer equipments, such as CPU, memory, optical drive and so on. If there is a problem with the

If the CPU is a strong heart of the computer, then the power is its energy center. Power in the PC computer is not the user's attention, but it is this often overlooked product, but for the CPU, memory, optical drive and other computer equipment to provide a stable, continuous current. If the power supply is out of the

Most servers are configured as 24-hour running devices. Therefore, server energy-saving technologies are more important than personal products such as PCs and laptops. Generally, there are two kinds of energy-saving technologies on servers. One is energy-saving technologies for processors, such as the Power Islands technology used by IBM on Power5, Intel's SpeedStep and AMD's PowerNow! The other is power

In the past, when purchasing computer accessories, the power supply was one of the most easily overlooked components. However, its various voltage output specifications, voltage stability, and protection in case of exceptions were very important, because the power required for all the accessories in the host must be supplied by the

Application of Integrated PWM controller MB3759 in Switching Power Supply [Date:] Source: Power Technology Author: Ma Xinxia song mingzhong Qian cunjian Cai fangwei [Font:Large Medium Small] 　 O IntroductionAs an energy-efficient power supply, switching

Stabilized Voltage Supply is an electronic device that provides stable AC power or DC power for the load. Including AC and DC regulated power supply.Necessity of using regulated power supply:With the rapid development of society, electricity equipment is growing day by day.

Overview With the development of science and technology, power electronic equipment and people's work, life, and the relationship between the increasingly close, and electronic equipment can not be separated from the reliable power supply, so the DC switching power supply b

The services currently provided by Internet cafes, such as web browsing, online games, online movies, distance education, and other basic services, are all related to the Internet, the quality of the network directly determines the viability of Internet cafes. Therefore, how to plan a high-quality network environment is a key point that Internet cafe operators must consider. Internet cafe Integrated Wiring accounts for a large proportion of the factors, mainly including:

Fault model: Gold Great Wall c-i5271-type display; Fault reason: lightning; Failure phenomenon: no display. Users reflect that the machine was struck by lightning, issued a "bang" a sound. Analysis and overhaul: Open the chassis found that the power fuse (f901/3.15a) has been burned, and the internal blackening, indicating that the power supply has a serious s

The current production of computer motherboards are using switching power supply mode. Switching power supply mode can be divided into: single-phase power supply, two-phase power

1-6. Switch Power Supply of excited TransformerThe transient control characteristics of the output voltage of the switch power supply and the load characteristics of the output voltage are relatively good. Therefore, the operation is relatively stable, and the output voltage is not prone to jitter, it is often used in

Offline Live detection Under normal circumstances, in standby state of ps-on and Pw-ok two power signals, one is high, the other is low level, plug 9 feet only output +5VSB voltage, as long as the meter to measure the voltage to the parameter value, you can determine the result of the problem. Artificial Wake power supply detection Use a thin wire (such as a p

The typical Ldo power supply itself consumes (vin-vout) *iout, so the larger the two, the greater the power consumption and the lower the efficiency.LDO, switching power supply DC's advantages and disadvantages (2008-11-06-22:40:23) Reprint Tags:

From: http://www.21ic.com/app/power/201206/126276.htm In a variety of past and present common power supply, switching power supply is very popular, generally can meet any design requirements. This kind of power

This article has three parts: CPU Main power supply circuit composition, CPU single-phase power supply circuit Working principle (take HIP6021 power IC as an example), the CPU single-phase power

In the last few installments, we have installed the main parts of the chassis, which will teach you the power source for installing your computer. One, from the appearance of recognition power supply Probably a lot of people know that the main power supplies are: at power

Internet cafes currently provide services, such as Web browsing, network games, online movies, distance education and other basic services are related to the network, the quality of the network directly determines the viability of Internet cafes. Therefore, how to plan a high-quality network environment, is an Internet café operators must consider a key point, the integrated wiring of Internet cafes accounted for a large number of factors, mainly two major parts:

Overview: The entire structure of an automobile is complex, with tens of thousands of parts. However, the basic structure of an automobile can be divided into four parts: Engine, chassis, body, and automotive electronics. The proportion of automotive electronics to total vehicle costs has been rising. Currently, automotive electronics accounts for 15%-30% of total vehicle costs. For some high-end vehicles, automotive electronics accounts for nearly 40%-50% of total costs. With the continuous dev
