wholesale jewelry gold and silver What is the essential difference between computer power supply ATX2.0 and 2.31 version 2.31

wholesale 925 sterling silver jewelry india According to the standard of Intel, the computer power supply is now divided into three power supply standards: ATX 12V 2.0, 2.2, and 2.3. "Theoretical support".

This output of double -road output -TX12V 2.0 standard

is the fastest year of PC hardware transformation, the fastest acceleration, of which users pay the most attention to the graphics card interface From AGP 8 × "Promote" to PCI-E × 16. After the new standard was released, ATI and NVIDIA followed Intel's pace to launch high-performance PCI-E × 16 interface graphics cards. For a time, multi-pipelines and large memory became the topic of DIY players. However, while users enjoy high -performance hardware, problems such as high power consumption and high incidence also followed. Players who upgraded the old power supply began to encounter "dream" class failures such as blue screen, crash, restart. The reason is caused by insufficient power supply. To this end, with the successive listing of the PCI-E interface motherboard, Intel officially launched the ATX12V 2.0 power standard.

ATX12V 2.0 standard is a type of ATX power specification. In essence, the ATX12V 2.0 standard is formulated to solve the problem of the rapid "expansion" of CPU power consumption. Compared with the ATX12V 1.3 standard, the most obvious improvement of the ATX12V 2.0 standard is to use dual -road 12V output design. 12V1DC Power supply to the motherboard and PCI-E × 16 graphics card through the power main interface (12 × 2) to meet the current required for the stable operation of the graphics card and DDR2 memory. In the motherboard wiring, 12V1DC and 12V2DC are also completely separated, and the main power interface is changed from the original 20Pin to 24Pin output.

. In addition, another important improvement of the ATX12V 2.0 standard is that the conversion efficiency has increased. The conversion efficiency is the ratio of the output power to the input power. The ATX12V 1.3 standard stipulates that the minimum conversion efficiency under the full load of the power supply is 68%, and the 2.0 standard will increase the conversion efficiency to 80%, which will make full use of energy. Do not underestimate the parameter of conversion efficiency. In addition to making the numerical improvement, in addition to making the power supply more green and environmentally friendly, saving electricity, the proportion of remaining electricity is also small. That is, the heat generated by the ATX12V 2.0 standard power supply unit is less than the ATX12V 1.3 standard power supply during the operation time, which has a vital impact on power supply heat dissipation and the service life of components.

During the vigorous development of the ATX12V 2.0 standard, Intel "planned" a total of four power specifications, namely the ATX12V 2.0 standard 250W, ATX12V 2.0 standard 300W, ATX12V 2.0 standard 350W and ATX12V 2.0 standard 400W, this this, this, this, this, this, this, this, this, this is 400W. This is 400W. This is 400W. The standards of the four levels of standards 12VDC output must reach 22A.

Although it has been announced for more than two years, there are still many ATX2.0 or even ATX1.3 standard power supply in the market. Power 200W -300W grade. These power supply is suitable for single -core processors and integrates the main board to form an entry -level entertainment and dormitory platform. The price is affordable and the performance is completely sufficient. In addition, users who installed the machine 2 years ago were mostly the supply of the matching at that time, and the power was not more than 300W. Therefore, when upgrading the system, it is not a big problem to choose hardware such as single -core CPU and 7300GT. However, if you use products such as dual -core CPU and 7900GS, the system will be overwhelmed due to the surge in power consumption.

It support dual -core green environmental protection -TX12V 2.2 standard

In early 2006, Intel will significantly cut the price of its PentiumD dual -core processor, a "bred" for half a year The dual -core popular storm officially kicked off. At the same time, Intel once again updated its "proud" ATX12V power standard, and the new ATX12V 2.2 standard comprehensively optimized the dual -core processor.

Compared with the ATX12V 2.0 standard released a year ago, the ATX12V 2.2 standard has new requirements in terms of maximum output power, current characteristics of various roads, and conversion efficiency.

In order to adapt to the rapid improvement of dual -core platforms in the main frequency of CPU, graphics card performance, memory, hard disk capacity, etc., Intel added 450W output specifications to the ATX12V 2.2 standard, and gives a load cross chart for reference Essence In this way, for users who use dual -core SLI platforms, even if the 7900GS graphics card is used for dual -card interconnection, the 450W rated power power supply is sufficient to cope.

In terms of current output characteristics, the new 2.2 standard does not improve the current capacity of 12V, and the instead decreases, but it has greatly improved the instantaneous output capacity of 12V current. The reason why the new standards have changed is that Intel considers that with the continuous improvement of the process and process, the mainstream dual -core and even multi -core processors may not have a growth trend in terms of overall power consumption, but these processors need to be higher at the moment of startup. Current supply. Therefore, in order to operate the system stable, the current peak of 12V output needs to be increased. In addition, the 2.2 standard has increased the output current of 3.3V and 5V to adapt to the power supply demand for SATA hard disks and optical drive equipment that has been continuously improved.

In terms of conversion efficiency, the new ATX12V 2.2 standard still requires the conversion efficiency of 80 %, and the execution is more in place than the 2.0 standard. Currently in the United States, some institutions (including Intel) have required computer manufacturers to adopt power products with ATX12V 2.2 standards and energy consumption conversion efficiency of 80 %. As a "return", they will give reinforcement such as channel policy to achieve the "long -term" purpose of improving green energy -saving computer output.

ATX2.2 Standard power supply is a necessary configuration for the current purchase of dual -core hosts. Generally, 350W -400W -grade products can easily cope with mid -to -high -end game platforms such as Core 2 X1950pro to make the basic "power" foundation for the system overclocking of the system overclocking Essence Due to the relatively high default power of the ATX2.2 standard, if you buy 400W and above products, even if you pay the high -frequency dual -core processor G8600GTS, the "next -generation" configuration is completely feasible. Therefore, if you have the opportunity to choose the ATX2.2 standard power supply recently, then buying a product with a large power will not "regret".

The height with "single" and "double" worry -Worry -TX12V 2.3 standard
n on April 3, 2007, Intel released the latest ATX12V 2.3 standard, "silence" " The long -term power specifications have been upgraded again. This time Intel released the 2.3 standard, mainly for the hardware upgrade brought by the Vista system and the power consumption of dual -core and multi -core processors.

The low -end users have no longer purchased independent graphics cards as the necessary choice for the first installation due to the continuous improvement of the performance of integrating chipsets. Therefore, there are some "large and small uses" in the purchase of dual -road power products. In the ATX12V 2.3 standard this time, Intel launched the three power levels of 180W, 220W, and 270W, which provides an economical product solution for entry -level users.

In addition, in terms of high -power power supply, 300W, 350W, 400W, and 450W power level given by the ATX12V 2.3 standard are "born" to support high -end Vista graphics cards. And compared with 2.2 standards, the 12V1 output capacity in the 2.3 standard has been improved, and the 12V2 output capacity has decreased, which directly reflects the continuous improvement of the power consumption of the graphics card and the "distinct" contrast between the continuous decline in the CPU power consumption.

The standard power supply has not yet been listed in batches, and only a few "grabbing the beach", so it is recommended that users who want to buy "hold currency to be purchased" for a period of time. Since the ATX2.3 standard is optimized compared to the ATX2.2 standard on the dual -road 12V output, it is "tailor -made" for the next stage CPU, graphics card and other accessories, which can better "appetite" of these mid -to -high -end new products. Therefore, the author recommends that in order to match a set of entertainment hosts with good upgrade potential, buying ATX2.3 standard power supply will maximize the life of the platform.

, because the ATX2.3 standard has re -planned the single 12V output power specifications, such products must have better competitiveness in terms of price. ", Is undoubtedly a wise choice for entry -level users in the next stage.

This summary of the shopping guide: The three "generation" ATX12V power standards of Intel, each generation is "appropriately cut into the market" before a certain hardware type, which shows Intel's ability to grasp the market trends! With the strong stimulus brought to the hardware market on the listing of Vista, coupled with the rapid popularization of dual -core processors 4xx and 5xx yuan, Intel has already shown the "ATX12V 2.3 standard" sword, and go all out to "face the battle" new PC platform pair pair. The "severe" test of power products.

wholesale cz sterling jewelry 2.2 Version is called a dual -core power supply, that is, the power supply 12V output circuit is upgraded to two sets of independent output from the original group, and does not interfere with each other. The 12V1 specializer is responsible for the power supply of the CPU part and the 12V2 specifically responsible for the power supply of the PCI-E and the external memory motor. And each road has its own overcurrent, overvoltage, short -circuit and other protection circuits. Ultra -power equipment can not affect each other at work. It is more favorable to improve and the stable work of the equipment
