zamak jewelry components wholesale BTX is the abbreviation of Balanced Extended. It is a new specification of desktop computing platform defined and guided by Intel. The BTX architecture can support the new shape of the next -generation computer system design, enabling the industry to manage heat dissipation. The system size and shape, as well as the best balance in terms of noise. BTX architecture characteristics: support LOW-ProFile, that is, narrow board design, the system structure will be more compact; for the movement of heat dissipation and airflow, the line layout of the motherboard will be optimized; Optimized design. Basically, the BTX architecture is divided into three types, which are standard BTX.Micro BTX and Pico BTX. From the perspective of size, the entire series of BTX platform motherboards are not smaller than the ATX motherboard, so the development of BTX is not a smaller desktop computer, but the more flexible circuit wiring and modular component areas are the BTX’s of the BTX. The key point is. Compared with the ATX chassis, the most obvious difference between the BTX chassis is to change the side panel that was only opened on the left to the right. Other I/O interfaces have also changed to the opposite position accordingly. The interior of the BTX chassis is very different from ATX. The most noticeable design of the BTX chassis is the improvement of heat dissipation. The position of the CPU. Graphic card and memory is completely different than the ATX architecture. It was moved to the front panel of the chassis instead of the original rear position. This is to improve the heat dissipation efficiency of various equipment in the chassis in order to use heat dissipation equipment more effectively. To this end, the equipment of the BTX architecture will be configured linearly and designing the impedance factors to reduce the heat dissipation airflow; The back of the chassis flows out. This design is not only conducive to improving the internal heat dissipation efficiency, but also can reduce the fan speed of the heat dissipation equipment and ensure the low noise environment inside the chassis. In addition to the location transformation, the BTX specification has also been regulated in the installation of the motherboard. The most important of which is BTX supporting the protection module A buffer usually uses high -intensity low -carbon steels to make it can resist strong external forces and not easy to bend, so it can effectively prevent deformation of the motherboard. In addition, the chassis still has a high hail semi -high. 3/4 high. Full height and stand. Division of horizontal chassis. 3/4 high and high chassis have three or more 5.25 -inch drivers installation slots and two 3.5 -inch soft drive slots. The ultra -thin chassis is mainly some AT chassis, with only one 3.5 -inch soft drive slot and two 5.25 -inch drive grooves. Half-high chassis are mainly Micro ATX and Micro BTX chassis, which have 2-3 5.25-inch drive grooves. When choosing, it is best to use the standard vertical ATX and BTX chassis, because it has large space, many installation slots, good scalability, and good ventilation conditions. It can fully meet the needs of most users. The working principle and nature of the power supply in the TX standard are exactly the same as the ATX, and the specific indicators are similar, and they can also achieve a soft power -on. Sleep and wake up. Remote control opening and shutdown functions, the trend of high -power CPU has also added a P4 four -pin dedicated plug in ATX12V, but the BTX standard has added new regulations to the connector of the power supply and the motherboard. The needle connector, compared with the current ATX power supply 20 -needle connector, adds 4 needles ( 3.3V. 5V. 12V and ground line) to increase the ability of the plug to drive the load to reduce the large current through the connector through the connector through the connector The voltage loss caused by the contact resistance is timely, so the current ATX power supply also needs to be used for plug conversion to use on the BTX motherboard. However The connector of the needle. The BTX power supply generally takes into account the ATX motherboard.
wholesale brighton jewelry On IDF2003, Intel launched a new generation of chassis and motherboard structure specifications -BTX specifications. It is the successor of ATX and will be popular in the future. 1. Introduction to BTX 1. The main board of the motherboard structure is often called the platform of the computer. It is the key part of the computer. It connects the chipset, various I/O control chips, extended slots, power sockets and other components. According to the layout and arrangement methods, size, shape, and power specifications used by the components on the motherboard, the industry has formulated the corresponding industrial standards for the motherboard and its power supply, chassis, etc., that is, "structural specifications". For example, the ATX architecture motherboard we currently use, ATX is a structural specification. There have been many types of structural specifications such as AT, Baby ATX, Micro ATX, LPX, NLX, Flex ATX, among which the structure of AT and ATX is the most famous. The AT architecture is the most primitive board. It is generally used in the early 586 models and has long been eliminated. The ATX architecture replaced is the current mainstream specification standard.
The picture shows: The ATX motherboard architecture 2. What is the BTX specification, but with the further development of the personal computer, the ATX specification gradually shows some shortcomings. Especially with the emergence of new technologies and new bus such as Serial ATA and PCI Express, the performance of the ATX architecture in terms of heat dissipation performance, anti -signal interference, noise control and other aspects are already difficult to satisfy, so "BTX" was born, and it was born. The full name is "Balance Extended". 2. BTX Three Brothers
The picture shows: In order to meet the needs of different users, the BTX Tongmen Three Brothers are divided into three styles -standard BTX, Micro BTX, and Pico BTX, respectively support three different sizes.
The motherboards of the three BTX architectures are the same in terms of layout. different. This design makes BTX more flexible. Third, the new specifications and new features are compared to ATX, the BTX specification mainly has better performance in terms of heat dissipation, noise control, etc. So how do these advantages be realized? 1. In excellent heat dissipation performance (1) Improved motherboard Yuanyuan In order to enhance the overall heat dissipation effect of the device layout
, the BTX redesigned and deployed the position of each component on the motherboard and the position of the expansion interface on the motherboard. The BTX architecture arranges the main components of the system on the upper part of the motherboard, so it reduces the size of the motherboard. It only needs to remove the excess peripheral equipment extension slot to achieve. In the BTX architecture, the CPU is the core of the entire heat source. The position of the CPU socket was moved to the front side of the motherboard, next to the air inlets on the chassis. The location of the North -South Bridge chip has also been adjusted. The distance between the North Bridge and the South Bridge has been shortened, and it is basically on the same axis as the CPU socket. In this way, the wind blowing from the CPU heat dissipation module can directly blow directly to the north -south bridge chip to take away the heat on the chipset. It is not difficult to find out that the location of the graphics card is basically on the same axis as the CPU socket. Although the graphics card has a separate heat dissipation system, the airflow blowing from the CPU can also assist the graphics card heat dissipation. When the cold air via the CPU, the North -South Bridge chip, the graphics card and other board cards, when it is on the side I/O interface, the hot airflow will soon be pulled out of the chassis by the power fan. Through the role of the CPU fan and power fan, the entire system forms a very smooth heat dissipation channel. The airflow in the entire system is very regular, so the heat dissipation performance is better than the ATX architecture. (2) The excellent modular design and layout In order to enhance the heat dissipation effect, the components are modularized in the BTX specification, and the layout is more scientific. For example, the CPU and its radiator constitute the first module. The South Bridge North Bridge and I/O interfaces are a module. The extension card is an independent module. The power supply part is a module. Group. If this design is mainly to ensure the effect of air circulation in the system. (3) Enhanced heat dissipation module
The enhanced heat dissipation module In the BTX architecture, the CPU cooling module adopts a high heat dissipation module. Although it is mainly composed of heat sinks and fans, in order to improve the heat dissipation effect, the diversion has been adopted. Tanks, sealing circles, etc. The diversion slot is wrapped around the CPU heat sink to ensure that the airflow flows between the heat dissipation fins. After the airflow flows through the CPU, some will reach the graphics card or the PCI Express slot to heat the graphics card. On other components of the system. 2. In the more scientific installation and fixed method BTX specifications, a new screw hole layout method appears, which makes the motherboard uniform and easy to install. In addition, the BTX motherboard with optional SRM accessories will be more firm and stable. 3. A large number of new bus and interfaces adopt a large number of new bus and interfaces in the BTX specifications, and some old bus and interfaces will disappear, such as serial ports and ports. In the future, the new BTX specification may even abandon the PS/2 interface. In order to replace the traditional I/O interface, the BTX specification increases the number of USB interfaces on the panel. Of course, the position of the space will be used for new equipment or interfaces such as Ethernet and Bluetooth. In the BTX specification, the PCI Express bus will become a dazzling star. Among the 7 extensions of the standard BTX motherboard, there is a PCI Express X16 slot, two PCI Express X1 slots, and 4 32 -bit PCI slots. In the BTX standard, the graphics card will be mainly based on the PCI Express X16 interface. 4. Rich and diverse power supply modes In terms of power supply, BTX did not deviate from ATX. From the sample and heat dissipation part released by Intel, the power supply has changed a lot. However, in fact, it is very likely that the appearance of the power supply and the location of the heat dissipation fan. The actual power specifications have not changed much. Compared with the old specification ATX, BTX is quite obvious. In addition to being applied to desktop computers, it will also be applied to server and workstation. If you want to make full use of PCI Express and Serial ATA and no longer need traditional interfaces, then you are likely to become the first batch of BTX motherboards. However, whether BTX can become a personal computer standard is still unknown. Although the future will be bumpy, I believe that BTX will eventually replace ATX with many advantages.
icon collection jewelry wholesale ATX is the working power supply of a computer. The function is to convert the power supply of AC 220V into the DC 5V, 12V, and 24V power supply used by the computer ....
BTX power supply is the PC design of the BTX standard design. Power, but BTX power supply is compatible with ATX technology. The working principle is basically the same as the internal structure. The output standard is the same as the current ATX12V 2.0 specification. The ATX 12V, CFX 12V, and LFX 12V power specifications are derived on the basis of the original ATX specifications. This is also the difference between it and the ATX power supply.
