At, ATX, SFX, TFX, FLEX ... I believe many netizens jumped up and shouted, "What the hell is this?" Ancestral code? No, it's not. Today, the power supply you do not know the second phase of the story, is about these power supply code. What is that? power supply is that rigid square, complex circuit and the ordinary people do not understand the composition of electronic components, but also divided into so many specifications? Yes, because everyone is
1. Briefly describe the classification of the computer chassis.
Chassis according to different classification standards have different classification, first, according to the shape of the chassis can be divided into horizontal and vertical chassis two kinds.
According to the size of the chassis can be divided into ultra-thin, half high, 3/4 high, all 4 types of higher.
According to the chassis structure can be divided into at, ATX, Micro
to measure the power quality of the computer, which includes two aspects: first, to prevent electromagnetic interference in the power grid from the electromagnetic interference generated by the electricity source into the grid, affecting the normal work of the host system; the other is to prevent the electromagnetic interference from the host itself from entering We may have such experience in the daily work, when the computer boot, its nearby electrical appliances such as television, stereo, e
RTX Architecture Full Name reversed Technology Extended, the Chinese definition can be understood as inverted 38 degree design. The RTX chassis is simply the ATX inverted version, except that the motherboard installation direction has been turned 180 degrees and ATX is no different. After turning upside down, the cover changes from left to right and the power is placed at the bottom of the chassis. But the

The immediate network does not require architecture and is subject to time and space constraints.Activity from device broadcast (ASB)The ASB logical transfer can be used to transmit L2CAP user communications to all active devices in a Pico network.Advanced Audio Distribution configuration file (A2DP)The A2DP configuration file describes how stereo quality audio is transferred from the m
Bridge, I/O, power supply mos tube, a variety of slots. If it is found that there is obvious burns, damage, the first to be burned, damaged parts to be replaced.
2, check the motherboard on the PCB whether there are scratches, cut off, PCB burning, drop parts and other man-made failures, such as such a failure, the first to fill the line, fill the work. The main direction of observation is the edge of the motherboard and the back.
Second, before the ATX
, steel plate quality is to measure a chassis excellent and bad important indicators, directly determine the quality of the chassis. Products of poor quality of the inferior chassis because of its poor stability, the use will create problems such as shaking, which will damage the hard drive and other host parts, affecting its service life, and electromagnetic shielding performance is poor, which is harmful to the physical and mental health of users. Tempered Glass side version although beautiful
style, and the glass products are very good impression, this chassis is very consistent with the taste of the author, but this chassis has different from the other chassis special, so select hardware to be around it to unfold.
Chassis size determines motherboard specifications
Now that we have identified this 904 chassis, I will first take a look at this chassis to support which motherboards. By observation, the chassis supports the ATX,M-
location (figure ). The memory used by the motherboard is determined by the chipset, because the beiqiao chip contains an extremely important memory controller. It should be noted that some boards using the via and SIS chipset may support both SDRAM and DDR at the same time, but the SDRAM and DDR memory cannot be mixed. 3. Power Supply and motherboard combination: So far, The ATX Power interface has completely replaced the traditional at Power
RDRAM use the 184pin interface. In fact, it is unrealistic to distinguish between 168pin and 184pin by the number of pins, but we can identify the gaps in the memory slot by identifying the gaps, and it is foolproof. The memory slots with 168pin have two asymmetric gaps between the center and the right. The memory slots with 184pin have only one gap.The RDRAM memory slot of the 184pin has two gaps on the symmetric position (figure ).
The memory used by the motherboard is determined by the chip
the most basic and most important part of the computer. The motherboard is generally a 4-6-layer rectangular circuit board, the above installed the main circuit system composed of computers, there are generally north-south bridge Chip (some north-South Bridge Integration) BIOS chip, I/O control chip, keyboard and Panel control switch interface, LED connectors, expansion slots, motherboard and card DC power supply connectors and other components.
The so-called motherboard structure is based on
three kinds: ATX/M-ATX/ITX, the following is a list.
Board Board Type
ATX: Published by Intel in 1995. As of 2014 is still the most popular DIY a family of specifications, this is what we call the Big board, all kinds of interface complete.
MicroATX (M-ATX): A scaled-down version of the
power will be directly burned off. So the power of the best state of the work in the rated power state, the occasional overload is no problem, but also does not rule out the stability of the problem.
Calculation of rated power of non-standard rated power supply
There are also many power supply manufacturers do not indicate the rated power, although it is also in line with the norms, the feeling is still a consumer suspicion, it is necessary to let everyone use p=u*i calculation to know. You c
The plate type is mainly divided into: ATX (Standard type), M-ATX (compact), Μatx, MINI-ITX (mini), e-atx (Reinforced)
E-atx (Reinforced: Extended ATX, long 305mm* width 330mm, as long as the length remains 305mm, and width of 244mm are called E-
supply is to convert a 220 v ac to a DC power available for the PC. Generally, the power supply converts an AC to 12 V, 5 V, or 3.3 v dc. 12 volt DC is used to drive a device with a motor, such as a hard drive and a CD-ROM drive. 5 V and 3.3 V output are used to supply different components on the system motherboard.
Almost all currently used PC power supplies are at or ATX architecture power supplies. The main difference between the two is the number
the motherboard does not boot the solution:
One, the suspicion of host power supply or bad
First, the power supply, press the switch, if not power, and then unplug the main engine power, with tweezers to the Green Line and black lines short-circuit, look at the power supply fan does not, if the turn, indicating the power is good, failure in the host.
Suspected host switch is good or bad: and then the ATX power cord and the motherboard, the motherbo
