The computer power supply is a device that converts 220V AC into DC power and supplies power for computer accessories such as CPU , motherboard, hard disk, memory stick , video card, optical disc drive, etc. It is the hub for power supply of various parts of the computer and is an important part of the computer. So what kind of computer power is good? How to check the computer power? The following decoration home decoration network Xiaobian will answer for you one by one, hoping to help everyone.
What kind of computer power is good?
. 1, AT power: the power of the AT form factor popular ATX power similar, but the main power connector and ATX power different. The AT power supply has two motherboard power connectors ( P8 and P9 ), each with six pins that connect the power system to the motherboard. It is worth mentioning that the design of P8 and P9 was not fully standardized. It was only because IBM originally used this design that it was promoted.
2 , ATX power supply: ATX power supply is currently the most popular power supply specification, first introduced by Intel Corporation in 1995 , the current latest version of the specification is ATX12V 2.31 version. The ATX power supply made a major improvement to the main power connector at the time. It mainly added two output voltages of 3.3V and 5VSB and one PS-ON signal. With 5VSB and PS-ON signals, you can implement software shutdown, keyboard boot, network remote wake-up and other functions.
3 , SFX power supply: SFX power supply is specially designed for small systems including a limited number of hardware. It provides slightly less continuous power and 4 levels of voltage ( 5V , 12V , -12V and 3.3V ). For small systems, this capacity is sufficient. The SFX main power connector is the same as the ATX . After all, the two are compatible, so the player does not need to worry about the incompatibility of the motherboard after selecting the SFX power supply. However, due to the small number of SFX power supplies and high integration, the price is much more expensive than the ATX power supply.
4 , BTX power supply: BTX is a new specification for desktop computing platform defined and guided by Intel , and is compatible with ATX technology. Its working principle is basically the same as internal structure. The output standard is the same as the current ATX12V 2.0 specification, and it is also used like the ATX12V 2.0 specification. 24pin connector. However , the internal structure of the BTX platform is very different from ATX . In the past, only the side panel that was opened on the left side was changed to the right side. Other I/O interfaces have also been changed to the opposite position.
5, TFX power: TFX power are small, elongated strip, the standard width dimensions of length 175mmx 82mmx 41mm high, the standard ATX power 150mmx high long 140mmx width 86mm. Due to the size limitation, the current maximum power of the TFX power supply is 350W , which is much lower than the ATX power supply. At the same time, pay attention to the power of the dual 12- channel output to avoid insufficient power supply for the small steel gun platform.
6, FLEX power: In March 1999, Intel introduced the Flex-ATX motherboard form factor, as a supplement to the Micro-ATX, and its name comes from the English "Flexbility", meaning flexible, elastic meaning. In addition to the area reduction, other specifications are the same as Micro-ATX ( version 1.0) and standard ATX ( version 2.03) , which means that Flex-ATX can be immediately applied to any ATX or MicroATX . However, due to the low-end and small positioning relationship, the FLEX power supply was quickly replaced.
How to check the computer power?
Method 1 : Click the “Start†button; click “Control Panel†in the start interface ; click “Hardware and Sound†in the control panel page ; enter the hardware and sound interface and click “Power Optionsâ€; then you can see the power related settings.
