The six of the beginner's machine installation diagram power supply install

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 supply and ATX power supply (the Micro ATX is the ATX Branch) two broad categories.

1. At power supply
At power supply power is generally 150w~220w, a total of four output (+5v, -5v, +12v, -12v), the other to the motherboard to provide a P.G. Signal. The power supply output line is: Two 6-pin plugs (respectively labeled P8 and P9) and several 4-pin plugs (with large 4 cores and small 4 cores) for the motherboard, as shown in Figure 1. At the at motherboard and baby at motherboard that are primarily applied at the power supply, the at power supply is now obsolete. The at power supply volume is 150mmx140mmx86mm.

2. ATX Power Supply
The ATX power supply and the at power supply, compared to the volume has not changed, mainly increased +3.3v and +5v StandBy (also known as auxiliary +5v) two output and a ps-on signal, the output line switch to a dual-row 20-core plug to the motherboard power supply. Some ATX power supplies have a switch under the output socket that cuts off the AC power supply and shuts down completely.

Intel l997 February launched the ATX 2.01 standard, followed by the ATX 2.02, ATX 2.03, ATX 12V and other standards, the different specifications of the ATX power supply are backward-compatible. There is not much difference in appearance from the ATX 2.01, ATX 2.02, ATX 2.03 power supply, as shown in Figure 2. But the ATX 12V power supply (the so-called "P4 power") is not the same, it is based on the ATX 2.03 development, many people to the ATX 2.03 power supply and P4 power supplies equivalent, this is wrong. The so-called ATX 12V power supply is the current ATX 2.0X-compliant power supply with an additional dual-row 4-core 12V Plug and a 6-pin plug (labeled P8) that enhances the motherboard's power supply, as shown in Figure 3.
