How to connect 4 ports of computer power to ant miner

The computer motherboard has two groups of power supply, one is 24 pin socket, the other is near the CPU, which is dedicated to power the CPU. The power supply supplies power to the main board, and the plug is equipped with anti decoupling mechanism. First, the direction of the hook should be consistent with the direction of the hook slot of the CPU power supply socket, and then insert it, and lock the hook

The interface of the four round holes on the computer power supply is the big 4Pin interface

the big 4Pin interface (also called big d power interface) is the power plug of the device with IDE interface, such as IDE hard disk, IDE CD, etc. Some expansion cards (such as graphics card, USB expansion card, etc.) also use this plug for power supply

the small 4Pin interface mainly supplies power for the floppy drive. Since floppy disk and floppy drive have been eliminated, this kind of interface is rare now

the power supply voltage of big 4Pin interface and small 4Pin interface is exactly the same, which can be directly converted by changing the plug

sometimes the auxiliary power supply plug of CPU is also called small 4Pin plug. This kind of plug is square, with two rows and two columns, which is different from the small 4Pin mentioned above

the D-type adapter of computer power supply should be used with caution. The 1 / 2 power adapter of

"D-type adapter" can convert the D-type interface separated from the computer power supply into two D-type ports, which can be used when the D-type port of computer power supply is not enough, so it is used more in the server and other computers with multiple hard disks. But this kind of line used more will cause a variety of problems, in general, try not to use it

many server failures that cannot be started are caused by the hard disk. The insufficient power supply or bad channel of the hard disk is most likely caused by the use of some connecting lines. We know that the use of the transfer line extends the length of the line to a certain extent, but the increase of the length will cause the increase of the resistance, and the increase of the resistance will cause the decrease of the current, which will eventually lead to insufficient power supply and server failure

it is not enough to only use the adapter cable, but also use the power cable that converts the D-port into the SATA port. In this way, you need to connect to the hard disk at least twice. I don't know how many times to connect the hard disk cooling fan and the chassis cooling fan

when all the hard disks are connected by the adapter, there are always several hard disks that can not be identified by self-test after each boot, or one or two hard disks show "invalid" after entering the system, which only indicates that the power supply will be unstable after using the D-type adapter

Instead of P4 interface, this is the SATA power interface

the SATA power interface is the main power supply source of the current SATA hard disk, including HDD mechanical hard disk and SSD solid-state hard disk, which can provide + 12V, + 5V and + 3.3V power supply, with 3 pins for each voltage, a total of 15 pins. The current that each terminal can transmit is 1.5A, so the current that 12V, 5V and 3.3V can transmit is 4.5a, and the power is 54W, 22.5w and 14.85w respectively

since most of the SATA devices can work normally without + 3.3V power supply, if players really need a large number of SATA power interfaces, but the power supply itself is insufficient, they can use the adapter cable to transfer and expand from the D-type 4Pin interface

PCI-E 6pin / 6 + 2pin interface: an important source of power supply for graphics card

the same way as CPU power supply, now the independent graphics card is not only powered from the motherboard slot, in order to meet the high power demand of GPU, At present, most of the mainstream or above graphics cards need external power supply, and this power supply interface is the familiar PCI-E power supply interface, mainly including 6pin and 6 + 2pin

PCI-E 6 + 2pin power supply interface is essentially 8pin power supply interface, which is also the difference between separate type and integral type. There is no difference in performance, just for the consideration of compatibility and versatility. Therefore, there are basically only 6pin and 6 + 2pin power supply interfaces for PCI-E graphics card

PCI-E power supply interface mainly provides + 12V power supply. PCI-E 6pin power supply has two groups of + 12V power supply, while PCI-E 6 + 2pin has three groups of + 12V power supply. Generally speaking, each group can undertake 6A power supply, so the maximum output power of PCI-E 6pin power supply is 192W, while PCI-E 6 + 2pin power supply is 288w
