1. Now bitcoin is out of business. The risk is high
2. If you want to use the switching power supply of the computer for other purposes, you can change it as follows:
1. Open the iron box of the power supply, take out the circuit board from the box, and use a brush to remove the st
2. Find the key components. Including: power oscillation integrated block, optocoupler, 12V voltage regulator, pulse width adjusting potentiometer, etc. Find the information of power supply mole
3. First, change the 12V voltage regulator into 15V, and find the pulse width adjustment circuit according to the data of power supply integrated block. Some power supplies do not design power supply fine-tuning, but fixed resistance. Remove the fixed resistance, and connect a potentiometer whose resistance value is basically close to the welding resistance on the two solder joints. Now adjust the resistance of the potentiometer to the maximum
4. Use a multimeter to monitor the 12 V power supply port, turn on the power supply, slowly rece the resistance of the potentiometer, observe the voltage change, and adjust it to 15 v. After stabilization, observe for a little time and connect the false load toaster
5. After it is accurate, measure the resistance of the potentiometer and replace it with a fixed resistance with the same resistance.

3. The general feeling is dangerous. Because the computer power supply is triggered by the main board after it catches the start signal, if you use al power supply in a chassis, I'm afraid it's a bit crowded. If you want two independent power supplies to drive each other, you need to connect the secondary power supply to the 220 V commercial power supply separately, but this should be done by a skilled master. You only need to set the power standard you want, and let him connect it well and mark it well. You see, how many volt power supply is your equipment now? Measure it first and then get the secondary power supply. Warning again and again: the positive and negative poles of the power supply can't be wrong, the voltage can't be wrong, other no problem.
4. For ordinary PC chassis, only one power supply can be installed. Ordinary computer chassis only reserved a power position, and ordinary computer motherboard also only supports a power supply, no extra socket to connect to other power supply
most computers for special purposes, such as small servers, can be installed with multiple power supplies.

5. To combine two power supplies into one power supply, we should first consider:
1, whether the power supply is of the same type,
2, whether the voltage is the same,
3, the internal resistance and impedance of the power supply are all the same, then we can use them in parallel to increase the output power of the power supply. Increase the voltage in series.

6. Yes, you can use the al power controller to connect two power supplies. And then from the controller to the motherboard hard disk and other devices
you can also do it yourself by connecting the commercial power interfaces of the two power supplies, the green line and the black line. However, the sound will be louder. One power supply can be used. There is no need to install two. In the past, I installed three hard disks to connect two power supplies. Now the hard disks have been removed, and the power supply has been removed. It's much quieter.

7.
A computer can use two or more ATX power supplies, as long as you can accommodate them in the chassis. Connect the ATX power supply to the PS_ The on pin wires (green) are connected in parallel, and the power supply is controlled by the host boot switch, and a ground wire (black) of each power supply is connected in parallel
PS_ The position of on pin is shown in the figure below:
8. Does Yingchi gt240 medium version graphics card need external power supply? If you need to use another power supply to power it. However, if the power supply is not enough, it will not be turned off directly. I suggest you see if the capacitance around the CPU of your motherboard has burst, and if so, it needs to be repaired. Shanzhai power is easy to burn capacitor.
9.
The positive and negative series connection of the power supply leads out a line of OV, which is positive 12V at the top and negative 12V at the bottom< br />
10. The two ups are directly connected in parallel, one of which supplies power to the main AC power supply of the two UPS, and the other supplies power to the bypass AC power supply of the two ups
in fact, there are other connection modes. The only thing to note is that the bypass AC power supply of two UPS must be taken from the same power supply.
