1. 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.

2. It's OK to be a transformer, but you can also use interface conversion
3. Unknown_Error
4. What do you mean by control switch? Is that the point of soft start? If so, you can find the power board and write & quot; PS-ON" Then connect it to ground (COM) with a line, and there will be voltage output If not found or not clear, you can take a clear picture to help you see
5. A desktop power supply is only 200 yuan. Are you tired
even if it can be changed, can you stand the fan noise of the server power supply
you can find a desktop motherboard power plug, pull out the pins of your server power one by one, and plug them in order. The electrical parameters are the same.

6. 575W HP server power supply, 12V to 13.8V method
1. Disconnect the PC power supply, connect a rectifier diode IN4007 to 14.3v (no more than 14.7V) in series at the 12V rectifier voltage output, and connect four rectifier diodes IN4007 to 6.2V at the 5V rectifier output
2. Except for the black, yellow and green cables, the cables of other colors can be removed. The green wire is directly connected to the ground (that is, the black wire solder joint). The green wire is used for starting up the PC power supply
3. After all the changes are completed, start up and measure the voltage. The yellow line has 14.3v-14.7v, which is normal. Get a bulb 12v21w (the edge of the bulb is negative, and the contact point is positive), and try it on. After connecting, the voltage becomes 13.7v and the current is 2.1a, which is normal. The transformation is completed, and a constant voltage + floating charger is completed.

7. It can be modified, but the adjustable range is small.
8. It can't be replaced. The server has professional server power supply. Besides, your 12V DC power supply has not been tested, which may cause damage to the firmware. You can go to the server manufacturer (Zhengrui) to find the relevant technical documents or online consultation, it should be clear soon!
9. 12V output connected to a treasure dozens of dollars dcatx mole on the line
