The power supply can be a big metal box that supplies electrical energy to one or more electric loads. In computer, this will gives power to the motherboard and several peripherals to create it function. There are specific kinds of power supply like regulated power supply, the one that controls the output voltage or current to a distinct value. The controlled value is held nearly constant in spite of variations in either load current or the voltage supplied by the power supply's power source.
Power Supply is extremely essential for a specific device consequently studying Power Supply Repair is so much useful. Although most issues of it's just simple, becoming knowledgeable of the best way to fixed it can save your dollars than to go to technician.

Here, I am going to show some procedural steps on how you can troubleshoot a defected power supply. We shall assume that this can be a power supply of PC. The very first things you have to do is look under your desk and see if the PC is plugged into the wall. Try to establish if the power comes on or not. You might be asking the way to do that, well, it is possible to hear fans turning and drives motors spinning up, see small lights on the front of the CPU case or hear any beeps.
If the system case is hot (if you get a shock) pull the plug quickly - you've a ground failure and a short. If your hearing is not good, you'll be able to constantly check to see if the power supply fan is making a breeze. Monitors are powered independently, so unless you're looking at a notebook PC, a live screen doesn't indicate a working power supply.
If there’s no power, and you’re plugged into a power strip or surge protector, the strip is probably the culprit. To test it, simply eliminate the PC’s plug from the strip and plug it into a wall socket. If the PC begins working, the problem is within the strip. Usually, the problem can be a blown fuse or perhaps a tripped circuit breaker. You’ll discover each in the cord end of the strip. The last item you must test prior to popping the hood could be the power cord itself; replacing it with an additional cord is the fastest and safest approach.
Many power supplies have a built-in power switch which isn’t accessible until you dis mantle the unit. In the event you have a tower computer case, although, the switch is located on the front panel, and connected to the power supply through 4 wires. All you have to do is unplug the wires from the switch - using the computer unplugged from the wall, naturally -- and test the switch with an ohmmeter. See DIY Switching Power Supply Repair for more related topics.
If you wish to do a hot test of the switch (that is, bypass the switch), you are able to short the power wires together utilizing two insulated jumper wires and plug the personal computer back into the wall. Just be cautious that the jumpers don’t touch anything.
You need to remember always that it is necessary to make sure you understood the Power Supply Repair safety first and things will turn into simpler. Understanding the safety process above can protect your life.
