You can measure the current and power of a 'power supply', using an ammeter and a wattmeter. With the power supply connected to its load, the ammeter must be connected in series with the power supply's input. The wattmeter's current coil must also be connected in series with the power supply's input, and its voltage coil must be connected in parallel with the supply, taking the instrument's polarity markings into account.

when gate pulse remove when power supply reversed when power supply cut -off
No attempt should be made to repair the power supply. The power supply should be replaced with a power supply of equal or greater wattage.
The internal power supply could be failing, allowing 60 hz power variations to get through.
A Consort EV 265 power supply may be reading low current and power if the capacitors are failing. They will be unable to provide the needed power and operate consistently.
Most likely the power supply or a failing hard drive.

There are many potential causes. It may be due to power-saving settings or features on the computer. It could be a failing monitor or monitor cable, or a loose cable. It could be caused by a failing or loose videocard. If there are other problems, such as the computer losing power during these 'black out', refusing to reboot, or other errors, there could be a hardware problem with the computers internals, such as a failing power supply, CPU, motherboard, or RAM.
Assuming you are referring to the power supply failing in your 20A device, it could cause the 30A breaker protecting the receptacle to trip. It depends on the mode of failure. It is easy to imagine a condition where a short in the power supply could cause a current in excess of 30A to flow to the device and trip the breaker.
The most probable cause of a faded image is a failing bulb but this is not always the case. You might find when you replace the bulb it make little difference, if this happens it is a sign the the power supply in the projector is failing.
When looking for a new computer power supply, don't forget about the basic online markets. eBay and Amazon are well-known, and you can find all sorts of parts for sale. Failing that, many sites have specialties for certain parts, so the Internet should have what you need somewhere.
There may be one or more things failing in your system. The power supply may be failing, your motherboard may be developed bad capacitors, or your memory may be faulty.
