It is often necessary to find out the power of the power supply unit only when the time comes for purchasing new components and you need to know for sure whether the currently installed power supply unit will be able to handle the new hardware, or whether the power supply unit will have to be changed too.
Instructions
Step 1
The easiest and most reliable way to find out the capacity of your power supply is to open the side cover of the system unit (computer case) and find the medium-sized "box" from which the most wires go. This will be your PSU. The location of the unit in the computer case may vary depending on the shape and configuration of the case, but basically, the power supply unit is located in the upper left part of the system unit. In the lower part of the case, the blocks are located quite rarely and, basically, these are gaming models of cases.
Step 2
Pay attention to the case of the power supply. Every self-respecting manufacturer must stick a sticker with all the necessary data about the power supply. Often not only the power consumption is indicated there, but also the voltage of certain nodes. Sometimes even stickers are not required and the power is written in beautiful large letters somewhere on the side of the power supply case.
Step 3
If you do not see any identification markings on the body of your power supply, then most likely you should throw out such a block and replace it with another one, because the lack of information on the power supply unit is a sign that it was produced, if not by handicraft methods, then exactly at a little-known plant with low-quality equipment. But the safety of all other computer components directly depends on the power supply. The slightest voltage drop - the "handicraft" unit fails, supplying a destructively high voltage to the motherboard, which can lead to the failure of the processor, video card, memory sticks, etc.
Step 4
Look at the invoice that was given to you when you bought the computer if you need to find out the power of the power supply unit, but you cannot open the case. Or take the system unit to a service center for diagnostics - most likely, they are able to determine the brand of your power supply without opening the case.
Step 5
Do not try to find a program that could show you information about the power of your power supply unit - such programs do not exist and cannot exist for the reason that no sensors are installed in ordinary power supplies, the readings of which could be read by the program. The only exceptions are special "overlocker" models of power supplies intended for further "overclocking". In this case, the program will be attached on a disk in a box with a power supply.
