Advice 1: How to know what kind of power supply in the computer

Often PC users face the problem of finding the right information about the contents of the system unit – not all of them are installed driver. For instance, the model and the power system block in software is almost impossible. And this is very helpful information because when you add new devices to the configuration of the computer know the power supply is necessary.
How to know what kind of power supply in the computer
You will need
  • - screwdriver.
View the technical documentation of the computer where you have to register the configuration settings specifying the device models. Also, the specification may be separate for each piece of equipment.
If you for some reason can't see the computer's documentation, use the alternative. Armed with a screwdriver or a screwdriver and Unscrew the bolts holding the housing side wall.
Carefully inspect the contents of the system unit, locate the unit power. It is located on the right side on the rear wall of the housing in the form of a large box with radiating plumes.
Carefully consider the unit of power, it must be stickers containing information about the manufacturer, model, basic parameters of the device. Usually these stickers glue so that users could easily read the information, but sometimes it also happens that they are placed on the bottom or top side.
In this case disconnect all leads of the power from devices inside the computer, carefully pull them over the base, while making a preliminary sketch wiring diagrams of circuits of the power supply to the motherboard. Unscrew all fasteners that hold the unit 's power and remove it from the housing.
Also try to find out information using a systematic approach, but it is not always effective. Download and install Aida or any other similar utility purposes.
Open it, the system will collect information about your hardware configuration and give it to you after a certain amount of time. In fact, the driver unit power supply is not installed, so learn its parameters in this way would be almost impossible, but worth a try.
Be careful when disassembling the computer, don't lose the fasteners.
Useful advice
If the warranty on the computer did not work, do not open the system unit by yourself.

Advice 2: How to know how much power the PSU

Power block power supply is often required to know only when the time comes to purchase new parts and we should know – "pull" whether installed at the moment, the unit power of new hardware, or have to change the unit of power too.
How to know how much power the PSU
The easiest and most reliable way to learn the power of your unit supply is to open the side cover of the system unit (computer case) and find a medium size box, from where departs most of the wires. This will be your PSU. The location of the unit in the computer case may vary depending on the shape and configuration of the hull, but basically, BP is in the upper left part of the system unit. In the bottom of the housing units are quite rare and mostly is the gaming model of the buildings.
Note the hull unit power. Every self-respecting manufacturer is required to paste a sticker with all necessary data on the unit power. Often there is indicated not only power consumption, but the voltage of certain nodes. Sometimes you may not even need the stickers and the power of writing in nice large letters somewhere on the side of the unit power supply.
If you do not see on the body of his block of power no identifying markings, then you might want to throw a block and replace it with another, because the lack of information on BP – a sign that it was produced by artisanal methods, if not, then just on a little-known plant with poor equipment. But from block power directly affects the security of all other computer components. The slightest voltage drop "artisanal" unit goes down, feeding destructive high voltage on the motherboard that can lead to failure of the CPU, graphics card, memory modules, etc.
View the invoice that you were given when you purchased your computer, if you need to know power unit the powerand open the casing impossible. Or take the system unit in service center on diagnostics – rather, they are able to determine the brand of your unit supply without opening the case.
Do not try to find a program that could show you information on the power of your BP – such programs do not exist and cannot exist for the reason that in the usual units of power do not install the sensors the readings of which could be considered a program. The only exceptions are special "overlockers" the unit model powerdesigned to further "boost". In this case, the program will be accompanied by a disk in a box with power supply.
