You’ve bought a new computer or laptop recently, but don’t know whether its power supply is compatible with your motherboard.
How do you check?
A power supply unit PSU converts electricity into direct current DC.
This allows computers and other electronic devices to operate.
The PSU also provides power to peripherals such as monitors, printers, and speakers.

There are two types of PSUs: AC adapters and DC power supplies. Both convert alternating current AC to direct current DC, but they differ in their output voltage. An AC adapter outputs 12 volts at 60 Hz, whereas a DC power supply produces 12 volts at 240 V.

Why It’s Important to Know What Power Supply Do I Have?

PSU’s that use “universal” power cords cannot fit different electronic devices without being replaced with additional adapters (plugs). These adapters include items such as external hard drives or RAID systems requiring additional plugs (cords). So unless you’re familiar with which plugs match what devices when shopping for peripherals you may not know if your computer’s plug is compatible with another computer’s power supply before buying additional adapters/plugs if necessary from an electronic store or from Amazon/eBay etc (and this would be expensive).

Moreover many times your computer’s motherboard may not support different power supplies (the reason why most computer manufacturers do not make two models with different specifications) so if your new PSU does not fit with your computer’s motherboard then its compatibility cannot be tested before buying an expensive item that will probably never work properly!


there are three types of connectors found on computers motherboards based on connection type for pc peripheral cards such as pci express etc. They are as follows – agp – accelerated graphics port connector; ps2 keyboard port & ps2 mouse ports with a button usually located somewhere near to these connections on the mother board to which the keyboard and mouse cables are connected through a small plastic rectangular adapter called a “kvm” switch where you can manually switch between the pc input using buttons on the keyboard to bypass the main pc altogether & access a dedicated kvm control box with a small screen monitor where multiple keyboards may be connected as well to control two or more pcs at the same time and one can also insert their graphics card in this small dedicated display to enhance the user interface using a vga cable to either plug into a separate display screen or in a computer monitor connected to your pc and control it through this application called vmu remote which can communicate with one or more remote controlled desktop pcs to login simultaneously from the application itself or another os like windows xp … and windows7.. windows8…. windows 10… also newer operating systems allow one to use a usb type c to usb3 connection with an adapter while older usb ports are usb 2.0 or less which offer faster speeds than earlier ones but still slower than other versions like the updated usb 3.0 offering even faster data transfer rates in todays’ world~ many modern laptops are sold without a mouse included so you need to purchase a wired optical mouse


There is a specification to measure wattage of a appliance and it is called watt. 1 Watt is equivalent to 1 joule of energy per second. If you have more than one appliances, the sum total of all of your appliance must not exceed 100W.
If the sum exceeds this limit, there would be trouble as the heat or energy generated by all appliances at that rate can become excessive.


Voltage is the measure of the electric potential energy stored in an electric field. When an electric current flows through an object, it creates a potential difference between the object and the ground. Voltage is measured in volts and is the strength of the electric field.
For example, a power cord with a 12-volt output has a higher voltage than a power cord with a 6-volt output.

Power Supplies & Its Types

There are many different types of power supplies, each with its own advantages and disadvantages. The most common type of power supply is the ac power supply, which uses alternating current to power electrical devices. Ac power supplies are typically used in homes and businesses.
Another type of power supply is the dc power supply, which uses direct current to power electrical devices. Dc power supplies are typically used in industrial and scientific applications.

How to See Physically What Power Supply I Have?

Power supply is just a term to mean equipment (often a box, cabinet or case) that provides electricity, usually from the wall socket. The power supply plugs into the wall and then provides electricity to devices such as lamps or computers. It does this because it can be very difficult to produce direct current (DC) energy for any length of time at more than small currents.
A computer’s processor consumes DC power; it only accepts AC in which power is first converted from the mains into alternating current (AC) at 220/240 volt frequency by an AC-to-DC converter, and then down converted to 200-300 volt DC which supplies components. This voltage is also often referred as line voltage: most households in Europe have 230 volts at 60 Hz frequency; other regions may have different parameters like 100 volts at 50 Hz or 240 volts on 60 Hz, with various loads connected within each country.
How To Test A Computer For Power?

How Much Beneficial is to know the Types of Power Supply Calculator?

When you buy a new computer, or even a new cordless phone, you need to make sure that you have the right power supply. A power supply is a box that plugs into the wall and provides power to your computer or other electronic devices. Different power supplies are needed for different devices.
For example, a computer needs a power supply that can provide a voltage of at least 5 volts. If you’re using a cordless phone, you might need a power supply that can provide a voltage of 12 volts. To test your computer for power, first identify the voltage your device needs.
Next, find the power supply that meets that voltage. Finally, plug the power supply into the wall and test the device to see if it works.

In conclusion, you probably already know how to find out what power supply you have, but here’s a quick refresher anyway. First, plug your computer into the wall outlet and turn it on. Then, look for the power button on the front of your computer case.
Once you press that button, you’ll hear a series of beeps. This means that your computer has found its power source and is ready to use.
Now, if you want to check the voltage level of your power supply, you’ll need to unplug your computer from the wall socket. Next, hold the power button down for five seconds.
Your computer will shut itself down, and you’ll hear another series of beeps. Now, press the power button again, and you’ll hear two short beeps followed by a longer beep. That means that your power supply is operating at 12 volts.
Finally, if you want to find out which type of power supply you have, you’ll need to remove the cover plate from the bottom of your computer case.
Inside, you’ll find a sticker with three numbers on it. These numbers represent the voltage level 12V, the current rating 1A, and the wattage 100W.
Once you have these pieces of information, you can compare them against the specifications of the power supply that came with your computer. If you’re lucky, you’ll find that your power supply matches the ones that came with your computer, and you won’t have to worry about replacing anything.
However, if you notice that your power supply doesn’t meet the requirements, you’ll need to replace it with a new one.
