How to Test a Power Supply
Apr 18, · Physical Method [by Opening the PC Case] The most preferred way to know about your power supply or PSU, which is by opening your computer case side panel and look for a sticker or label on it, which provides the important information about your PSU, that includes PSU Name / Model number, Power/Wattage, Voltage and Current details. Nov 13, · First Method. In both cases, one method of checking the power supply is universal and that is manually opening the chassis side panel. It’s easy to know about the power supply of your PC if you have an assembled computer but still, there are some power supplies which don’t mention their power capacity in big fonts as we see on a lot of premium quality power supplies nowadays which .
Do you really want to know what power supply you have in your PC? What PSU do I have? How to check what power supply I have?
So, you want to know which power supply you have? If yes then keep reading this article to know about it. Unfortunately, only power is sent to the computer by the power supply. It is always recommended to know about the components of computers, especially the PSU as it is one of the most important components of a computer. But usually, its importance is ignored by most of the users. So, here are the ways you can find about your power supply specifications.
Now, one question would arise in your mind: what is the need of knowing about PSU?. So the answer to it is that if you want to add a graphics card or say upgrade your already added graphics card or any other component then it is a must that you should know about your PC power requirements. The reason behind it is, this new component will put additional load on your PSU, and it might happen that your computer how to check the power supply on my pc requirements may surpass your PSU Wattage.
After that eventually, it will pressure out your PSU and resultantly it may happen that it might fail or burn down what are the liabilities in accounting it might also cause damage to other internal components.
And also if you are planning for upgrading your PSU then it is necessary for you to know about your current specifications of PSU.
So that now while upgrading it you can choose a superior and more powerful power supply. As I said earlier, its only job is to deliver power to the components. So there is no way to know about your PSU specification with help of any hardware detection software, and the reason being it does not have any communication interface with the motherboard. Note: If you are well aware of the high-end power supply brand like Corsair then you also know about the monitoring and managing of the fan speed, temperature, and power output through their software.
Corsair Link Hub. Keep alert with the latest tech guides here. Just you have to open your computer case side and look for a label or can say sticker available on it. The attached sticker provides important information related to your PSU. We can also say it as Pre-assembled PCs possess their own model or serial number. This is the way in which you can know which power supply you have even before opening it.
You can try this information and know the specific features used inside. If you are techy or say you have enough technical knowledge and know-how to read label then you might know that but if not then I will tell you what all to look into :.
On each and every PSU label, you may find the below-given information:. Below you can find a Corsair RM power supply of Watts. Input Voltage — It is the AC Voltage at which the operation of power supply happens, and this you have to supply to it. Some have an auto-switching mechanism to detect input voltage and can also switch accordingly so they have a power supply in a wide range of voltages. Nevertheless, others also have a physical switch wherein it allows you to select an appropriate voltage depending on the voltage used or supplied in your country or area.
DC Output — It is the output voltage given by your power supply. The above given are also known as Rails. Here V Rail is not listed as it is no longer used but is present for some legacy support only.
Single 12V Rail in a Power Supply. Dual 12V Rails in a Power Supply. It may result in PSU failure or computer shutdown if you overload it. Maximum Power combined — This one is for the maximum power for a single Rail or for combined Rails.
The power is calculated in the product of Voltage and Current that is termed as Watts. So keeping it in formulae:. You can even check the number and types of connectors along with cables for the particular power supply, just by opening the case itself. For example, you generally find in a power supply that is ATX 12V 2. Also, you can download the PSU manual or specs sheet from there. As said earlier, if you have a pre-assembled PC then you can refer to your manual for its specifications as that will state your installed power supply.
But this information may not always be that precise because some of the manufacturers can change the PSU in their newer variants of the same PC model, so what would be more suggested is to always open your PC case side what was the first walt disney movie to check your PSU what is the ending of the hunger games series and specifications.
Stay tuned with the latest Tech information. If you still have any issue regarding the power supply PSU which you using and want to find out its specifications, then you can leave a comment below.

The computer power supply unit PSU is one of the biggest pieces of hardware that directly affects user performance. An adequate power supply is a must for systems to run seamlessly, and many problems occur if the power supply unit fails to provide sufficient voltage levels. For many problems, checking the power supply can bring out the solutions very easily. To test the computer power supply, we must learn about itself. PSU Power supply unit is the main unit through which electrical power is delivered to the CPU of a computer and then distributed.
It converts AC power from household inlets and then converts them to DC power as needed for computer components to run effectively. The power supply unit consists of some regular electric components like a transformer to increase or reduce voltage level, a rectifier that converts AC into DC voltage, voltage regulators to control the output voltage as needed.
Inside the connector, we can see wires with multiple colors. The black connectors work as a ground unit. The gray connector is essentially a voltage level checker, that determines if the voltage is adequate. There are red, blue, orange connectors for voltage supply.
These supply 5V, 12V, and 3. Take the connector while facing the connecting clip towards your face. The green pin is the 4 th pin from the right side. Testing disk speed , power supply, or other units of a PC is great for clearing out issues and make room for improvements.
There are two basic methods to check if the computer power supply is working correctly. This is an easy way to identify if the power supply turns on or not. To check, we need a paper clip. If the clip is coated with paint, we have to remove paint from the two ends of the clip, and the metal portion will come out. Before doing these operations, we should ground ourselves to prevent any unwanted electrical surges that can damage the components.
At this point, the fan should rotate. If it rotates, we can proceed to the next step. Now we have to check if all the connectors are working properly. For this, we need a multimeter. These are relatively cheap hardware found in most electric stores. Multimeters usually have a black probe and a red probe.
There is a knob to switch between AC and DC connections. With the multimeter, we first check the power outlet. Notice that the outlet has a neutral N , a live L slot at the bottom, and the 3 rd one is ground. Next, we rotate the knob to AC connection V with a wave sign. Now we place the black probe in neutral N and red probe into the live L slot and turn on the power. We should see a reading somewhere between V which varies with the rated voltage of individual countries.
If the reading matches the rated voltage of your zone, then the power outlet is ok. Now we have to check if all the pins are giving the voltage as rated in the chart before. To do this, switch the knob of multimeter to DC connection V with a straight line.
At first, insert the black probe into the black pin which is the furthermost. Then attach the red probe to the next red pin The black probe stays in the same place, and we have to try different pins for the red probes. Skip the other black and grey pins, then insert the red probe in each pin one by one and notice the readings. The readings on the multimeter should be close to the values given in the chart.
Check one side of the connector lane, then swap to the other side while placing the black probe to another black pin, and repeat the process again. By checking the individual pins, we can see how much voltage each one gives. The voltages should be close to the original values. If so, then the power supply unit is completely okay. PSU failure can cause a lot of problems. A majorly damaged power supply would fail to boot the computer at all.
Damaged pins can supply excess voltages to the components that can cause the components to damage or even burn out. The cooling fans associated with the power supply can stop cooling effectively, which can increase CPU temperature to a dangerous level. Minor problems associated with the PSU are, blue screens of death BSoD , frequent computer crashing, storage failure , unable to launch apps, hard drive reading errors, and other common problems. If these problems occur frequently, it is best to check the power supply at first.
We can also use 3 rd party apps like SpeedFan that checks if fans or other hardware are working correctly. Damaged power supply units can cause great deals of further damage to your computer if ignored. So, it is best to check if this is working correctly at the first sign of trouble so that you can identify the problem, minimize the damage, and the cost to fix them.

What is the PSU of a Computer? The green connector is the main ON connection. There is only 1 green pin located at pin How to Test Computer Power Supply Testing disk speed , power supply, or other units of a PC is great for clearing out issues and make room for improvements.
Check if PSU turns on or not with a paper clip Check the individual pins with a testing unit like multimeter Checking if PSU Powers On This is an easy way to identify if the power supply turns on or not.
Firstly, we shut down the computer and disconnect power from the wall socket by removing the plug. Open the CPU back cover to expose the power supply. Unplug the PSU connector from the motherboard. Then disconnect the power supply unit from the CPU by removing the screws. Take the pin or pin connector. Notice that there is 1 green pin, some red, blue and black pins.
The green pin is usually located at pin Take the paper clip, and insert one end into the green pin, and the other end to any black pin.
Make sure the PSU is disconnected from the socket before doing this. Plugin the power socket and turn on the power connection. Leave a Reply Cancel reply Your email address will not be published.
