What Is My Power Supply

What Power Supply Do I Have?

A PC user needs to know about their Power Supply Unit(PSU). Apart from that, the user should have a basic knowledge about every component of their PC, which will help them upgrade or fix specific elements of their PC. If the user wishes to upgrade the graphic card, processor, etc., of their PC, they must know if those components are compatible with the present PSU. Otherwise, the user might have to change the PSU itself. Following are some necessary specifications and functions of a PSU:

  • Manages temperature of a PC
  • Manages the fan speed
  • Maintain constant power rating throughout the system
  • Have connections all over the motherboard
  • Provide additional power to the graphic card

How to check what Power Supply Unit I Have?

There are two methods to check the Power Supply of the PC. The first one is to directly open the CPU and look for the Power Supply Unit(PSU). If the user has difficulty recognizing the PSU or locating the version and type of the model, they can look for the PC’s technical specification.

If the person can dismantle the CPU, then follow the following steps:

  • Disconnect the CPU from any external power supply. Make sure the PC does not have any power supply before you touch the internal components.
  • Open the hood of the CPU.
  • Look for the PSU ( which is a big box attached with the fan of the processor).
  • The label will provide the user with the details of the PSU.
  • If the PSU is under a cover/casing, it might require the user to open the container to access the necessary information.

The other method of accessing the PSU specification is relatively easy, which does not require the person to open any hardware component. You can follow the following steps to do so:

  • Look for the CPU manufacturer. You can find a label for it on the CPU itself.
  • Go to the manufacturer’s site, and you have to search for the model of their CPU under the section of products(i.e., PC)
  • If you have the CPU packaging, they can find the PSU details on the box itself.

For the PC whose every product is integrated by the same provider, the user can find its details on the provider’s website or the box, as described in the above steps.

How do I check my PC wattage?

Watt or Wattage is the unit of Power Supply. It is also known as power supply unit wattage. To check that, follow the following steps:

  • Open the CPU and look for PSU.
  • Look for the label on PSU. There you might find the Wattage of the PSU in bold and huge fonts written in the units of Watts(W), or it might be present in the category of Max-Power.

For an integrated PC, the user can follow the following steps:

  • Go to the manufacturer’s website, and search for the respective model of your PC.
  • You might find the PSU wattage under the category of Power supply.
  • The PSU wattage will be in the unit of Watt(W). PSU varies from a range of 200W to 1800W at most.

How can I check my power supply without opening the case?

To check the specification and detail of a PC’s power supply, the user can search the respective product on the manufacturer’s website and look under the category of Power Supply. 

If you have access to the Packaging of the PC(i. e., The box in which the PC arrived), you can check the power supply’s details on the label present on the box.

If the user can access none of the above methods, they can contact the manufacturer via phone/email/social media and ask for the necessary details. The user can also contact the customer service center in their local market for the details of PSU.
