An 8-pin connector is a specific connection on the graphics card to connect with the power supply and deliver up to 150W power. Connecting an 8-pin graphics card to your computer can seem challenging at first, but it doesn’t have to be. With the right setup and knowledge, you can get your graphics card up and running in no time. In this article, we’ll provide a step-by-step guide on how to connect 8 pin graphics card to your computer. We’ll also discuss what type of cables you need, how to install drivers, and more. Let’s learn!

Key Takeaways

  • Start by checking the 8-pin connections on the graphics card and power supply unit before starting the process.
  • Insert the 8-pin cable at the appropriate spot on the graphics card and power supply unit and firmly secure the connection.
  • Secure everything, like the graphics card with screws if it’s disassembled and the 8-pin cable via the thumbscrews.

Quick tips for connecting an 8-pin connector

Although there are many factors to consider when connecting your graphics card to the power supply using the 8-pin power connector that also has been discussed, here are a few quick tips that you must consider throughout the process. Those include as follow: 

  1. Double-check that your power supply has an 8-pin connector before connecting your graphics card.
  2. Ensure the cable is inserted firmly into the connector and secured with the thumbscrew.
  3. Use the correct cable - make sure you’re using the correct cable for your graphics card. Some graphics cards require a 6-pin or 8-pin connector, while others require two 6-pin connectors.
  4. Do not attempt to connect the 8-pin cable to any other components in your system. It is incompatible with any other device and could cause damage if misconnected.
  5. Always keep your system powered off when connecting the 8-pin graphics card.
  6. If possible, secure the cable to the back of the graphics card so it does not become loose during use. This will ensure a secure connection between the graphics card and your power supply.
  7. Always wear safety equipment, such as anti-static gloves, when handling sensitive computer components.
  8. Check for any visual signs of damage on the graphics card before connecting it to your system. If any issues are found, contact the manufacturer for further instructions.

How to connect 8 pin graphics card?

Learn how to connect a graphics card with 8-pin connectors. The method is described below:

Step 1: Check if your PSU has an 8-pin connector

It is essential to check if your power supply unit (PSU) has an 8-pin connector before connecting an 8-pin graphics card. Most modern PSUs are equipped with 8-pin connectors, but it is still worth verifying that you have one.

  • The 8-pin connector looks like a large rectangular block with 8 pins in two rows. It should be easy to identify, as it is usually labeled “PCIe” or “8 pin” on the PSU. Some power supplies may have two 8-pin connectors, so make sure to use the correct one.
  • If your PSU does not have an 8-pin connector, you will need to purchase an adapter or upgrade your PSU before connecting your graphics card.

Step 2: Insert the 8-pin cable into the connector

Once you’ve confirmed that your power supply has an 8-pin connector, it’s time to plug in the cable. 

  • First, locate the connector on your power supply. It should have an 8-pin port with a round plastic lip on end.
  • Take the 8-pin cable and insert it firmly into the 8-pin port. Be sure to push the cable in and ensure it is secure. Once you have done that, you can move on to the next step of the process.
  • When inserting the 8-pin cable into the connector, make sure to align the two notches located at the end of the cable with the pins inside the port. If the cable isn’t correctly aligned, it won’t fit into the port. So make sure to double-check that it is properly inserted.
  • Once you have inserted the cable, give it a gentle tug to ensure it’s secure. You should also hear a click once the cable has been securely inserted. That’s it! You’ve now successfully inserted the 8-pin cable into the connector.

Step 3: Secure the cable with the thumbscrew

Once the 8-pin cable is inserted into the connector, the next step is to secure the cable with the thumbscrew. 

  • Locate the thumbscrew at the end of the 8-pin connector. You may need to use a flathead screwdriver to tighten the thumbscrew. Ensure you don’t over-tighten it, as this can damage the cable or connector. If the thumbscrew is too tight, you may need pliers or screwdrivers to loosen it up. 
  • Once the cable is secure, you are ready to connect the other end of the cable to your graphics card.

Step 4: Connect the other end of the cable to the graphics card

Once you have the 8-pin cable inserted into the power supply and secured with the thumbscrew, you will need to connect the other end of the cable to the graphics card.

  • You may have an 8-pin or 6-pin connector, depending on your graphics card model. To properly connect the 8-pin cable to the graphics card, ensure that the pins on the cable match up with the pin holes in the connector.
  • If your graphics card has a 6-pin connector, you must use two separate cables from the power supply. One cable should be a 6-pin, and the other should be an 8-pin. As before, ensure the pins on each cable line up with the pin holes in their respective connectors.
  • Once everything is plugged in, you must press down on the connector until it clicks into place. This ensures that the cable is securely connected to the power supply and graphics card.

Step 5: That’s it! Secure everything 

Once you have inserted the 8-pin cable into the PSU connector and secured it with the thumbscrew, it’s time to connect the other end of the cable to your graphics card. You should find a similar 8-pin connector on your graphics card, which you can insert the cable into. Once that’s done, you’re all set! Ensure that both connections are secure and that you haven’t left any screws or parts out of place. After that, you can enjoy using your new graphics card and all its features!


Connecting an 8-pin graphics card to your computer is a relatively simple task as long as you have the necessary components and know where to plug them in. When connecting, start by checking whether the PSU has the appropriate connectors for 8-pin connections. Once done, insert the 8-pin cable, secure the cable with adequate thumbscrews, and connect the cable to the graphics card. Once done, don’t forget to secure the graphics card as you have done for the power cable. You can read the in-detail steps for better understanding.
