How to Connect RTX 3080 To Power Supply? [FIXED]

Congratulations on finally getting your hands on an RTX 3080! This bad boy is the latest and greatest graphics card on the market, and it’s sure to give you a serious competitive advantage in your favorite games. But before you can start fragging your enemies, there’s one more thing you need to do: connect it to your power supply. 

How to Connect RTX 3080 with Power Supply?

Don’t worry, connecting your RTX 3080 to your power supply is a pretty simple process. Just follow these steps and you’ll be up and running in no time:

Step 1

First, locate the 8-pin and 6-pin connectors on your RTX 3080. These are the same kind of connectors that are used on most other high-end graphics cards, so if you’ve ever installed one of those before, this will look familiar.

Step 2

Next, find the 8-pin and 6-pin power connectors on your power supply unit (PSU). If you’re not sure which ones these are, consult your PSU’s manual. Once you’ve located them, carefully insert the 8-pin connector into the 8-pin socket on your RTX 3080, making sure that all the pins line up correctly. Then do the same with the 6-pin connector.

Step 3

Once both connectors are firmly plugged in, you’re all set! Fire up your PC and enjoy the increased performance of your new graphics card.

What are the Compatible PSUs with RTX 3080?

Now that you know how to connect your RTX 3080 to your power supply, you might be wondering what kind of PSU you need to run this bad boy. Well, the good news is that just about any high-end PSU should be able to handle the power requirements of the RTX 3080. 

If you’re not sure whether your PSU is up to the task, you can check the manufacturer’s website or the label on the PSU itself to find out its maximum power output. As a general rule of thumb, you’ll want a PSU that can provide at least 750 watts of power if you’re planning on running a single RTX 3080.

Does the RTX 3080 Need all 3 Power?

The RTX 3080 requires both an 8-pin and a 6-pin power connector, but it actually only needs two of the three total power cables that are included with most PSUs. 

So, if you’re wondering whether you can get away with using just a single 8-pin or 6-pin connector, the answer is yes – as long as your PSU is powerful enough.

However, we recommend that you use all three power cables whenever possible. This will help ensure that your RTX 3080 receives all the power it needs to perform at its best. 

How Many PCIe Cables do I Need for an RTX 3080ti?

As the most powerful graphics card on the market, the RTX 3080ti requires at least two 8-pin PCIe cables to function. Some power supplies come with an adapter that will convert two 4-pin peripheral cables into one 8-pin PCIe cable, but we highly recommend using two 8-pin PCIe cables for stability purposes. If your power supply doesn’t have enough PCIe cables, you can always buy adapters or splitters that will allow you to connect multiple 4-pin peripheral cables to one 8-pin PCIe slot.

In terms of actual connection, the process is fairly simple. Just line up the two pins on the graphics card with the two slots on the power supply, and then push down firmly until you hear a click. After that, all you need to do is screw in the PCIe cables to secure everything in place. And that’s it! Your RTX 3080ti should now be properly connected to the power supply.


That’s all there is to it! Connecting your RTX 3080 to your power supply is a quick and easy process that anyone can do. Just follow the steps outlined above and you’ll have it up and running in no time. Thanks for reading and happy gaming!
