Understanding Different Types Of Gpu Power Connectors

Today I’m here to help you understand the different types of GPU power connectors. As you may already know, GPUs require a significant amount of power to function properly, and that’s where these connectors come into play.

6-Pin Power Connector

Let’s start with the 6-pin power connector. Although it’s no longer actively used on its own, the 6-pin connector was the standard option for many older graphics cards. It delivers 75W of power, and when combined with the PCIe slot, provides a total of 150W. This makes it a suitable option for low-end GPUs.

6+2 Pin Power Connector

Next, we have the 6+2 pin connector, which has gained popularity in recent years. The main advantage of this connector is its versatility – you can use it as a 6-pin or an 8-pin connector depending on your GPU’s requirements. This convenient design allows PSU manufacturers to cater to a wider range of graphics cards without producing separate connectors.

8-Pin Power Connector

Moving on to the 8-pin power connector – this one is becoming more common due to increasing power requirements. It delivers 150W of power straight from the power supply, making it ideal for mid-range GPUs. The good news is that most modern PSUs come equipped with multiple 8-pin connectors, so you don’t have to worry about running out of them anytime soon.

12-Pin Power Connector

The 12-pin connector is another type you may encounter, particularly with the latest RTX 3000 series GPUs. Despite being similar in size to the 8-pin connector, it’s slimmer and capable of delivering up to 504W of power. This makes it a powerful solution for high-end GPUs that demand more power.

16-Pin (12+4-Pin) Power Connector

The new kid on the block is the 16-pin connector, also known as the 12+4-pin connector, which was introduced with the Founders Edition Nvidia 4000 series GPUs. This connector is native to Gen-5/ATX 3.0 PSUs. If your PSU is PCI Gen-4/ATX 2.0, you’ll need an 8-pin to 16-pin 600W 12VHPWR adapter cable to make it compatible.

PCIe x16 Slot Power Supply

While not technically a connector, the PCIe x16 slot is also responsible for providing power to your GPU. It can supply up to 75W of power on its own, which can be sufficient for low-end graphics cards that don’t require additional connectors.

Split Cables and Pigtail PCIe Cables

Lastly, there are split cables or pigtail PCIe cables. These cables can split one connector into two, such as converting a 6-pin connector into an 8-pin or dual 8-pin connector. While this used to be a common practice in the past, it’s not recommended anymore due to potential power supply issues.

Pci-E Converters And Adapter Cables

I’ll start off by saying the first couple in this list are hardly ever used today, but if you find yourself working on an older PC, these handy little cables can help you connect your GPU to your power supply safely and effectively.

4-Pin Molex to 6-Pin PCI-E Adapter Cable

One type of converter you might come across is a 4-pin Molex to 6-pin PCI-E adapter cable. While these are less common nowadays, they can still be useful if you have an older power supply that doesn’t have enough PCIe connectors for your GPU. However, keep in mind that these cables can be less convenient due to cable management issues.

2x 8-Pin to 12-Pin PCI-E Adapter Cable

Another type of adapter cable is the 2x 8-pin to 12-pin PCI-E cable provided by Nvidia for their RTX 3000 series GPUs. These became more common after the launch of those cards due to limited availability of 12-pin connectors. They allow you to use the high end Founders Edition RTX 3000 series GPUs with existing cables, making them a good option if you don’t want to upgrade your entire power supply just yet.

Choosing the Right Converter or Adapter Cable

When it comes to choosing a converter or adapter cable for your GPU, there are a few things to keep in mind: make sure the cable is rated for at least as much wattage as your GPU requires, and try not to daisy-chain too many cables together (as this can lead to power delivery issues). With these tips in mind, you should be able to find the right connector or cable for your setup without any problems.

Using Rtx 3000 & 4000 Gpus With Different Types Of Connectors

Navigating the different GPU power connectors and cable options for current generation GPUs can be confusing, but you’re in luck! I’m here to guide you through which cables to use for your new RTX 3000 or 4000 series GPU, to help make the process as smooth as possible.

First off, let’s talk about the RTX 3000 series. The Founders Edition of the RTX 3080, 3080ti, 3090, and 3090ti come equipped with a 12-pin PCIe adapter cable that is compatible with both 8-pin and 6-pin connectors while the 3070ti, 3070, 3060ti, and 3060 all use the standard 8-pin cable. If your power supply doesn’t have an 8-pin connector, don’t panic!

You can use a 6-pin to 8-pin PCI-E adapter cable instead. Just make sure to pay attention to connector types and their respective wattages to ensure that your GPU doesn’t exceed the maximum supported wattage from your PSU. Most modern PSUs will include 8-pin cables though so this shouldn’t be much of an issue for you.

Now, onto the RTX 4000 series. These GPUs require a 16-pin PCIe Gen-5 connector, which is native to Gen-5/ATX 3.0 PSUs. If you have a PCI Gen-4/ATX 2.0 PSU, you’ll need to use an 8-pin to 16-pin 600W 12VHPWR adapter cable.

To prevent any potential damage caused by over-voltage or improper grounding, it is essential to pay close attention to wattages and connector types. This is particularly important when it comes to the 16-pin cable, where extra care is necessary to ensure that the cable is correctly connected.

There have been instances of melting cables resulting from improper connection, which emphasizes the importance of taking the necessary precautions.

Whether you’re using an RTX 3000 or RTX 4000 GPU with different types of connectors and cables, always exercise caution when working with high-powered electricity. And remember these key takeaways:

• For RTX 3000 series GPUs, Founders Editions of the 3080, 3080ti, 3090, and 3090ti use a 12-pin PCIe adapter cable, while the 3070ti, 3070, 3060ti, and 3060 use a standard 8-pin cable. If needed, a 6-pin to 8-pin PCI-E adapter cable can be utilized.
