How to Connect Power Supply Cables? Connect PSU Cable To Motherboard

You can get a 6-pin or 8 -pin power connector according to the power requirements of your GPU. As you have connected a suitable power connector, insert GPU into its slot and combine it with the power connector.

A graphic card is the most crucial element for better-looking power-loaded activities and visuals. A graphic card’s requirement depends on your power usage, whether you want to play LEGO Star Wars or edit videos.

If you purchase a graphics card for your computer, you may require instructions to connect the graphics card to the power source.

You can get a 6-pin or 8 -pin power connector according to the power requirements of your GPU. As you have connected a suitable power connector, insert GPU into its slot and connect it with the power connector.

As you finish reading this post, you will understand how to connect a GPU to a PSU. Moreover, you will also get information on which power connector works best for a graphic card.

How Can I Connect GPU (Motherboard) to Power Supply?

You will get easy step-by-step instructions on connecting the GPU to the power supply. Before that, you should be familiar with the materials and power connectors explained in detail.

It is also important to keep notice of your graphic card power requirements.

The materials you will need for the process:

You will require the following material while connecting the graphic card to the power supply:

  1. Graphic card 
  2. Power supply 
  3. Motherboards having PCI Express x16 slot 
  4. PCIe power connectors on your power supply.

Types of power connectors 

PCIe wires have the function of connecting graphic cards with a power supply. An alternative name for this connector is “graphic card power connector” or “power connector.

There are mainly three types of power connectors:

6- pin power connector 

The PCI Express x16 slot on the motherboard can supply up to 75W of power to your GPU under typical circumstances. A GPU typically uses more energy than 75W.

The most popular power connector, the 6-pin connector, can deliver up to 75W of power for a GPU that requires approximately 150W.

6+2-pin and 8-pin power connector

The two sections of an 8-pin power connector are 2-pin and 6-pin. As a result, it provides the option to use 6 pins when necessary. When paired with the 75W from the PCIe slot, the entire 8-pin power connector produces 225W or 1500W total.

A few powerful graphic cards may require two or three 8-pin connectors, while others may require both 6-pin and 8-pin connectors. The versatile 8-pin connector comes in handy in this situation.

12-pin power connector 

NVIDIA GPU made a 12-pin power connector available for their RTX 3000 series. It occupies the same space as an 8-pin or 4-pin power connector.

This power connection provides 600W of electricity.  This power connector is used sparingly, but NVIDIA and AMD’s energy-seeker graphics cards may change that.

Step by Step Guide to connect GPU to Power Supply Cable:

Here I will provide step by step tutorial to link your GPU to the power supply:

1st Step: Switch off your Computer

Before starting any procedure, switch off your computer’s power supply and let it cool down. Now open the back area of your PC by unlocking any attached screws.

1st Step: Switch off your Computer

2nd Step: Look for GPU Location

2nd Step: Look for GPU Location

Look for a PCI x16 slot if you’re installing a graphics card for the first time. Place the graphic card close to the processor. You must check the location of your old GPU if you plan to replace your graphics card.

3rd Step: Get rid of any Obstruction

3rd Step: Get rid of any Obstruction

Numerous obstacles are present when attempting to plug a GPU, such as errant cables. You must clear the path inside for your work to be simple and done correctly.

4th Step: Connect Power Connector

4th Step: Connect Power Connector

Connecting the power connector to the motherboard is important before inserting the GPU. The PC’s left side contains the location of the power connector.

Depending on the power needs of your GPU, you can purchase a 6-pin or 8-pin power connector. If your GPU requires an 8-pin connector and your power supply does not have one, you can use a 4-pin Molex connector instead.

Molex connectors are frequently used for computer parts such as hard drives, case fans, and optical drives.

5th Step: Insert Graphic Card 

5th Step: Insert Graphic Card 

After connecting the proper power connector, place the GPU in its slot and attach the power connector. Remember to lock with the plastic latches by the slot’s bottom.

6th Step: Final Check 

The power supply and GPU are now connected. Set the PC at its original structure by attaching the back area. Switch on your computer and see if there are any errors.

What happens if you connect an incorrect PSU Cable?

If you connect an incorrect PSU Cable to your power supplies, it can be a very dangerous situation. The cable may need to provide your hard drive with the right power.

If the wrong type of PSU cable connects, it could cause the power supplies to overheat or even spark.

Also, using a faulty PSU cable could damage other components. This could lead to system crashes and even permanent data loss.

So, it would help if you always used the correct PSU cables for your PC.

How to Connect Power Cables to the Motherboard?

When connecting your cables to the motherboard, you must plug in the power, CPU, SATA, and other cables.

The motherboard has various connectors for different types of cables. So it is important to make sure you plug in the correct cable.

Most PC cases have pin connectors that you need to plug into the motherboard. Connecting a power switch cable from the motherboard to the PC case would be best.

Which usually involves plugging a male connector into a receptacle on the PC case. Once all these connects, you can start connecting other cables like USBs and audio jacks.

What PSU do I need?

When choosing a PSU for your PC, there are several factors to consider.

Firstly, you need to determine the power requirements of all components. This includes the CPU, graphics card, and any others.

You’ll need to ensure that the PSU has enough wattage to provide enough power for all your components.

Additionally, you should check that it has enough cables for all your components.

Conclusion:

You can choose a power connector if your GPU requires more power, as I’ve given you a step-by-step guide for connecting your GPU to a power source.

It’s essential to have a thorough knowledge of your graphic card and select a connector according to it because even a tiny error might put you at risk.

Please comment if you find this helpful information. Remember to share this information with anyone who has just purchased a computer or is looking to upgrade their graphics card.

FAQ 

Can I use daisy chained connector on the same GPU?

Yes, daisy connectors are acceptable if your GPU needs no more than 150W of electricity. Otherwise, you should connect the power supply with two separate connections using two wires.

I accidentally used a CPU or another power connector to power the GPU; what to do?

As the GPU power connector has different diameter holes, it is impossible to connect the CPU or other power connectors to the GPU.

Can I use a 6-pin to 8-pin adapter or splitter?

Use an adaptor with fewer pins. An unbalanced power transfer will overload the connector and could seriously harm it.

Do all graphic card requires Additional power?

Most graphic cards can operate on the 75W that the motherboard provides. Although these GPUs have limitations from running intensive PC activities.

Can we hook 2 8-pin connectors up to the 8-pin ports on the card?

Yes, you can connect if it is the requirement of your graphic card.

Do Graphics Cards Come with Cables? 

No, graphic cards do not come with power cables.
