A PSU (Power Supply Unit) provides all the power required by internal components of a computer such as a motherboard, hard drive, etc. It is installed inside a computer case and has various types of sockets matching the type of internal components.
A GPU (Graphics Processing Unit) is an electronic circuit board that manages your 3D graphics in games or files on your PC. GPUs are capable of controlling displays in any known OS including Windows, Linux, or Mac systems. In this article, we will discuss how to connect a 6 pin PSU to 8 pin GPU.
How To Connect 6 Pin PSU To 8 PIN GPU?
For connecting a GPU to PSU, there are generally three connectors used. One is 24 pin (male), another one is 8 pin (male) and the last one is 6 pin (male). Generally, you find these types of power connections in motherboards. All you need to do is just match the colors.
If you want to connect 8 Pin GPU with 6 Pin PSU, then follow the below steps:
Step 1: Open your computer case and extract out both the power supply unit and graphics card from it by removing all the screws holding them.
Step 2: Now remove all the cables required for both the components like PCIe cable/floppy drive connector/SATA connectors etc using their respective levers on each component.
Step 3: Once you have removed all the cables, set your graphics card aside.
Step 4: Now take out an 8 Pin PCIe cable from a PSU and a 6 Pin PCIe cable from a graphics card. You will also require two screws for this connection to make it firm and stable.
While connecting it after measuring both the power connections, match the colors of pins on both the connectors if they are not the same then just turn them in such a way that colors match with each other at their ends.
Now connect one end of the 8 Pin PCIe cable to your GPU securely and connect another end of the 8 Pin connector to PSU by screwing its head so that it doesn’t get loose over time.
6 Pin Vs 8 Pin Connector – Which one to use?
Both these types of power connections are available in the market. So, you will have to decide which one you need. Generally, if your graphics card has 8 Pin connection then it’s better to go for an 8 pin PSU as well so that both are compatible with each other and work properly. On the other hand, if your graphics card has a 6 pin connector then it is better to go for a 6pin PSU as well instead of buying an 8Pin PSU since they are compatible with each other.
When connecting a 6 Pin GPU with an 8 Pin PSU just remember to match the colors of pins at their ends or else they will not get connected easily. You can connect them even by rotating the power connections so that colors match.
Connecting the 8 pin GPU with 6 pins PSU won’t damage either of the components however it will not work properly as both are incompatible with each other. So, before buying a new power supply unit for your graphics card just make sure that the power connections are the same to ensure proper functioning.
Can 6 Pin GPU Connect To 8 Pin?
Yes, a 6 pin connector is compatible with an 8 pin connector. A 6 pin PCIe power cable can be connected to an 8-pin GPU slot on most systems. However, there are some cases in which this connection may not work.
In the case of a graphics card that has a six-pin PCIe power port and a system with an eight-pin PCIe power port, the six-pin connection will not provide enough wattage for the GPU to function properly.
In such instances, the use of both ports is required. This means that users need to plug two separate cables from their PSU into the graphics card: one from the eight-pin and another from the six-pin port on the PSU.
If your system does not have an 8 pin PCIe port, the card may still work since it will draw power from other available connections such as SATA and Molex ports on the motherboard.
Will A 4 Pin CPU Connector Work In An 8 Pin Socket?
Yes, a 4 pin CPU connector can be connected to an 8 pin socket. In fact, this is not the only case in which you will encounter mixed ports. There are other instances where you will need to connect either a 4 or 6 pin GPU power cable to a PSU with an 8pin port.
Use of both ports is required for some systems. This means that users need to plug two separate cables from their PSU into the graphics card: one from the 8pin and another from either 6 or 4 pin port on the PSU.
Will Connecting Two Graphics Cards Damage My Motherboard?
Connecting two graphics cards to your motherboard can damage it if you do not connect them properly. If done so, there are chances that they might draw power in excess of what your motherboard’s PCIe slots are capable of delivering. When this happens, they will burn out and leave you with a useless chunk of metal and plastic.
When connecting more than one GPU, ensure that you consult the user manual of your motherboard before doing so since different motherboards from different manufacturers have variations in pin configuration.
In addition to this, do not forget to consult your graphics cards’ user manuals as well. They provide a list of motherboards that are compatible with the GPU so you can avoid unnecessary risks.
What Is The 4 PIN Connector On A Motherboard For?
The 4 pin connector on a motherboard is used to power the CPU. The four pins are usually labeled as ‘CPU Fan’ so you will know which one provides power for powering up your CPU fan.
When installing a stock cooler onto your CPU, connect this cable to the appropriate connection on the cooler so that it can function automatically without requiring any user intervention. If no cooler or an aftermarket cooler is installed then this cable may not be required by the system.
What Is The 6 Pin Connector On A Motherboard For?
The six-pin connector on a motherboard, in most cases, is used to power the PCIe x16 slots. Some motherboards have four of these connectors while others may have eight or more. The number of connectors depends upon the number of physical x16 sized slots that are present on the motherboard.
When installing a GPU, you need to ensure that the appropriate connections are plugged into their respective ports so that they can provide adequate power to run your graphics card without damaging it. When using an SLI or Crossfire setup with multiple GPUs, this is even more important since both cards will draw power from this one cable.
What Is The 8 Pin Connector On A Motherboard For?
The 8 pin connector on a motherboard is used to provide extra power for overclocking purposes. Most modern motherboards have an 8pin socket where you will need to plug in your PSU’s GPU cable if it does not match up with the available ports on your motherboard.
The 8-pin power connection is used to deliver extra wattage to the graphics card and provide additional stability when overclocking. This increases the overall efficiency and performance of your GPU during high demanding tasks such as gaming and video editing.
PC Won’t Boot Using 8 Pin CPU Power Connector
A PC that will not boot when connected to an 8 pin CPU power connector is probably experiencing issues with the PSU.
If the PC supplies power and it is connected correctly, but there are no signs of life such as fans running or lights turning on, then the issue could possibly be with your PSU’s ability to supply enough wattage for your system components. It may also be possible that the motherboard requires more than 300 watts in order to function properly.
In cases where a computer has two graphics cards installed and only one has a power connection while the other does not (or if they both have power connections and only one works), you can be certain that the problem lies in either your PSU or motherboard. Check whether both GPUs receive power when connected to a different power supply to confirm this.
In cases where neither GPU receives power, you will need to contact your PSU’s manufacturer for assistance. If one of them works while connected to another power supply, then the issue is most likely with the motherboard and not the PSU.
If your PC refuses to boot even when connected via a different PSU cable, then it may be possible that your CPU fan isn’t connected properly or at all which will prevent your motherboard from receiving CPU power. In such cases, ensure that both CPU fans are plugged in correctly or replace them if it fails to function as expected.
FAQs: How to Connect a 6 Pin PSU to 8 Pin GPU (STEPS)
Q1: My PC does not have an 8 pin power connection, but there are two 6 pin PCI-E connectors. Which one should I connect my graphics card too?
A1: It doesn’t really make any difference which 6 pin plug you use since they both provide the same amount of power (75 watts) through these ports. However, it’s recommended that you only connect one plug at a time in order to prevent overloading either port.
Q2: My PSU has an 8 pin connector for providing extra wattage, but my motherboard does not have enough available ports. How do I solve this?
A2: If your PSU is capable of delivering sufficient wattage to run all of your system components then one option would be to get a Y-splitter to split the female 8 pin connector into two male 6 pin connectors. This would give you enough ports for both your GPU and motherboard.
Another option is to buy a new PSU which has more available ports than the one that you currently have. It’s also worth noting that an overkill power supply will not necessarily provide better overall performance compared to a model with lower overall wattage.
Q3: I cannot get my computer to boot and it does not work when connected using a different PSU either. What can be causing this?
A3: If neither of your GPUs receives power then the issue could be with the motherboard or even worse, both GPU fans may not be working as intended or at all due to unrelated hardware issues. In such cases, the best option would be to contact the motherboard’s manufacturer for assistance and if no signs of life are detected, then you will need to replace your PSU.
As you can see, the process of connecting a PSU with 8 pins is not very difficult if you know what to look out for. In cases where your motherboard only has 6 power connections, then this article should have been enough to help you understand how to solve this issue by using one or two Y-splitters.
In cases where neither GPU receives power when connected with a different PSU, then it’s pretty clear that there is an underlying hardware problem that will require further investigation and perhaps even replacement of either your CPU fan or motherboard.
