The pci-e slots are powered by the only 2 (if my memory is correct) 12v wires in the 24 pin connector. So, assume around 200 watts can go into the motherboard through the 24 pin connector, which are then split between fan headers, rgb headers, and possibly 12v to 5v / 3.3v dc-dc converters on the motherboard that may power things like ram, m.2 connectors (m.2 has only 3.3v but because a m.2 SSD may go up to 3A when writing, some motherboards don't use the 3.3v from PSU but use a dc-dc converter to produce clean 3.3v from 12v) Typically, the power connectors demanded by the graphics card always come along with PSUs. However, in many cases, when the GPUs get developed too advanced than the PSUs, the manufacturers offer you power connectors and adapters to make the GPU compatible. A 4-pin to 6-pin connector helps you achieve compatibility with your GPU. Besides, the 4-pin Molex power connectors are the most standard connector type accessible today, and they were for all PATA and hard drives. The pin connectors usually have 4 Molex pins inside the adapter or converter cable. This converter cable connects with a 6-pin GPU to harness the external power supply. 2. 4-Pin Molex To 8-Pin PCI-E Power Adapter Cable In any situation, it’s certain that your device will have adequate power with a reliable 650 watts PSU. However, if you’re constructing a gaming setup with an RTX 3080/3090 or desire to prepare for the future (which is nearly impossible), you should select a stronger PSU. Take caution as increased power brings a higher possibility of excessive heat.

When you plug in a 6-pin GPU with an 8-pin connector, it draws a lot of power, more power than it was meant to be! This will create a load on your PSU, and you may possibly witness a system failure along with erasing all the data. Thus, it is better to replace your PSU with an upgraded one. Final Words An 8-pin GPU cable is a power connector common in most high-end graphics. These connectors usually have a 4.2 mm pitch that can seamlessly offer a power supply of 150 watts. If you connect a graphics card with an 8-pin connector, the maximum power supply you can draw is 225 watts. You will get 75 watts from the PCIe x16 slot and 150 watts from the eight-pin connectors. An 8-pin GPU Cable You shouldn't be able to switch between them - the square and rounded off connectors are arranged such that you can't. Note the top left connector on the EPS 12V is squared off, while that on the PCIe is rounded off in the image before.Essentially differences like that are to prevent you from plugging in a PCIe connector into a EPS12V. There may be other differences, but I don't have these connectors on hand/ First of all, take out your PSU and unscrew its panel, then you will find several wires and drivers installed within your PSU, now you have to spot your motherboard, especially the PCIe slots (PCIe slots are those slots that connect your PSU to essential components)The most recent example would be NVIDIA 3000 series development by NVIDIA, and it came along with 12-pin connectors to draw the power supply needed by the GPU. 5. Can A 6-Pin PSU Connect To An 8-Pin GPU Connector? Although the math might not seem right when compared to the 6-pin connector, the 8-pin connector can deliver 150 watts to a graphics card. If the GPU requires more than 150 watts, it will come with an 8-pin connector or two 6-pin connectors. The adapters and converters help users connect the new-age GPUs to older PSUs without any challenges. You can easily use these adapters to connect to achieve compatibility with high-end GPUs. These adapters are often termed Molex adapters/Molex converters. Here are some adapters or converters that you can use to compatibility with your desired pin connectors. 1. 4-Pin Molex To 6-Pin PCI-E Adapter Cable

The graphics card that easily harnesses the power from a 6-pin connector is GTX 1060 and GTX 1650. These two graphics cards have a power requirement of 120 and 100 watts, respectively. In many cases, Graphics cards have two 6-pin connectors. Two six-pin connectors will offer 150 watts of power, and the PCIe x16 slot will offer another 75 watts. Thus, the total power they would get is 225 watts. What Is An 8-pin GPU Cable?When gamers build a PC, power consumption is one of the most imperative factors to consider. However, users often overlook this factor with top-tier graphics cards. To achieve an immersive playing experience on their PCs, they install top of a line graphics cards. These graphics cards impose an excessive burden on PSUs that increases hassles for gamers.

Now slide the 8-pin GPU connectors to your six-pin PSU and abridge the remaining two pins, then finally connect the PSU and turn it on for a test run. 3. How Do I Connect My GPU To My Power Supply?This cable uses a double 4-pin connections and adjusts them to an 8-pin connection. 4-pin to 8-pin is something that will probably be handy with advanced graphics cards. 6-Pin to 8-Pin PCI-E Adapter Cable Connecting a 6 Pin PSU into an 8-pin GPU involves many risks, and it can include fire hazards as well. It is because; when you connect a 6-pin PSU into an 8-pin GPU, it will attempt to extract immense power, more than its cable rating. In such cases, it can lead to the burning of cable. Apart from that, it can also lead to deleting all your crucial data.
