In such cases, the graphics card draws 75 watts of power from the PCIe x16 connector, and the additional 75 watts of power get extracted from the 6-pin connectors. One hundred fifty watts of power supply is precise and more than expected for several GPUs. But there are also graphic cards that draw 320 or 750 watts of power. These are usually high-end power-hungry GPUs that demand power for superfast data transmission. An entry-level graphics card needs 150 watts of power supply through the motherboard for running seamlessly. In contrast, the standard PCIe x16 slots only offer you 75 watts of power. So, if you expect a desirable performance from your PC, you need highly efficient GPU power connectors.
6-Pin, 8-Pin, and GPU Power Connectors - Difference Between 6-Pin, 8-Pin, and
Nothing can happen as most GPUs can’t boot without noticing a full 8-pin connector. Pulling many watts with two pins less isn’t safe, especially under full load. If the card, by any chance, boots, it may be unstable as it doesn’t receive the power it needs. Conclusion 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. I was hoping to upgrade my AMD Radeon 5850 (2x 6 pin) to a Rx480 8GB AIB board (probably Sapphire Nitro+) but this requires an 8 pin plug. However, to be safe, if your PSU doesn’t have an 8-pin, buy a new PSU rather than risk using adapters. A PSU without an 8-pin adapter cannot output much power on the 12V rail for the CPU and GPU.Are you confused between 6-Pin, 8-Pin, and 12-Pin GPU power connected? If yes, then this article is for you. Below in this article, we have shared everything you need to know about those types of power 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 As mentioned earlier, the 12-pin power connector is the latest technology necessary for NVIDIA’s 3000 series graphics cards. Because there were relatively few PSUs with a 12-pin power connector on the launch of the 3000 series, NVIDIA included a dual 8-pin to 12-pin adapter with its product. SATA to 6-Pin PCI-E Adapter CableThe way you say it's from a prebuilt makes me nervous recommending a new PSU too, as there is a chance it uses not standard plugs for the motherboard and such.. Otherwise a 60 USD or so PSU would be more than plenty for most commodity system with an RX 570 (think a CX550 or so PSU).
6 pin to 8 pin vs single 6 pin to 8 pin [SOLVED] - Dual 6 pin to 8 pin vs single 6 pin to 8 pin
Adding one line a piece for ground, 3.3, 5, and 12 volts came with the new 24-pin connector. The extra pins made the power cables useless; thus, most ATX 12V don’t contain them. The 24-pin connector is polarized; therefore, you can only insert it pointing in the correct direction. What is the ATX 12V connector used for? Several CPUs come with multiple numbers of PCIe x16 slots. This enables users to harness more GPUs to the system. However, it eventually increases the power consumption of the whole system. The issue is "some" adapters are crap. But if it can be avoided, do not use one. Its just one more connection that can degrade over time. I have used them with 90 degree in a tight case but I try to avoid them.This ATX12V connector usage is by many processors, such as Intel or AMD. What’s the purpose of the 4-pin power connector? There are even some exceptional cases where the GPU will have two 8-pin connectors. By adding the numbers together, we get a total of 375 watts, which is an extreme amount. In addition, you still need to power the CPU ( another big energy consumer) and the rest of your PC’s components. It looks like it has 17 amps (204 watts) available for the GPU. Rather disappointed that they didn't use a 6+2 cable for this PSU. The PSU should supply you with the power that you need to run your system, (at least what you've told us of it) (hint, hint, fill out your system specs) but Seasonic may have limited your ability to do so with the connectors provided. W1zzard tested a RX-570 4GB and it maxed out at 180 watts. If you subtract the 75 watts that the card can pull through the PCI-e slot, that still leaves 105 watts to come through that 75 watt rated 6 pin. I have no idea if Seasonic has over current protection on those connectors. Connect a standard 6-pin PCI Express power connection on the Power Supply to 8-pin ATI and NVidia video cards
