You can use just one of the 8pin ports; it’s not necessary to power both simultaneously. Your setup should work fine with a single power source.
You can use just one 8pin connector. The EPS CPU power cable for a single 8pin can provide more than 200w of constant power. One 8pin is sufficient to run two 9800X3D models; I’ve overclocked one on one cable and it works fine. @Cringe_Master245 All good, let me know when you need anything.
You need a way to utilize your existing GPU with an 8-pin port, even though the only available one is connected to the motherboard. This solution is just a temporary fix while you search for a 5070 Ti.
Use a different cable for the GPU. Avoid combining the CPU power cable with the GPU PCIe cables—they appear alike but serve distinct purposes. These are the included cables with Be Quiet. RED stands for CPU power, GREEN for graphics card power. The 12VHPWR is suitable for contemporary GPUs such as the 5070 Ti.
