I'm building my first PC and I'm a bit confused about the power supply unit (PSU) I got. It's a 750w SeaSonic Core PSU, which includes a cable that has 12 pins that split into two 8 pin connectors. However, my NVIDIA 3080 graphics card has three 8 pin power ports, so I'm wondering if I need to buy another PCIe cable or if I should get a new PSU altogether. The PSU has one 12-pin slot and three other CPU/PCIe slots. What should I do next? Should I buy a separate PCIe cable for my GPU, or can I manage with what I have?

You'll need a compatible 8-pin to 8-pin cable for your PSU since not all cables work across different models—even from the same brand! You won't need three separate cables; just use the two that came with your PSU and purchase one more 8-pin cable.
So, I can just grab the 8-pin from the supplier's store, right?
