You should connect both the 4+4 and the 4 pin to your CPU. The setup depends on your motherboard design, but typically you need all three pins for proper power delivery. Using just one half won’t work. Make sure you match the pin configuration with your specific CPU model.
Yes, you can connect one of the 4-pin cables directly while keeping the other end attached.
It's fine to proceed as planned. However, you're right to note it's not necessary. I only use a single 1x8 pin, and these CPUs consume no more than 120 watts, allowing the connector to handle an additional 100 watts. Feel free to adjust your setup as needed—it will still function.
