Can I rely solely on the 6 + 2 split-end section of a PCIe cable for an 8-pin GPU?

Typically, the initial connector is designed for greater current capacity due to its thicker wires and HCS construction. Therefore, it's preferable to select the first connector on the cable rather than using a daisy-chained one.

The image of this cable is located here, and I am comfortable using a soldering iron along with all the necessary tools.

I planned to rely solely on the 6 + 2 split-end design to drive an 8-pin GPU, since it would simplify cable organization in my setup.
I wanted to know if opting for the split-end connector would change the process compared to using the alternative 6 + 2 connector.
Please let me know if you need more details.

I chose the first connector on the cable. It seems a bit awkward having the split-end connector inside the case, but it's not a major issue.

Use a 2-channel cable with an 8-pin connection to link an 8-pin GPU port and an 8-pin GPU port via a modular power supply.
