You should include both cables for the i5-13500 installation.
The power supply includes two cables for CPU power, with 2x PSU connectors that can be divided into 2x4pin versions. You attached the 8pin version, but you're unsure about the 4pin slot. You've split the cable and used it as the other connector, leaving the remaining 4pin unused.
You don’t have to include the 4-pin connector since the 13500 will operate without it, though you can install the 8-pin version. If you choose to add the 8-pin, simply keep the remaining 4-pin unconnected.
Sure, just to clarify—you’re dividing the 8-pin connector into two sections, using only the 4-pin part and keeping the remaining 4-pin on the back of the case.
