Yes, it is correct.

I'm not entirely certain about the details already mentioned. Therefore, I'll add more information. For fans, it's unclear whether you're using an AIO or an air cooler; if you're using AIO or planning to use one in the future, verify which fan headers correspond to the pump. Most mid-range and higher-end motherboards have compatible fan headers for regular fans and pumps, but this isn't guaranteed. Always double-check the motherboard specifications.
Regarding the GPU, it requires a 3-pin PCIe cable, while you can use two 6+2 pin cables on one PCIe connector and another cable for the third slot. It's better to use three separate cables if possible. Personally, if your PSU only provides two PCIe cables, I opt for a dual 6-pin to 8-pin adapter. This setup ensures equal power draw across all cables. The reasoning is to avoid uneven load distribution compared to using just one cable for two slots on the GPU. I hope this explanation is clear enough.
