That looks like the CPU connector. Unfortunately, if your PSU does not have that connector
The 4-pin connector is ATX12V / half-EPS12 for the motherboard. The 6/6+2 connectors are PCIe AUX / "GPU" power cables, not CPU.
PCIe AUX is much newer than ATX12V so a PSU that has PCIe power must have ATX12V/EPS12. Though it is possible that some PSUs only have a solid 2x4 EPS12 instead of one that splits into 4+4. Modular PSUs in particular often have separate cables for ATX12V and EPS12 or one EPS12 with 4+4 connection and one solid 8-pin.
