Hello, welcome to your first PC build! You're checking compatibility before anything else. One 8-pin CPU connector works fine with both your PSU and motherboard, but the second one is a 4+4 socket. Only one of the four pins fits on the motherboard. Are you making a mistake? Your motherboard is the Z790 MSI TOMAHAWK DDR4 model with a 1000W PSU. The CPU you're using is an i7-13700K. You don’t need both 8-pin connectors for this chipset—just one 8-pin should suffice. The 4-pin connector has only four pins, so it won’t support the i7-13700K properly. The design of the pins might be a manufacturing issue. Both connectors have CPU slots on the sides, but the 4-pin version is likely incompatible. Double-check the pin layout and consider using just one 8-pin connector for safety. If you're unsure, consult the manufacturer’s guidelines or a tech forum. You're doing great, keep going!

One 8-pin works just fine here. At default settings the component doesn’t exceed 300W, which is more than enough for a single 8-pin. I’m unsure why the second 8-pin isn’t functioning either—it shouldn’t be an issue.

The second image shows the correct connector, with the bottom-right pin shaped like a rounding. This doesn’t match the standard square shape expected for the Mobo Plus. I’m unsure if other connectors follow this design, but it seems unique to this model.

presumably the links should align correctly.

One of the four pins might have a channel or part inside the plastic, and one section could move into the other to create the eight-pin connector. The size of each pin may not exactly match the motherboard header pins, but the plug should still fit. PSU manufacturers adjust the plug’s keying so that one of the two four-pin pieces can connect to a four-pin CPU header on older boards.
