Hello, I see you're experiencing an issue with your PC not turning on when the CPU 8 pin is connected. Let's go through this step by step. Your system includes an Intel i5-9600 K with a 16GB RAM setup and other components like the GPU and Wi-Fi module. Have you checked if the power supply is stable or if there are any error codes displayed? It might help to rule out power issues or hardware faults before assuming a motherboard problem.

Your system won't start without the 8-pin connector, which supplies power to the CPU. Make sure you're using the correct pin on your motherboard—most people mean the one at the top left labeled as 8 pins.

The first eight pins on the left are the one you’re referring to, but when linked to the power source there’s no electricity reaching the device.

It means you can start a Windows system and everything functions properly, or that the fans and lights activate correctly. Make sure you're talking about the highlighted connector.

I'm talking about the highlighted connection. When I say it functions properly, the fans and GPU lights up and start spinning.

It connects four pins together to form a complete circuit.

Yes, I know that the "8 pin" is actually a 2x4 connector. Using just one 4-pin cable won’t work properly. Make sure you have the right cable—something labeled "CPU" or similar—and verify the pinout matches your board.

This 8-pin connector is actually 2x4, and connecting just one of the four 4-pin sockets gives identical outcomes.

It seems like you're experiencing no power, and you're unsure if a specific pin is the issue.

Original PSU cables? You can attempt to put them together outside the case, like on a motherboard's box, and see if you can start up.
