Extreme and CPU connectors for ASUS Rampage models
You're checking your motherboard setup for the Xeon E5-2640 V3. It looks like you have an 8-pin plus 4-pin connector on the motherboard. You're wondering if connecting both connectors to the PSU is necessary, or if using just one 4-pin connector is sufficient. Your current setup uses a 4-pin connector for the CPU and another 4-pin connector for the MB. That should be fine as long as the cables match the pin configuration.
Yes, you connect the 8-pin PSU to the 8-pin motherboard. For future builds with Ryzen 2700X, make sure you have all necessary connectors available.
