Question Where to connect on PSU?

[Devdeep]

It is a few years since I last built a PC. Am puzzled with the PSU and Asus Crosshair VII Hero Motherboard connections to Corsair RM750i PSU. I can see where the 24pin connection goes from MB to PSU but not sure about the 8 pin / 4pin connections on the MB. Using Ryzen 2700X CPU, do I need the 8+4 connections and where does the other end go on the PSU please?

For this power supply model, these are interchangeable for your CPU and your PCIe (GPU). Your cable for your CPU should fit into one of these, and then the other side should be split into 2 x 4 pin (and the cable will likely be labled CPU).

You usually do not need to use both the 8 pin (2 x 4 pin) + the stand-alone 4 pin for the CPU unless you are heavily overclocking your 2700x. However, from what I have seen, there's not much overhead left to get much more out them. So at first just use the one 2 x 4 pin CPU connector, and you shouldn't need to worry about the other one.

Thanks for this.
