I'm not sure if I did the PSU connections right on my new build.
Hi!
I've just built my new PC but haven't powered it on yet because I'm unsure if I connected the cables to the PSU ports correctly.
The PSU is
750W Seasonic Focus GX 80+ Gold - SSR-750FX3
I have the following components:
Mobo: MSI PRO B650-S WiFi
CPU: Ryzen 5 7600X
GPU: RX 6800
1
. GPU Connection:
- I used two separate PCI-E cables from the PSU to the GPU.
- I did not use a single 8-pin PCI-E cable with two split 8-pin connectors for the GPU.
Should I keep the GPU connected with the two separate PCI-E cables or should I change it and use just one PCI-E 8 pin cable that has 2x8 split ends for the GPU ports?

. CPU Connection:
- I connected both 8-pin CPU connectors to the PSU.
I've noticed some people use only one 8-pin cable, so I'm unsure if both are necessary or if only one should be used.
3
. Port Arrangement:
Should CPU and PCI-E cables be plugged into adjacent ports? Or should CPU and PCI-E cables be separated and not plugged next to each other? e.g. the two 8 pin CPU ports on the PSU should not be plugged next to each other? Same for the PCI-E.
I've included a screenshot of the PSU ports with an explanation of how I plugged in the cables.

Here’s how I’ve connected the cables (please refer to the attached image, where I’ve marked how I connected the CPU and PCI-E (GPU) ports with red text):
To the top CPU/PCI-E port (next to the motherboard port), I connected one of the PCI-E cables for the GPU.
For the three 8-pin CPU/PCI-E ports at the bottom, I connected the two 8-pin CPU cables to the first two ports (left to right) and the second PCI-E cable for the GPU to the third port.
I’d appreciate your feedback on whether I’ve connected the ports correctly or if I need to change anything.
Thank you!
From the way you've described it, it seems clear that you've connected to the PSU side using the correct cables and made the proper connections on the devices side, following the correct procedure.
The standard is to use split connectors, but the advice is to have a separate cable for each GPU connector, which I followed as you confirmed.
Your PSU provides the required connectors to link with both EPS connectors on your motherboard. Unless you plan to overclock or install a Ryzen 7 or Ryzen 9 processor, and prefer not to manage cables or deal with additional EPS connectors, you can skip this step as mentioned in my earlier post. However, the first EPS connector (CPU_PWR1) must still be connected.
It works with certain contemporary high-performance graphics cards. Your RX6800 requires two 8-pin connectors, meaning you won't need to connect the 12V-2X6 cable to your power supply. Keep the cable available (and marked with your PSU model) should you upgrade to a more demanding GPU like RTX5090.
