Error message about incorrect PCIe/CPU connection.
Error message about incorrect PCIe/CPU connection.
This morning I had to make some changes on my PC and noticed something that made me realize I probably connected the wrong slots on the motherboard and GPU. As shown in the picture, it’s an RM750e with PCIe/CPU slots visible. I’m guessing the one on the left is for the GPU and the one on the right is for the CPU… I think I messed up. The connection from the PSU PCIe slot to the CPU on the motherboard was linked to the CPU, while the one connected in the CPU slot on the PSU was linked to the GPU. I checked the manual but found no clear explanation about whether the PSU slots are actually different (PCIe/CPU meaning left is for GPU and right for CPU). I’ve used it for a few days without any problems, but I’m confused about how I mixed up the cables. I feel really foolish now and am worried I might have damaged something. I’m also upset because the RM750e didn’t clarify this, which could be open to interpretation. This makes it hard for me to decide if everything is okay or not. Any advice would be super helpful since I need to fix this quickly so I can start my exam. Thank you for your support!
Not all four PCIe/CPU connections are suitable for Ethernet. You may combine these four ports in any order between the CPU and GPU, depending on your needs—such as using just one CPU port but three GPU ports, or having two CPU ports if the motherboard requires it. The same applies to SATA/PATA; you can connect any mix of SATA or Molex cables into those four ports.
Correct, both the CPU and GPU require +12v and a ground connection, allowing them to share the same power supply outlets on the PSU. The differences lie in the end of the plug connected to the graphics card motherboard, which will have distinct keying.
For the GPU, you typically receive a plug with 6 pins plus a small 2-pin connector for side attachment, or an 8-pin plug as with a solid model.
For the CPU, the cable generally comes in 2 four-pin connectors that can be joined to form an eight-pin configuration.
Thank you! I really appreciate you helping. I kinda figured that it was fine but since I dont know a lot, I felt that I could be wrong. Also am I crazy; it can be interpreted differently right (i.e PCIe/CPU means the ports on the left are for the GPU and the right are for the CPU)? I overthink a lot so maybe I am just doing that here.
