Port number varies from power supply connection to CPU port.
Port number varies from power supply connection to CPU port.
Hey there, I wasn't sure if this fit the right place. Hope it's okay if I share this. I just got a new modular power supply and the CPU connector doesn't match the port on my motherboard. Is this normal? Both are 8-pin connectors. The motherboard port is square, while the connector isn't—top row is square, bottom is not. The PSU is a Corsair CX650M and the board is an MSI B85-G41 PC Mate from around 2014. I saw a similar issue with a CX750M using a faulty cable, but it worked out. The new cable fits, though the shape difference is a bit concerning. I'm not super tech-savvy, so if something isn't clear, I might need help.
The existing cable for your PSU, which splits into two 4-pin connectors, doesn't match the EPS 8 pin connector on your motherboard. Have you checked if rotating it could help?
Check if your PSU or motherboard meets this requirement. Do you have a photo of it?
Confirm if you're selecting the EPS cable instead of the PCIe cable.
According to the PSU's perspective, the appearance suggests the left side of the two 4-pin connectors is standard, while the right side has irregular shapes instead of squares. This causes a slight fit issue despite compatibility.
Located the update now, it's an MSI B85-G41 PC Mate, probably around six years old—so it's a bit worn out.
It seems like you're explaining how the connector works. For compatibility, the second 4-pin section fits into a separate 4-pin EPS or just next to the first one. Just connect them together and plug them in—make sure to go in one direction only because the left side is keyed.
That's great to hear! I appreciate it. While I usually avoid tech discussions, I find it fascinating how quickly and effectively people can help each other.
