I recently started building my PC and ran into an issue with the power supply. I planned to use a 12v to 2 PCIe connector alongside a standard PCIe cable since my GPU needs three PCIe connectors. However, I've discovered that the RM850e (2025) only includes one PCIe connector, even though there's another slot on the power supply. This means I can't power my iCUE link hub that requires a PCIe cable. What are my options to resolve this? Thanks for any help!

You might want to grab another Type 4 PCIe power cable. That could solve the issue without much hassle!
You should actually have more than enough PCIe connectors. The RM850e typically comes with two PCIe 8-Pin cables, and you can use a pigtail from one of them. Just make sure you connect two different cables to the GPU and you should be fine!
What GPU are you using? If it's 300w or under, consider using a pigtail connector. Corsair has stated their Type 4/5 cables are safe for such setups. A 300w GPU like the 5070ti or 9070xt can draw up to 375w with two PCIe connectors plus the slot. If your GPU is heavier, just order an extra cable from Corsair as they usually have them in stock!
I have the 9070xt. I'm not clear on how a pigtail cable could help since I'm already using a 12v to 2 PCIe connector. Plus, the standard PCIe cable isn't a pigtail.
That’s the specification I found too, but it seems like there might be some confusion since you mention only having one.
