RM850e Cables

[Chris2k121]

I've already emailed Corsair about this around 3 or 4 days ago but I haven't received a response. I recently bought a 3090 and didn't realise it had 3 power connectors. The RM850e comes with a PCIe cable with a single connector and also one with a double connector. I've read a bunch of times that it's a bad idea to run the double cable on a high powered card, so not going to risk that. My question is - which PCIe cables can I use for this PSU? I have a spare PCIe cable from a different PSU, but looking at the connectors, they're pinned differently. I didn't even realize there were different types until I ran into this issue.

Thanks for any help.

normally you'd look in the cable compatibility chart, but nbody updates it.. so the RMe isn't there

That said, type 3 hasn't been used in years. All current PSUs are type 4, and only the recently released RM shift introduced cable type 5. So, there's 99,9% of chances your PSU is type 4

Anyway.. for all cables except motherboard 24 pin, type 3 and type 4 are identical, so that's that.

Any type 3 or 4 PCIE cable will do.

The RMe PSU uses our Type 4 cables. In order to correctly power the adapter for your GPU, you will need to utilize a single PCIe cable from the PSU per 8-pin connection on the adapter. It is never a good idea to mix cables between PSUs if you are unsure of compatibility, and its never a good idea to mix cables between different PSU manufacturers.

The spare I have is from a Corsair TX650M. This cable has "Type4" printed on the side and is a double connector. As I said previously, the reason I'm unsure is since it's pinned differently to the 2 cables that came with my 850 I currently have plugged into my 2700. On this spare cable pin 6 is missing. On the other 2 currently in use, pin 7 is missing. So it'd be okay to use this cable?

Sorry if I'm asking n00b kinda questions, I just don't want to cause a fire or damage anything.
