Check the manual that came with it, if it says three PCIe 8 pin (6+2) cables, you better contact the seller or Corsair to get what you paid for.
Be noted, there are different versions of this PSU, maybe also with different cable listings
Yup, the newer version only has two cables, but it also says three times an EPS/ATX 12V 8 pin (4+4) which I don't understand. I don't know any MB with three EPS connectors, two at most.
From my point of view it should be 3 x PCIe and 2 x EPS, but the only way to make sure is to contact Corsair support.

You can search specific cables on the Corsair site. They will tell you if it's compatible or not.
I bought this to connect my 4080 super to my RM850X. It works fine.

Corsair sells a 2x8pin to 12VHPWR cable, I'm not sure why you would buy anything else... Powers a 4090 easily will do just fine on a 4080.

I avoid frequently returned items on Amazon, it's also never a good idea to mix cables from different power supply makers.
Honestly you must have got lucky it didn't kill your card/power supply.

Good for you, I'm glad it worked out.. Also glad you linked it for the OP to at least look at it.
Still wouldn't touch it personally but every person has to decide that for themselves.

It should run fine on two cables, using the pigtail of the second connector into the third socket.

Don't buy from a 3rd party, always go direct to the company for cables, in this case - Corsair
You have two options.
1/ If you going to use the patch cable that came with the GPU then you need this cable
Premium Individually Sleeved PCIe Cable (Single Connector) Type 5 Gen 5, Black
Upgrade your CORSAIR Type-5 power supply’s cables with CORSAIR Premium Individually Sleeved Type-5 Cables, made with flexible triple-layer meshparacord sleeving for a professional look.

2/ This cable will allow you to go direct from the PSU to the GPU thus doing away with the patch cable that came with the GPU.

According to Corsair's own chart. this should be compatible since its a Gen 4. Corsair tends to go by 'type' instead of 'Gen'.
With that said I would still prefer to get a cable directly from corsair. Its just safer.
So can I just directly connect one end to psu and the other end into one of 3 pcie ports on my gpu?

It should function like any other corsair cable
How does your GPU have 3 PCIe ports? A 4080 has a single 12VHWPR connector. The included adapter has 3 8-pin PCIe jacks.

Why are you making this hard ... ?
Examples for RTX 4090 - it's the same for an RTX 4080
Direct to the PSU with this cable below (Corsair's own cable), this option does away with the patch cable above that comes with the GPU.
