CORSAIR - 600W PCle 5.0 / Gen 5 12VHPWR Type-4 Adapter Enough For RTX 4090?

[Bekrah]

I’m using a Corsair RM1000x PSU. 
I’m also running a RTX 4090. 
Will this cable be enough to power it considering it only has two 8 pin connectors?

yes it is.

The only reason for the 4 cables adapter is the old PCIE connector has a power rating of 150W, so they need to use 4 cables to avoid exceeding the specification.

Once you remove those connectors you don't require 4 cables, and only need a cable thick enough to take the current. In fact, the PCIE cables on ATX3.0 is a single cable, with 12VHPWR connectors on each end.
