Don't skimp on cables. Don't use a 6/8pin GPU power adapter from SATA or Molex. Even 2xMolex to PCIE isn't a smart idea.

This rig has individual PCIE cables for each GPU and riser. Sorry but I fail to understand which cable is wrong.

And then, a few posts later, you post links to 6 Pin PCI to SATA Power Cable with the question of whether to use them or not?
I really don't know what you don't understand here.

I understand that I should not use the SATA power cable.
I am trying to see whether I could still use the corsair PSU. It has 6 pin slot available and should I try to locate 6 pin to PCIE power cable ?

You can use a second psu if your first one is out of connectors...or near its limit on total power...but you need to follow a few basic rules for dual psu.... (atx psus...likewhat you are using now)

You can use a 2pin y cable that will start both psus at same time. like this... https://www.amazon.com/Qaoquda-Power-Supply-Adapter-Motherboard/dp/B078W4H16S/ref=sr_1_1?dchild=1&keywords=dual+psu+y+cable&qid=1610902119&sr=8-1

You must connect all mobo connections to one psu... (cpu / molex )

Each gpu & riser must be from the same psu. Never gpu from psu 1 and riser its on connected to psu 2....that is a nono.

Thats pretty much it.

You can also do it with your psu (again only it hooked to motherboard)
Then power gpus/riser combos until the psu1 is full. Again never combine psus to a gpu/riser combo.

Then for second psu you can use something like a server psu with a break out board....

with an adapter like

And you will have a lot of 6 and 6+2 connectors and 1200ws added to your rig.
