dual 8 pins single cable

[AlienAmof]

So, i have a corsair cv650 psu 80+ bronze
it has 2 (6+2) pcie connectors attached to a single cable
i know that 8 pin pcie is rated for 150w !! but are these actually 2x  so 300w! or just 1
my question is can i run 2 rtx 3060tis each of them requires a single 8 pin cable (using that single pcie (6+2) cable which is splitted to 2x(6+2) ) ?
my second question is are 2x molex or 2x sata to 8pin ok ?

Gpu: Evga rtx 3060ti sc 
4th gen mobo + i3 cpu
i`m using it to mine crypto ( sorry)

thank you.

Did you look up the power requirements of the hardware? Are you gonna observer the 80% rule or just risk it?

ye i did 650w psu is enough
rtx 3060ti uses around 195w for each while oc, so 400w max for 2x 3060ti
i`m sure  i3 4160+mobo + ssd will not exceed the 650w

Then it wont matter what adapters you use.
