Riser and rtx 3060 ti on splitter?

So I’m about to build my first mining rig on hiveos with 4 3060ti’s and I’m confused if I can use a 8 pin to a 2 x 6+2 pin to power my riser and gpu. I’ve been overclocking my gpu for a couple hours and the lowest I can get is 180 and I’m pretty sure thats 180 watts (I’ve only tested one gpu) so I’m not sure if I can connect the card and the riser on the same pcie cable
