My old Corsair HX620 has 6pins on the PSU and 8pins on PCIE cable. Modular cables I mean.
6pin can deliver the same as 8pin.

pci 6 pin provide same power as 8 pin
the extra 2 pin up to 8 are useless ground from same common ground as the others
the 2nd 12V pin from 6 pin connector is not in use on vga PCB's so only two 12V provide power;these two provide min. 120 W not 75W
the three 12V pins from 8 pin connector ,all used on vga PCB, provide more than 150 W somewhere in range of min.220 W
as i see industry standards underrated all and is a big margin which allow the OC
before anyone ask how two 12V rail provide 120W:
molex 12V rail is rated 60W
2 molex to 8 pin adapter has two molex 12 V rail..... so 2*60W=120 W but 8 pin is rated 150W so it can draw 75w from each rail....

I suggest you get a proper PSU. So no 6 pin in a 8 pin. Not even an adapter

good PSU shouldnt require you to use a 6 to 8 pin adapter.
