Powering Rx 580 8 pin vs 8pin + 6pin

[richpress]

Hello all,
so i'm building my first rig with 6 Sapphire Rx 580 nitro + , I notice they have 2 power connectors one 8 pin and one 6 pin, I'm using 2 cooler master 750w PSUs which offer me 6+2 pin power cables
the question is: is it safe to use only the 6+2 cable to power each GPU ? even if I plan to use the overclock bios switch ?
Thanks !
