Hey, thanks for replies guys appreciate it very much.
Now I have an idea what psu to purchase for 4 or 6 rig setup.
It's a shame because I still have 1x 8pin connector & 2x 6pin connector "FREE" on PSU. If only these could be used to fire up another GPU, that would have been awesome!

Next part. Fans. I'm currently using : PRIZM 120MM ADDRESSABLE RGB CASE FANS - FIVE PACK for my 4x Radeon Vii rig, they are working great, no issues, I think it has auto feature where it increases RPM depending how hot the rig is running.

Do you guy's think this is a good brand? My mining rig can handle 5x 120mm fans.

What do you think?
