Right PSUs to run a mining rig (advise needed)

[macmining]

Hello

I need a advice regarding right PSUs to run mining rig.

Mining rig

3x 3060 ti connected through 1x risers (VER009S)
2x 3060 connected through PCI- E 3.0 16X Graphics Card Extension cable (https://amazon.co.uk/gp/product/B087D31XSJ/)

I will have two power supplys

1. corsair gold 850w will run 2x 3060ti 550w (tdp 2x 200w + 2x risers 75w) + 1 x rtx 3060 170w (tdp 170w riser 0w) = 720w in its peak, all cards will be undervolt so it will be using less then 720w following the rull not to run more then 80% of max PSU power 24/7.

2. corsair gold 850w will run 1x 3060ti 275w (tdp 1x 200w + 1x risers 75w) + 1 x rtx 3060 170w (tdp 170w riser 0w) + mobo, cpu, mem, hdd, fans (around 200w) = 645w in its peak, all cards will be undervolt so it will be using less 645w following the rule not to run more then 80% of max PSU power 24/7.

I have read few guides and forums but if some one can double check my calculations and correct me if I am wrong.

Thank you in advance

If you properly limit TDP on those cards when mining, you should be able to easily run all of them off one of those PSUs.

I've got 3x 3070s on a Bronze 750W PSU and it's only drawing 440W from the wall...so it's supplying roughly 375W at 85% efficiency.

Assumimg you are powerimg your risers with pcix, you will lilely run out of pxix cables before you hit your psu limits with 3000 series cards.

The 3060TI's should be running at about 120-130 watts each using these guidelines.
