Newbie questions...

I have 3 Apollo BTC miners up and running with no issues. Full node downloaded in 1.5 days. :-)

I have a controller and 2 standard units. I am running in turbo mode. Hash rate is ~3.1  I see all 3 in the dashboard.
Is there any way to increase the power on one of the standard units that is running with a 500W power supply? The other 2 are running the 200W PS. If they all need to be managed by the same rules, I will buy 2 more 500W power supplies if that allows me to increase the hash rate . If I do that, how do push all three to the 3.8TH/s limit? Do I need to adjust the power in "Custom Miner Mode"? If so, how high should I go?


Thank you in advance for your help/advice.

"*Our FutureBit 200W power supply is limited to ~ 3 TH/s, 3.8 TH/s is only achievable with an external > 300 watt power supply"

+1 for this question. What are recommended settings for 3.8 TH/s?
