I've seen it's possible to get a hash rate of 31-32mh per card using a single 850W PSU (for 6 GPU) after Overclock/Undervolt.
My assumption of this is a good configuration, as it reduces the stress and power consumption for the GPU yet achieving desirable results. Please correct me if I'm wrong.
I’ve no experience with GPU flashing. Any idea where do I start and how can I achieve similar flashing results?
Will there be any risk involved during flashing - such as destroying the GPU?
Your guidance will be very much appreciated.
Thanks!
Personally I would not recommend an 850w PSU for 6xAMD Rx580 8GB card, you should at least know and understand how to properly undervolt your cards and efficient memory modification straps, for 31-32mh undervolt, I doub't it and for a newbie its not easy. there are guides out there to simply do your own modifications and play with straps.

get at least 1000w of psu for 6GPU cards.
goodluck!
