Recently We Develop the Overclocking Project for Antminer S19pro 110t and S19 95t with Overclocking Power Supply 6000w/8000w.

S19pro 110t Can Overclock to About 150t+ in Oil by 6000w Overclokcing Power Supply

S19pro 110t Can Overclock to About 180t+ in Oil by 8000w Overclokcing Power Supply

Especially, We Also Can Provide the Overclock Control Board with No Commision.

Meanwhile, We Also Can Provide the Immersion Box and Cooling Oil.

Anyway, We Could Provide the One-stop Service from the Design and Installment.
