The same S5 boards/chips...
But what about their
new chip, all that 0.3-0.4 Wt/Ghash?....
I hope they at least will offer this "upgrade" boards by the piece, 'cause I think that my S2 case can bear 4 of that boards with Corsair AX1200i Platinum PSU...
I think that such a possibility (to choose desireable quantity of the boards to buy) will be very, VERY convenient for all S2 owners. One would like to buy 3 boards, another (like me, with advanced PSU) would prefer to buy 4 boards... May be someone will buy 5 boards?..
May be, if it's not too late, this new boards should contain one (or two?) additional PCI-E connectors to avoid melting on the backplate?.. Dogie, please do something for us! let Bitmain hear us!..
PSU can be replaced by the owner with some cheap server PSU, it's not a huge problem if he want to occupy most (or all) of available slots on S2's backplate.....
