It would be great if those psu's can handle two S9 ...
But those PSU's are rated to 2400 watts , its way overkill for your power needs for one S9 . Of course much cheaper than
EVGA SuperNOVA 1600 P2There is the Specification form Bitmain website about S9 miners power usage for different batches :
Power Consumption
1127W (11.5TH/s batch),
1225W (12.5TH/s batch),
1274W (13TH/s batch),
1323W (13.5TH/s batch),
1372W (14TH/s batch)
(at the wall, with Bitmains APW3 PSU,93% efficiency, 25°C ambient temp). Expected discrepancy of +10%
