overclock power consumption

Solution
Way overkill.
Furthermore you'd need a better cooler if you want to OC hard. A Cryorig H5 or Scythe Mugen 5/Max for example
Furthermore I'd go.for a 2 or 3 fan 1070 which will stay cooler, perform better and might be even cheaper

As for the PSU a 550W one will suffice, but go for a quality-PSU from Seasonic or XFX with gold efficiency rating, an EVGA G2/G3/GS or a Corsair RMx
