Here are some results for the most profitable algorithms (power usage is for overall system, from the wall with wattmeter) :
ZCash (380 to 435 sol/s). Mem -502, core +135.
65% tdp : 700w
75% tdp: 800w
90% tdp: 950w
ETH (27 to 30mhs). Mem +395, core -150.
65% tdp : 700w
80% tdp : 835w
90% tdp : 920w
LBRY (260 to 290mhs). Mem -502, core +135.
75% tdp: 805w
90% tdp: 910w
DGB-Skein (500mhs). Mem -502, core +135.
65% tdp: 700w
75% tdp : 800w
90% tdp : 940w
You results may vary depending on core and memory clocks. It is more efficient to run at a lower TDP.
