I never get 100W.
Always about 120W per Card. (MSI GeForce GTX 1070 ARMOR 8G OC with Micron Memory)
Wattmeter says 470W from the wall.
Only 1 ssd connected, nothing else
Setting:
60% tdp
200 coreclock
0 memory
Temp: GPU0: 56C GPU1: 58C GPU2: 48C
GPU0: 419 Sol/s GPU1: 431 Sol/s GPU2: 422 Sol/s
Total speed: 1272 Sol/s
+-----+-------------+--------------+
| GPU | Power usage | Effecincy |
+-----+-------------+--------------+
| 0 | 116W | 3.61 Sol/W |
| 1 | 119W | 3.62 Sol/W |
| 2 | 120W | 3.52 Sol/W |
And very often "Connection to GPU1 lost"
