Hello guys,
First of all if this topic is not in correct section please move it.

I recently started mining I have:

4 Mining Rigs:
GPU: ASUS GTX 1070ti
Motherboard: Gigabyte K3 Gaming Z270
PSU: CoolerMaster 1200w / CoolerMaster 750w

Now my question is what is more better Efficiency VS Power Consumption, let me explain.

7 GPU Mining RIG:
Total Power consumtion - 830w
Total Sol/s - 3300~3350
GPU Temperature - 30~40c
Efficiency - 4,3~4,5 Sols per watt
Power per card - 100~110w
Sol per card - 470~480
---------------------------------------
After Burner:
Power - 60%
Core - +200
Memory - +700
Fans - 60%

7 GPU Mining RIG:
Total Power consumtion - 1150w
Total Sol/s - 3600~3650
GPU Temperature - 45~55c
Efficiency - 3,5~3,6 Sols per watt
Power per card - 140~150w
Sol per card - 510~530
---------------------------------------
After Burner:
Power - 80%
Core - +200
Memory - +700
Fans - 60%




Since I have 4 GPU the total power and total Sol is huge difference, please let me know what do you think its best and WHY ?

Total POWER: 3320 wats
Total Sol: 13200 Sol

Total POWER: 4600 wats
Total Sol: 14400 Sol
