Hello,
Over a year ago, I used to mine just for fun with GTX 970ti. I stopped mining for almost a year. Recently, I purchased a GTX 1070 GPU and installed Nicehash 2.0, to "test" my new GPU. I was surprised to see that it can only make $1.40-$1.50 per day without overclocking (up to $1.70 with overclocking). I also tried to mine ETH and ETC in Nanopool, but the results were much worse.
Since the energy cost in my area is relatively low (~$0.07), I was thinking about building a small mining rig with "Titanium" or "Platinum" PSU and 4-5 GTX 1070/1070ti GPUs. My goal is to be able to mine ALT coins for ~$10 per day. I'm just not sure if a ring with a few GTX 1070 GPUs will be powerful enough nowadays for mining. Any advice would be greatly appreciated!
It's powerful enough for TODAY. But for next month, who knows? There seems to be a ton of risks factors facing GPU miners right now and i feel the GPU mining market will become obsolete once mining matures.
You probably don't need Titanium rated PSUs, along with it's hefty pricetag. The platinum PSUs are already good enough as they are.
