Hey everyone, i am going to be new to crypto mining and are just trying to run by some numbers to see if it is worth it. Have some technical knowledge and have built multiple pc build etc and the mining set ups look easy to get up and running but i am struggling to understand the full hash rate calculation.
I have been looking getting a 6 - 8 GPU rig with either AMD Sapphire Nitro+ RX 580 8GB cards or EVGA GeForce GTX 1070 SC GAMING ACX 3.0, 8GB cards.
From what i understand:
Both of these cards will use roughly 150 watts each.
The AMD cards will get roughly 25-30 MH/s each
The EVGA card will get roughly 28-32 MH/s each
The downside of the EVGA cards is they are much more expensive to purchase.
I am still unsure of the most popular motherboard, processor, & power supply to use at this point. Have seen that Ram does not seem to be that big of an issue as long as you have 4GB. And with the OS i dont know if an M.2, SSD or USB is best.
I live in Australia where the cost of power where i am is $0.25 AUD per KWH.
If i say on average each card will get me 27 MH/s this will result in the whole rig pushing around 162Mh/s and i would expect to power usage to be around 1KW.
When using the below calculator i understand this is all on current difficulty and prices it shows the profit is around $2,190 per year.https://www.cryptocompare.com/mining/calculator/eth?HashingPower=162&HashingUnit=MH/s&PowerConsumption=1000&CostPerkWh=0.25
If someone could possibly help me confirm the above calculations are in the correct range and i have not missed something. Also if you have any suggestions on any hardware i should be heading towards i would appreciate it a lot.
Thanks in advance!!
