Take a look at this crypto-mining rig powered by 78 GeForce RTX 3080 graphics cards, and find out why crypto miners are buying graphics cards by the pallets!


Crypto Mining Rig With 78 GeForce RTX 3080 Cards!

Can’t find an affordable GeForce RTX 3080 graphics card? That’s because crypto-mining is one of the reasons why there is a shortage of graphics cards worldwide.

Here is a crypto-mining rig being built by Simon Byrne, using the 78 GeForce RTX 3080 graphics cards arranged in an array of 13 x 6 cards.

With a power consumption of 300 watts per card, that’s crypto-mining rig would require at least 23.4 kilowatts of power to run, and a lot of air-conditioning to keep them cool!

Update : This GeForce RTX 3080 mining rig is almost operational!


How Much Money Can This RTX 3080 Crypto Mining Rig Make?

Just how much money can Simon make from this crypto-mining rig?

Officially, RTX 3080 cards start at $699, but due to the shortage of cards, they are now selling for about $1,199 each.

So the cards in this rig alone would cost approximately $93,522. Let’s call it a flat $100,000 for the whole rig, plus power supplies.

The average commercial electricity rate in Las Vegas (where he’s based) is 8.43 cents per kWh. So electricity should cost about $1444 per month. Let’s make that $2166 per month (+50%) to account for cooling costs.

Each GeForce RTX 3080 has a hash rate of 83.57 MH/s using the Ethash (Phoenix) algorithm, which should generate approximately 0.22236870 ETH worth US$165 every month.

So the total rig of 78 cards should generate 17.3447586 ETH worth $12,840 per month. Deducting electricity costs, that’s a net profit of $10,674 per month or $128,088 per year!

That’s an incredible ROI of 10.7% per month, which means he recovers the cost of the entire rig in just under 9.5 months.

No wonder crypto miners are buying up graphics cards by the pallets… at the expense of PC gamers all around the world!
