12-Card GeForce RTX 3090 Gigahash Mining Rig!

It seems easy for crypto-miners to get hold of the GeForce RTX 3090 graphics card in bulk.

A crypto-miner is building a compact mining rig that uses just a dozen GeForce RTX 3090 graphics cards to generate over a gigahash per second!

Guntis Vitolins, who recently lost 500 graphics cards in a fire, is using a dozen INNO3D GeForce RTX 3090 graphics cards, powered by four EVGA SuperNOVA G3 1000 watt power supplies.

How Much Money Can This RTX 3090 Crypto Mining Rig Make?

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

Officially, RTX 3090 cards start at US$1,499, but due to the shortage of cards, they are now selling for about US$2,450 each. The EVGA SuperNOVA G3 1000 PSU each cost US$309.

So the twelve cards would cost approximately US$29,400, while the four EVGA PSUs would cost US$1,236. Let’s call it a flat US$31,000 for the whole rig.

The average commercial electricity rate in Ireland (where he’s based) is about €0.2413 per kWh. So electricity should cost about €800 or US$965 per month. Let’s make that US$1450 per month (+50%) to account for cooling costs.

Each GeForce RTX 3090 has a hash rate of 104.48 MH/s using the Ethash (Phoenix) algorithm, which should generate approximately 0.23401064 ETH worth US$312.53 every month.

So the total rig of 12 cards should generate 2.80812768 ETH worth US$3,750 per month. Deducting electricity costs, that’s a net profit of $2,300 per month or $27,600 per year!

That’s a high ROI of 7.4% per month, which means he recovers the cost of the entire rig in about 13.5 months.

This is about 31% lower ROI than the 78-card mining rig that uses the much cheaper GeForce RTX 3080, which pays for itself in just 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!
