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 builds a compact mining rig that uses just a dozen GeForce RTX 3090 graphics cards to generate over a gigaash per second!

Guntis Vitolins, who recently lost 500 graphics cards In the event of a fire, a dozen INNO3D GeForce RTX 3090 graphics cards are used, which are powered by four EVGA SuperNOVA G3 1000 watt power supplies.

How much money Can this RTX 3090 make crypto mining rig?

How much money can Guntis make from this crypto mining rig?

Officially, RTX 3090 cards start at $ 1,499, but due to the lack of tickets they are now available for approx $ 2,450 each. The EVGA SuperNOVA G3 1000 power supply costs per piece $ 309.

So the twelve cards would cost roughly $ 29,400while the four EVGA power supplies would cost $ 1,236. Let’s call it an apartment US$ 31,000 for the whole system.

The average commercial electricity price in Ireland (where it is located) is around € 0.2413 per kWh. So electricity should cost roughly € 800 or $ 965 per month. Let’s do this $ 1450 per month (+ 50%) to take into account the 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 $ 312.53 each month.

The entire rig of 12 cards should therefore generate a value of 2.80812768 ETH $ 3,750 per month. After deducting the electricity costs, this results in a net profit of $ 2,300 per month or $ 27,600 per year!

That’s a high ROI of 7.4% per monthwhich means it will amortize the cost of the entire facility in around 13.5 months.

This is about 31% lower ROI than the 78-card mining rig using the much cheaper GeForce RTX 3080 that pays for itself in just 9.5 months!

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