If you are wondering why you haven’t been able to get your hands on Nvidia’s latest RTX 3080 GPUs, it's probably because crypto minors have bought hoards of cards for themselves. That is certainly the case for this particular crypto miner who managed to secure 78 RTX 3080 cards.

The mining rig by this minor has been pictured and been widely circulated on social media. The rig was created by Simon Byrne and has aptly named his rig ‘Berta 2’. The GPUs have been illuminated with colour RGB backlight according to reports by Tech ARP.

If you are wondering what kind of revenue a setup like this would generate, it is being reported that the rig can earn $20,000 or upwards of Rs 14 Lakh each month. If we look at how much Ethereum is worth today, the rig can generate around $6.35 to $9.15 per day including the cost of electricity. Tech ARP estimates this particular rig will run $1,444 per month just to power it and additional money for cooling costs. Since Byrne lives in Las Vegas, he could generate anywhere between $15,000 and $21,000 in income.

Since Byrne has invested in 70 RTX 3080 cards, the initial cost is quite large and will take around six months for him to recover. The rig itself costs around $100,000 as each graphic card starts at  $699. However, if you take into account the fluctuation exchange rate of cryptocurrency, his return on investment could take longer than six months. 

However, Simon himself has also commented on his rig where he gives details about his setup. Apart from the 78 RTX 3080 GPUs, the rig also uses GeForce GTX 1080 Ti graphics cards for a total of 143 GPUs. He mentioned that his net profitability is $900 per day which makes him earn up to $27,000 US per month. He also mentioned that he achieved a return on investment in under 2 months.
