On Twitter, he has published one of the craziest cryptocurrencies configurations for mining. @I_Leak_VN shows how a team has done with 10 RTX 3090 graphics cards together with three 1600 W power supplies.

In itself, buying an RTX 3090 graphics card from Nvidia is extremely complicated due to the lack of stock, but it seems that this anonymous Vietnamese user has been able to get hold of about 10 units. Of the 10, 8 are being refrigerated with mineral oil, to keep the high temperatures of this equipment at tolerable levels. Mineral oil is responsible for cooling the GPUs, memories, and VRM stages. To achieve this, they have made a custom liquid cooling kit that works in a loop.
The heat and consumption problem are two critical factors when putting together a system to mine cryptocurrencies. It requires a lot of energy and also in an efficient way to maintain stable temperatures. After all, these computers are designed so that the GPUs work 100% throughout the day.
To deliver the necessary power to the 10 RTX 3090 graphics cards, three 1600 W power supplies are being used, for a total of 4800 W of power.
The RTX 3090 is known to be a very expensive graphics card, but it is also a beast for mining. The card has several advantages, not only for its processing power. It has a really high amount of VRAM memory (24GB) and, in addition, the GDDR6X memory is super fast which, for mining tasks, is essential. We will keep you informed.
