Antminer S21 Pro

[FP91G]

The s21 xp earns $13.50 and at 10 cent power it burns $8.40

Thus

13.50
- 8.40
$5.10 after power.

That is 1800 a year.

But it does cost 7,000

So that means it will take 4 years to make money.

This?

Such an ASIC also needs an additional water cooling system, which will have to be bought or made, but at a price of 5 cents per kilowatt, the payback looks good.
Now it is necessary to use the latest generation of ASICs to have maximum profitability.

no i meant aircooled version.

not the liquid cooled three phase one.

the aircooled one is above i have four of them.

There are so many models of ASICs with air, water and immersion cooling now that it is very difficult to immediately understand which model is being discussed. I have always been a supporter of air cooling, as the easiest to maintain and proven by 10 years of experience.

also if you have 1 phase 240 volt

refit to three phase is costly.

I purchased a fifth s21 xp it will go on line next week.

Explain what the problem is with a three-phase system if you have your own generator? In Russia, for example, the generator is shared among a certain number of houses, and to connect 4 cables instead of the standard 2, we need to obtain a special permit. This adds extra control, where current limiters are installed on each wire to restrict power consumption to no more than 5 kilowatts. There are no restrictions with a single-phase connection. The thickness of the wires limits the power consumption
