Question Questions about power comsumption vs profit for mining, and PSU requirements ?

[antonio2000]

so i have a few questions. How much wattage for power supply am i going to need to realistically run the mining rig 6 x 4090's. How much wattage for a power supply do i need and how many if i'm going to need more than one? And how many Kwh is that going to be per card and the power supplies ?

You can no longer mine bitcoin profitably with any GPU based system. There are other coins that you might be able to mine.

If you do not know how to figure all this out in great detail you should not be even considering this. You are going to lose massive amounts of money.

Knowing how to figure out power costs and costs on equipment is the "skill" that lets a small number of people actually make a profit running coin mining. You also have to remember the coins you mine themselves have no actual value. You must trade the for some kind of real money that you can spend. There are huge processing fees involved in this conversion. You must fully understand this concept also to make a profit coin mining.

The guys who run coin mining data centers will actually watch the price of coins and turn their data centers off if the coin price drops too far on some days. The profit margin now very narrow so on some days you make more by not running the machines. The days of free money are long gone, like any other business you do not make money mining coins unless you really know what you are doing.

I don't know what the optimal mining rig would be, but it sure as hell won't be a rig full of 4090s.

Was this not answered in your previous thread?

Question - PSU requirements for a Bitcoin mining rig ?

If I'm running 10 x 4090 GPUs (I know it sounds ridiculous but im thinking about it) what PSU would i need and how many?
