hi

how to measure what power consumption has this server supermicro.com/en/Aplus/system/2U/2123/AS-2123BT-HTR.cfm

It depends on what you run on them. PSU limits it to 2000W

To measure, plug it into a watt-meter

mining with 8 cpu

i dont have it

i want to buy it

Mining will probably get you close to 2000W

and what this means in terms of money if 1 hour power consumption == 5 cents

how to understand how much time i'll need for having my money back after buying that server

5 cents for what? For 1 kWh?

then 2000W is 10 cents per hour

yes

Check any mining calculator: cryptocompare.com/mining/calculator…000&CostPerkWh=0.05&MiningPoolFee=1

I'm assuming 200 kh/s for 8 CPUs

4 * 19875 = 79500

right ?

4 CPUs or 8 CPUs?

8 cpu

you will be losing money

 why?

power consumption is too much

It all depends on how much you will be spending on electricity

if it's 2000W and you pay $0.05 per kWh, it will not be profitable

Thank you for your deep explanation

the last one why you said 200 khs and i found 80

you choosed other cpus?

Yes, I thought it would be more powerful CPUs (Zen2 EPYCs)

Is any profitable configuration for Monero

with power consumption 0.05 cent/hourly

i don't understand how the miners keep mining if there is no profit at all

i trust Monero as the real crypto but devs must do smth about miner profits

Thats up to you to work on adoption

Miner profits are a calculation of difficulty vs marketprice. If difficuly rises with market price, you dont become more profitable

Coins with a lot of profit are more centralized.. meaning, the reason you get more profit is because there is more money is being investmented into buying the coin, than is going towards mining.

Devs don't have to do anything about miner profits

Devs care about decentralized and stable network, not miner profits

Mining is a zero sum game, and only the most efficient miners win

i dont want a lot of .i want yearly 10% back

is too much?

It should be more than 10% with cheap electricity and an efficient rig

it should be 3-4 years ROI, last time I checked

cheap electricity  < 0.05 cent  ?

is anywhere online a real config of efficient rig ?

i searched but really i didn't found

The most efficient rigs is dual EPYC 7742 (close to 100 kh/s at 600-700 watts)

but expensive

but you can try to find it second-hand, maybe someone sells it for cheap

where is proved that that is the most efficient rig

any link

Zen3 EPYCs can be slightly more efficient, but I doubt you'll find them for cheap price

someone with deeper knowledge than me must connect cryptocompare.com  with ebay prices

and the connection  is ebay prices == > how fast money will be back

3-4 years is good ROI

30% yearly is very good

3-4 years was for Ryzen 3900X or 5900X rig

it can be more for EPYC

yes but epyc is much more expensive

my epyc example was not good

maybe of power consumption

i dont know

can you give an example for epyc

how to have a ROI about this eBay-Artikelnr.:144884238920

with 0.05 cent power consumption

product price  / hash power - power consumption  == ROI
