12:18:24 <Guest89> hi
12:20:34 <Guest89> how to measure what power consumption has this server https://www.supermicro.com/en/Aplus/system/2U/2123/AS-2123BT-HTR.cfm
12:24:29 <sech1> It depends on what you run on them. PSU limits it to 2000W
12:24:51 <sech1> To measure, plug it into a watt-meter
12:24:57 <Guest89> mining with 8 cpu
12:25:04 <Guest89> i dont have it
12:25:10 <Guest89> i want to buy it
12:26:18 <sech1> Mining will probably get you close to 2000W
12:34:41 <Guest89> and what this means in terms of money if 1 hour power consumption == 5 cents
12:43:00 <Guest89> how to understand how much time i'll need for having my money back after buying that server
12:44:31 <sech1> 5 cents for what? For 1 kWh?
12:44:38 <sech1> then 2000W is 10 cents per hour
12:44:49 <Guest89> yes
12:45:57 <sech1> Check any mining calculator: https://www.cryptocompare.com/mining/calculator/xmr?HashingPower=200&HashingUnit=KH%2Fs&PowerConsumption=2000&CostPerkWh=0.05&MiningPoolFee=1
12:46:03 <sech1> I'm assuming 200 kh/s for 8 CPUs
12:48:17 <Guest89> https://xmrig.com/benchmark?cpu=AMD+EPYC+7451+24-Core+Processor
12:48:47 <Guest89> 4 * 19875 = 79500
12:49:06 <Guest89> right ?
12:49:16 <sech1> 4 CPUs or 8 CPUs?
12:49:21 <Guest89> 8 cpu
12:50:48 <sech1> https://www.cryptocompare.com/mining/calculator/xmr?HashingPower=80&HashingUnit=KH%2Fs&PowerConsumption=2000&CostPerkWh=0.05&MiningPoolFee=1
12:50:53 <sech1> you will be losing money
12:51:22 <Guest89>  why?
12:51:32 <Guest89> power consumption is too much
12:54:37 <sech1> It all depends on how much you will be spending on electricity
12:54:50 <sech1> if it's 2000W and you pay $0.05 per kWh, it will not be profitable
12:56:19 <Guest89> Thank you for your deep explanation
12:56:56 <Guest89> the last one why you said 200 khs and i found 80
12:57:09 <Guest89> you choosed other cpus?
13:06:39 <sech1> Yes, I thought it would be more powerful CPUs (Zen2 EPYCs)
13:26:44 <Guest89> Is any profitable configuration for Monero
13:27:12 <Guest89> with power consumption 0.05 cent/hourly
13:28:04 <Guest89> i don't understand how the miners keep mining if there is no profit at all
13:29:11 <Guest89> i trust Monero as the real crypto but devs must do smth about miner profits
13:35:07 <ofrnxmr[m]> Thats up to you to work on adoption
13:35:49 <ofrnxmr[m]> Miner profits are a calculation of difficulty vs marketprice. If difficuly rises with market price, you dont become more profitable
13:37:59 <ofrnxmr[m]> 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.
13:39:16 <sech1> Devs don't have to do anything about miner profits
13:39:32 <sech1> Devs care about decentralized and stable network, not miner profits
13:39:43 <sech1> Mining is a zero sum game, and only the most efficient miners win
13:43:43 <Guest89> i dont want a lot of .i want yearly 10% back
13:44:14 <Guest89> is too much?
13:47:22 <sech1> It should be more than 10% with cheap electricity and an efficient rig
13:47:41 <sech1> it should be 3-4 years ROI, last time I checked
14:18:03 <Guest89> cheap electricity  < 0.05 cent  ?
14:18:50 <Guest89> is anywhere online a real config of efficient rig ?
14:19:09 <Guest89> i searched but really i didn't found
14:21:03 <sech1> The most efficient rigs is dual EPYC 7742 (close to 100 kh/s at 600-700 watts)
14:21:21 <sech1> but expensive
14:21:33 <sech1> but you can try to find it second-hand, maybe someone sells it for cheap
14:24:28 <Guest89> where is proved that that is the most efficient rig
14:25:02 <Guest89> any link
14:26:23 <sech1> https://www.reddit.com/r/MoneroMining/comments/jx5zkw/100khs_128cores_700w/
14:26:55 <sech1> Zen3 EPYCs can be slightly more efficient, but I doubt you'll find them for cheap price
14:29:08 <Guest89> someone with deeper knowledge than me must connect https://www.cryptocompare.com  with ebay prices
14:30:07 <Guest89> and the connection  is ebay prices == > how fast money will be back
14:30:22 <Guest89> 3-4 years is good ROI
14:30:49 <Guest89> 30% yearly is very good
14:32:15 <sech1> 3-4 years was for Ryzen 3900X or 5900X rig
14:32:19 <sech1> it can be more for EPYC
14:35:12 <Guest89> yes but epyc is much more expensive
14:35:43 <Guest89> my epyc example was not good
14:35:55 <Guest89> maybe of power consumption
14:35:58 <Guest89> i dont know
14:46:55 <Guest89> can you give an example for epyc
15:04:34 <Guest89> how to have a ROI about this eBay-Artikelnr.:144884238920
15:04:51 <Guest89> with 0.05 cent power consumption
15:18:07 <Guest89> product price  / hash power - power consumption  == ROI
