So, I'm the only one with power in my area right now. A bunch of local businesses, like hardware stores, are connected to my supply and cover the electricity costs in exchange for the hookup.
I'm looking to set up my own mining rig that can actually turn a profit without burning too much power. Ideally, I want something that won’t exceed 1000 kWh per month but still gives a good return. Money isn’t an issue for the setup since I’m ready to invest.
Best mining rig recommendations for my situation

1000kwh in a month they are 1500w per hour of consumption, 1,5x24x30 approximately 1000, on that power there are some asic but a little dated, in a month you would not return to any investment.
With this option, I would buy a RX 570 or RX 580 4 GB. These video cards can be found inexpensively in very good condition and very cheap, about $ 700, to make a mining farm for ethereum forks with a hashrate of 240 megahash - 8 video cards. But only sell coins in the next bull market.
with that amount he can also buy 2 L3, I think they are more profitable today.

If you only have 1000kwh per month for Bitcoin mining you can only use S9 miner that consumed around 1400w per hour and around 1000kw in a month.
Or if you are looking for Bitcoin miner that doesn't consumed much power check USb miner like Compac F 48 pieces of them can hash around 14.4th/s with very low power consumption.
Unfortunately, today it is very difficult to find an Antminer S9 in good condition, because it has been on sale since mid-2016. Or buy several ASICs for block repairs. But asics make a lot of noise, which will be a bad solution for mining in the house, and mining a farm from video cards does not make much noise.
Is the ROI will still be slow if the cost of electricity will be excluded on the computation. Im trying to purchase a miner that doesnt have any complex method to build. I can extend to 2000kwh for a month but with less noise as much as possible so that my neighbor beside my farming house will not be distracted.
Whats the estimated time of ROI on your suggested rig?
I preferred Bitcoin because I already loss confidence on Ethereum after the merge. Mining fork coins is gamble for me. I need to ensure the ROI first for my rig cost before I can venture on risky altcoins mining.
Thank you. I will try to check some of this rig price and specs.

Hi bro if you want best of best Bitcoin mining Rig than Bitmain antminer S19 pro that is the best if best and it offers 110 TH mining power and that can generate almost 6 to 7 dollars per day that is a good start and can be a best passive income. And there are many other coins that can also generate good profit too. Here is a screenshot of mining profitability.
That 6 dollars can be misleading since you need to factor in the cost to mine, not to mention it needs 3kw electricity which is probably out of OP range. Instead of making a profit, he might suffer more loss if he buys it (unless he mines indefinitely). CMIIW.
s9s are very loud. The L3+ much much less.

I disagree the L3+ burns 750 watts
2 of them do 1500 watts.
2 of them earn about 3 usd a day
90 usd a month
they merge mine ltc and doge
also a s17 pro set on low will do 1200 watts which is 1.2 x 24 x 30 = 864 kwatts
it will do 40th which is 40 x .063 = 2.52 usd a day or $75.20 usd a month
the key is what does he pay for his power

You can buy a s19 and undervolt it with aftermarket firmware to use around 1300 watts to stay under your monthly 1000 kwh target. You will probably get 50Th or so on a s19 with that undervolting.
If I understand the author's post correctly, then 1500w per hour is free. 2 asics for litecoin will give about 100 dollars of profit per month, but he will have to deal with noise. This is not such a large amount of profit now, but if you do not sell coins, then perhaps there will be more profit.
Your monthly Maximum power consumption= 1000 KWH
For A day Power Consumption= 33.33 KWH=33333WH
For An hour power consumption= 1389 W
Above mentioned situation below mining rigs suitable for yourself..
Bitmain Antminer S9
Power consumption 1323 per Hour
Bitmain Antminer S19 XP
Power 3010W per Hour
MicroBT M50S
Power 3276W per Hour
Bitmain L3+
Power 790-800 W per Hour
Device choose your own risk.

the L3+ with proper firmware uses 680 watts.
fans can set to 50% even lower.
and if you use a 1000 watt corsair gold vs antminer apw psu it is quiet.
Most ASICs are loud, I have not seen ASICs for installation in an apartment for a long time.
The problem of noise is well solved by installing soundproof boxes for ASICs. The author wants maximum profit, so buying several soundproof boxes will not be expensive.
I have 2 l3+, set with hiveos at 504mh/s they absorb 660w, at the socket they will be 10% more or so.
Fans with ambient temperatures between 15 and 20 degrees c are always between 30 and 50%, rarely more.
