Hello

I am new here. I need to hear some opinions.

I have offer to buy this mining rig:

GPU: 6x Sapphire Radeon NITRO+ RX 470, 4GB GDDR5
PSU: Seasonic Prime SSR-1200PD
MB: ASROCK H81 PRO BTC R2.0
RAM: Crucial 8GB DDR3 1600MHz CL9
CPU: CELERON G1840 2,8 GHz 1150 DDR3
SSD: Kingston SSDNow V300 120GB 7mm
PCIe: Qumox PCI-E 1x to 16x Powered USB 3.0 Extender Riser Card BTC Mining


Everything is already set up. Just change wallet and mine.
everything is still in warranty 21 months left

Seller was mining Ethereum. His hashrate was

 ETH 166MH/s (OC) a 144MH/s (default) / 850W

price is 2500€

What do you think? Is it profitable?

Probably I would not pay for electricity. But I would like to know your opinion if it is profitable even if i paid electricity.

Thank you

David

I would not purchase it for 2500 Euros, that's for sure.

Price is way too high, a rig like that I would pay only around $1,700 USD. This price is what those components would normally cost new, but with the markup on everything because of miner demand your friend is probably not trying to cheat you but only recover his costs since he paid about a 150% premium for everything.

At the asking price you would be hard pressed to ROI on it anytime soon.

You do not state your electrical price (cost per KWh), but assuming it is around $0.10 USD you would only earn around $6 USD a day with that rig. I am not sure what the exact conversion rate is to USD, but assuming the rig is somewhere around $2800 USD, you would be looking at mining 466 day's just to break even.

If you get free electric, you would earn ~$7.50 per day and ROI would be roughly 373 days. Keep in mind the actual payback period will likely be much longer as network difficulty continues to climb. So even if ETH's prices goes up the increasing difficulty means you will mine less and less coins as time goes on.

IMHO, it is NOT a good investment.

This rig costs too much! ~2000$ is reasonable.

here in the USA you can build that rig from around 2000 USD
2500 euro is almost 3000$ with today exchange rate .

I would say its to expensive to pay 3000$ for 144MH/s rig , even if its overclocked can do 166MH/s


to answer to your question , we need to know how much you have to pay for the electricity kwh/USD or kwh/Euro

That is correct electricity rate is the main concern here and i think OP can provide huge amount of money to buy much better rigs for his mining, just consider the amount that you pay in your electricity and calculate if how many weeks or months could get the ROI.
We all know that OP question was already answered but this is only other tips to him.

Hello

Thank you very much for your answers.

Sorry I forgot to add electricity price. My electricity price is 0.05€/khw roughly 0.07 USD

Thank you, you helped me a lot. So If I push price down below 2000€ it is reasonable to buy, otherwise its not so profitable.

Even if I pushed price below 2k woud it be good deal?
For mining ethereum or other currencies?

I wanted to jump in mining, but probably this is not right rig to start.

this might be better option for you:
PANDAMINER (https://www.pandaminer.com/)

There is two version available :

Meh. OP make your own for best bang for the buck solution.
Others are all going to take a cut IMO. If its an ASIC I can understand but if its just a GPU rig then anyone should be able to make it.

That Panda miner website is just stupid (apart from the obvious grammatical errors). I'd like to steer away from Chinese companies as much as possible.

Better to make it yourself that way you learn to troubleshoot as you go along.

Most of the ASIC hardware made in china :)
If you can understand what the panda miner is , then you should know its not ASIC hardware :)
(For this information of course you need to DO a little bit more than just SEE those links, YOU MIGHT NEED TO CLICK ON IT AND READ A LITTLE BIT ) ;D

OP want to buy not to build :)

Looks like you find a lot of " grammatical errors " on they website , that is why you was not able to get a basic information about those miners ( asic or gpu ) ;D

 ;D I DON'T UNDERSTAND WHY SOMEONE TRY TO GIVE ADVICE FOR ANOTHER MEMBERS , WHEN SHE/HE HAVE NO IDEA WHAT SHE/HE IS TALKING ABOUT  ;D
