s1's were great reliable miners , im still partial to the 12 s2's i still have running to this day they have been on 24/7/365 for a long long time , only reapirs on them have been regular cleaning and a few psu fans have needed replaced
that being said all my s1/s2/s3 miners have been the most trouble free miners i have ever had , seems like quality started to take a turn at the s4

lol after posting that picture and replying about the s4 in the picture the darn psu died or should i say exploded , lol surprised it took this long as it was one of the original batches with known psus issues
You sure you still want to run the S2? Specifications Antminer S2:
Hashrate: 1,000GH/s (1 TH/S) Power consumption: less than 1,100W from the wall
those are s4's and they still turn a profit for me , i have .6 MW of power available so its not like im hurting for power for the s7/s9's
thats almost 1400 watt for 2 terrahash, you have free energy?
not free but very very cheap , the more i use the cheaper it gets as well
Where are you located? You are very lucky with your electricity prices I wish I had those prices then I could mine too
You should consider hosting other peoples miners so you can get even cheaper electric.
utah, usa . i do host for some ppl mostly ppl ive made friends with from various mining pools.i just dont advertise it, but if anyone needs some small scale hosting i can do it( i.e 1-4 machines etc ) i have no interest in hosting large mining operations i.e 50-100 machines etc

finally decided to clean up my mess this is an old picture but the new hardware was just as messy
and so far ive goten it to this lot more machines to do before the end of the night
Oh, sad too see that Did the voltage go way up in that situation? Presumably yes.
yes input voltage spiked between 350v to 480v at the psu luckily i was able to salvage some of the boards and put together 1 and 2/3rd's of miners out of the 4 that got hit i run 3phase 480 that i split single phases into 277v power , so the system has to stay balanced on all 3 phases
ouch.. im hurting just looking at it. what power supply are you using? doesn't it have any over voltage protection?
i run a mix of 2880's dell 750's dl580's and a few others like dps 800gba and dps1200's
one of the 2880's actually arced across the input terminals , and the other was fine go figure

the things u do to keep ur machines running , heres a video of me leaving my data center today , luckily there was a break in the snow storm https://www.youtube.com/watch?v=w1sRX_YRW-Q
normally id just drive my car but wet/icy/snowy roads + a turbochared camaro dont mix so i hopped on the dirtbike instead, luckily my datacenter is nly a 14 mile roundtrip from my house

Are you alright with taking the large financial loss of running those miners?
they were on free power, and even the power at my datacenter is super cheap , that being said i finally took down my s2's a few days ago and replaced them with under clocked sp20's , the sp20's came out of my datacenter so i figured i would replace the s2's with them so i can dbl the hashrate at the free power location
as much as i hated to do it ive been stripping down the s2's and parting them out , psus , fans , beagle bones etc , i might hold onto a case or 2 just to see if i can repurpose them for anything , been thinking about seeing if i can stuff them full of s7//s9 blades with an ibm 2880 psu to make a nice rack mount case. but thats not real high up on the last of things to do

ECS Lending This is a very interesting concept for passive investors and extremely suitable with those who are looking for investment opportunities without calculating profit collected from their investment.
ECS Trading This option is also rather potential for investors although the profit margin is not equal to lending. But with a stable development trend, this is still a profitable investment opportunity.
ECS Staking If you are a person who is really busy, consider this option. It will bring you considerable profit from hoarding ETHBlockNet (ECS). ECS Mining This is the final way out of the above methods to be able to earn profit by mining. We provide POW algorithms so people can mine with the amount of coin we permit.
