"As It Is" Antminer S9 From D-Central d-central.tech/product/antminer-s9-as-is/

I've been looking a bit more into home mining. I think aiming for around 10TH/s and running costs of under 1000 watts seems like a sweet spot. I came across this option from D-Central where they have old S9's that haven't been checked selling for $30-35. That basically means that some might be working, some won't. The price is about half of one that has been inspected.

Are they easy to fix? I was thinking about getting a bunch and using some parts of the duds to keep for when the working ones break.

Do you think its a bad idea to try and fix this stuff yourself?

I have one but I sprang on the whole space-heater setup.

FYI, their optional vonnets wifi adapter was not compatible with my router (something to look out for), and even this small fuss had me pulling my hair out for two days before I surrendered. If you're patient and willing to learn, then go 'as is' - but best to go in with a hobbiest mindset and not for huge gains.

Honestly, I think the s9 is a decent buy, even for the refurbished one. I learned a lot and this winter I mined upwards of 23k sats.

Keep in mind that they are old machines so they might get bonked-out for one reason or another and need a repair. Also, the fans might drive you crazy of its in your house. Mine makes a ringing sound that carries through the wall into the next room, even with the modified 'quieter' fans.

Good luck!

Thanks for sharing!

The noise is one thing I'll have to deal with if I go through with getting an S9. I remember seeing some sound proof boxes a while back. I'll definitely need something like that, probably aim to make it myself.

Very cool. You could get two new nano 3s, which would give you 12TH/s for 280 watts, but that would set you back like $800

That's right.

I mean, the big difference besides the price is the noise. These things really are built for industrial use.

If they offer one for double the price that you listed, and it does work, I’d choose that personally. Fixing it after it breaks usually means one thing broke, but if you get one in an unknown state, who knows how much is wrong with it. Just my 2 sats

Edit: buying these for spare parts seems like a reasonable choice given you want to work on them

Might be worth getting at least one that works, and then try my luck with some of these "as is" ones.

That sounds like a good idea

I saw this and got all excited. Then I checked it out and noticed it doesn’t include the power supply. The power supply it needs isn’t just like and AC/DC converter. You really need to pick up one specific or custom modded to the s9, and those tend to be just as much. Not trying to discourage. You seem to be just the kind of dude we need helping to secure the network. Just hope you’ve got your eyes open about the power supply situation.

I was wondering about that. If the power supply is just for the US or if you need one for other parts of the world.

I'll have to look into that more.

Thanks

Nice, I’ve been considering this too. The ‘as-is’ S9s could be a good risk/reward situation, especially if you’ve got the time and patience to play around with them. If you’re handy with repairs, it could work out.

I wouldn’t go all-in on these though; maybe just pick up a couple to experiment with, and then see how many of them you can get running.

The idea of using the duds for spare parts isn’t a bad call, but just be aware that it might take a bit more effort than expected to get them up and running, especially if multiple components are shot. Could be worth it in the long run if you're okay with a bit of a project!
