So yes I'm looking to  sell my 350Th farm located In Quebec
I have 27 S9's all 1 year to 6 months old...I am original owner of all
(23x 13.5Th 4x14Th)
I only have access to 200amps as Que. Hydro blocked all upgrades so I can only run 24 S9's
2 dead boards...one new spare controller-board. All PSU's are APW3+ 1600W Bitmain all are working fine.
In 1 year I have replaced 3 hash boards and 2 controller boards already.
All are now out of warranty
All power and internet cables + 2x 24port switches (Dlink) 2x5 tier Steel racks which hold 3-4/tier.
I also have a 5000CFM floor fan available


Also have
2 Halong B29's with Innosilicon firmware (Decred) bought new from CK (3 months old)
2 Halong B52's with Innosilicon firmware (Siacoin) bought new from Ck (3 months old)

This is just a feeler...if interested I can provide all docs pics info etc...

Price? No idea make an offer...ALL went offline and are packed in original boxes in storage as of Sept. 19th

I am not interested in buying, but 200 Amps can easily run 120 S9s.

I’m not sure where you learned math but every S9 sucks roughly 1400-1500W which if ran on 220 V is roughly 6.5-7A.So If you have access to 200A you can only ran 26-30 of S9 miners depending on a batch

Well, if he is talking 200 AMPS, In Quebec, it normally means 200 Amps at 600 Volts. So, 200 Amps is almost 200 kW. I forgot to mention that (600 Volt) before.
So, do your math accordingly.

Wrong..
You obviously know shit about actual mining and are not speaking from experience.

Each S9 eats +1400W @ 220V that is about 6.3 Amps EACH...with line losses and in hot weather that can spike up to 6.5 EACH.
(You CAN'T feed the PSU's 600V only 110V (which would then draw 13!!! amps) or 220V)

So 30 units would draw 30 x 6.5=195Amps

I tried running 31.....guess what happened...
I've tripped and replaced my 200amp breaker twice already and even had my service entrance melt and EXPLODE and cause a fire.

28 units WAS (as in actually done & experienced for 6 months)  the max sustainable BUT was WAY OVER the 80% load rule.

Realistically, you shouldn't draw more then 160 total amps on a 200 amp service. ( 80 % rule) This avoids the very situation the OP shared. So 24 S9's puts you right at that threshold.

Anyway, I am interested in your situation. I pm'd you.

Well you never did specify the input voltage ??? kinda reminds me of this thread: https://bitcointalk.org/index.php?topic=5019507

You never specified Phases and Voltage till now. You have a small entrance of 200 AMPS, 110/220 in Quebec. I am talking about 3 phase 600 Volt 200 Amp entrance. Normally a 200 Amp entrance is 3 phase 600 volt. And we can use 120 S9s easily.

I'm afraid all bids are automatically lower for Legacy Technology Gents. Bitmain just announced their 7 nm chip tech release as pending. 3-4 X efficiency gains.

you need a young and competent electrician my friend :)

contact moi jai une offre pour toi plus interessante que vendre

Bump....
