DUAL S9 MINERS - How do i mod the PSU?

[xioxian]

Hey guys been a while.

Just relocated and im looking to make all my old S9s more efficient by doubling them up as i have 4.

I understand the control board process , resistors etc but i dont understand how i power the extra 3 hash boards?

Do i just simply add more plugs to the PSU?

TIA Guys.

waste of time.

the psu can do 1600 watts no more.

you cant run six boards at full speed the psu will burn out.

is your power free?

the best you can do with an s9 is 13 th at 1000 watts. ballpark numbe using braiins.

you have four of them this means at best 52th at 4000 watts.

if you pick up an s17pro it can do 42th at 1400 watts.

If you are usa based i have s17pros run three at low speed you burn 4200 watts and get 126th

in either case free power helps and you can run them.

but the s9 improvement you want to do is wasting your time.

My S9 best W/TH is at 800w.

Hey yes i do have free electric, Thats the only reason why im still willing to use these meanwhile. Understood ill do that then its just that one needed a new control board and i do have a 1800w bitmain PSU?

My S9 best W/TH is at 800w.

are you burning 80 watts a th?

or 800 watts a miner.

@op



I get that free power and not laying money seems good.


but running 52th vs 126th and burning 4000 free watts vs 4200 free watts

is 74 x 8 cents or just about six dollars a day more running s17pros on low

that means 1080 usd extran in six months of s17 pro
and 2160 usd extra in one year of s17 pro on low.

are you usa based or asia based. you can get s17 pros for cheap. i would upgrade

S9 800W on miner 75W/TH
I have S17pro, best performance at 1500W on miner, 38W/TH

S9 have very high W/TH even for free electric, I suggest S17 or newer miner.

I will be brutally honest as i have no shame, I have been crypto obessesed since 2021 and i have started from literally being homeless, I began GPU mining, Built them, Sold them.

Switched to ASICS, Bought 4 S9s, and a T3+ Innosilicon all used for dirt cheap, Carried out all the repairs etc myself so i have been learning with first machines but i have learned alot.

Now i have relocated and finally in my own house with free electric abroad, and multiple properties courtesy of my landlord and our new partnership.

So yeah - My next purchases was maybe going to be the Ipollos i think? 80TH for 550 EUROS?
