Hey everyone I want to set up an Antminer S9 using just one or two cards, and I'm hoping to lower the fan speeds. I'm trying to find a quiet ATX power supply instead of those noisy 1600/1800w server PSUs with their loud fans. I've been looking around and I have a 750w ATX PSU, but it only has one 6 pin PCIe connector plus a bunch of those 5v/12v SATA connectors, I think. Is there an ATX PC PSU out there with 4 or even 7 PCIe connectors? I’ll start using one card first, so 4 would be enough for me (1 for the control board and 3 for the hash board). Does anyone have any suggestions and what wattage would I need for running 1 or 2 cards along with the fans and controller? Thanks!

the corsair 1000 rm will work https://www.newegg.com/corsair-rmx-series-rm1000x-cp-9020201-na-1000w/p/N82E16817139273? I suggest you program the unit with braiins. and set watts to 1100 thus you will use. ⅔ of 1100 = 720 watts it will work

Thanks, i presume BRAINS is software for the S9, i use Slushpool and have never used it tbh.... Another question which i think i need to start a new thread on is what is the best position for the boards when you have bank 6, 7 and 8. I find ALL my S9's fail on board/bank 8 (furthest away from pcie connection on control board). I also don't think placing them in banks 6 and 8 with a missing board in the middle would be better?? Anyone checked this, i have searched but no answers. Thanks for advice, much appreciated.

The center boards get the least air so they should fail more..  I have found they all pretty much fail any way they want to.  But I only had about 50 s9's with under 10 bad boards.

Thanks, i am juts setting up an S9 with a single board that is in the centre slot and i'm using a generic CPU to pwer it. It runs at 3.4Th at most. Is it worth me installing Brains OS and reducing the voltage/power? Also shoul i install Brains software on all my other S9s as i only use Slushpool because it has a great UI. Thanks

The purpose here is only for noise reduction. Power usage is not a concern. Just noise. So basically looking for one card set up using an ATX supply. Anyone done this, the main misuse are going to be the miner fans now I presume. Brains software and want to set it at? Any mods to make physically like adding a inlet/outlet muffler or are they snake oil? Using ducting is not an option. Thanks again
