Recommended PSUs for 120V S9?

[IanWorthington]

Is there a FAQ anywhere for recommended PSUs for an S9 running on 120V?

I've found a couple of (expensive) 1600W PSUs on newegg/amazon, and used IBM DPS 2000W on ebay.  Anything else?

You might also want to consider a solution with two or possibly three power supplies. I know that Parallel Miner used to have a kit with a 1200W and 750W power supply combination. See: https://www.parallelminer.com/

Three 750W supplies would also work.

No matter what, you obviously need to make sure you have adequate 120V wiring for this, with a dedicated 20 Amp circuit with a couple of outlets. If you go the multiple supply route, you do have to turn things on and off in the right sequence.

I also like 3x DPS750.  You can find them for <$20, but you do need to get breakout boards as well

 For the expense of the 120v power supply just wire up a 240v breaker and put in a Nema6 receptacle. You can get the APW++ For $200 all day on ebay or amazon. It will aslo save you 6 amps.

I've only got a dedicated 120V/60A/8kW circuit here so need to make do with that.  If I ever need more than 8kW/60A I'll get them to quote for 240V as well.

Why a 20A circuit?  The S9 14TH/s model is rated at just under 1400W at the wall, ie about 12A.  I was going to wire each into its own 15A breaker with 8 AWG. With either an individual or group RCCB/RCD.

I'm very nervous about the multi PSU idea, seems a PSU failure could kill the S9?

Parallel Miner looks interesting, thanks!  Seem to open up a whole new bunch of PSUs to use.

240V cuts your amps in half. I'm running 2 S9s with their own single Apw3 on a 20amp 240v breaker with two Nema5 6 receptacles.

Edit- if you have a dedicated 120v circuit, you can very easily make it 240v. The reason it's 20amp is because that was the lowest amp 240 Breaker I saw at the store and I planned on putting 2 on it anyway. Unless it's in your wheelhouse, you might want to have an electrician make sure you have the space in your panel for the double breaker.

Not here I can't: Only single 120V to the property.

Fair enuf!

I still think itd be worth calling an electrician for a consult. 120v is a single breaker with a single hot and common. 240v is 2 hots on a double breaker.  If you have a clothes dryer, it runs on 240v, like your HVAC as well. Its all done at your panel.
