Topic: U.S 110v PSU for Antminer S9 suggestions please (Read 709 times)
it will cost you a few dollars at most to install a 20a 230v outlet. check your local codes but you literally only need a 20a breaker or {30a &10ga}, 12ga wire and the outlet. it took me maybe an hour to install one in my home. if you're tech savvy enough to run an s9 installing a breaker is even easier. make sure to do it during the day as you have to kill the main breaker to do it and won't have any artificial light. a $10 book will hold your hand through the whole process
Correct me if I’m wrong but if you are running the appropriate gauge wiring on 30amp breakers you can easily run an s9 on 110v.
Most residential circuits in the US use wiring and breakers sized for 15 amps INTERMITTANT service at 117 VAC.
Some "kitchen" outlets, and most A/C outlets are sized for 20 amps at 117 VAC but those are not all that common outside of kitchens.
When operating equipment 24/7 the NEC requires you to derate the circuit by 20% - so that "15 amp" circuit in CONTINUOUS USE like with a miner becomes a 12 amp circuit for safety reasons.
30 amp wiring at 117 VAC pretty much doesn't exist in the US - higher power appliances and equipment is designed to use 208v (industrial split out from a 3 phase circuit) or 234 v (standard "use both hots on a standard split-phase residential or SMALL business feed) instead.
Yes, IN THEORY you could have a 30 amp 117 VAC feed wired up and run an S9 from it - but in practice, if you're going to have such a RARE feed setup installed (and good luck finding OUTLETS for it, anything over 20 amps in the US is specifically intended for use on 234 V - there is no such thing as a NEMA 5 outlet at higher than 20 amps) you'd be better off just having a STANDARD 234V circuit and outlet(s) installed instead.
I would use two APW3++ power supplies off of 110. Decent quality computer power supplies are getting WAY too expensive these days and a cheap off brand one would probably have less resale value than an APW3++.
I have had good experiences running Avalon miners on 110v from an APW3++. Other people have ran S9s on 110v using a single APW3++, but internal components are likely being stressed beyond their engineering. I wouldn't recommend doing that.
If you want to buy computer supplies in the US...you can sometimes find them cheaper from Amazon.de or .co.uk AFTER shipping to the US than in the US!

It only costs about $180 dollars to install a 30 amp circuit in you home. You can then run 4-5 s9’s off of that.
Is it really that cheap to run a 30 amp circuit? What about rewiring for the outlet?
Honestly it's hard to estimate a price for all environments and areas of the country. But I would imagine if all that needed to be done was run some wire and an outlet then yeah it wouldn't be too much. **But** everyone's house/building/shed is different so just use it as a very rough guide.

I know this has been asked and trust me I've googled. Most things I've scene googling are sold. I'm looking if someone could point me directly to something in stock that will power the S9 on a standard U.S outlet safely under $400
I've scene the EVGA 1600W PSU but they are $450 and people have had problems.
I've scene a couple kits that use 2 server PSU's but would prefer to stick to 1.
I see a lot of server psu's on ebay that claim to run but I'm not technically knowledge enough to know what the cheap and scam ones are. They all claim high efficiency.

why not run 2 of these

use one on blades 1 and 2
use second on blade 3 and the controller
even better/cheaper you could use this.

OMG!
Please notice that Parallerminer.com has wrong instructions for their HP server power supply kit, which will most likely end up creating a hardware failure situation, in which the two different power supplies kill each other.
Never connect two power supplies into same hash board. They'll 'fight' each other to death.
With 110V mains voltage, two power supplies setup and Antminer S9, I would definitely use one HP DPS-1200 FB A and one HP DPS-750RB A
for the power supply setup. DPS-1200 connected to two hash boards and DPS-750 connected to one hash board and control board.
See instructions in the image above (the one with green text).

I’ve had experience with the EVGA 1600 P2 running an antminer on a 20A circuit for months nonstop and have had no issues thus far. The 15A circuit wasn’t enough to support it.

^^^ This FTW, again! Phil knows what he's talking about.

This is the standard in USA per NEC code for residential wiring. Yes, a 30A breaker with 10 Awg wire can handle (2) S9s on 110v service. A 20A breaker with 12 Awg wire can only handle (1) S9 on 110v. The wire is usually rated for 75F. Most 110v outlets in the USA are rated for 15A and 125v and are usually connected to a 15A breaker with 14 Awg wire though some maybe wired with 12 Awg wire depending on the circumstances who did the wiring. It's not recommended to run an S9 on these 110v residential outlets in the USA as the "continuous" current draw of an S9 running 24/7 exceeds the rating set on a standard 15A breaker and wiring. This is also based on an ambient temperature rating of 86F. If the ambient temperature exceeds 86F, then the ampacity of the wires need to be adjusted accordingly.
Correct me if I’m wrong but if you are running the appropriate gauge wiring on 30amp breakers you can easily run an s9 on 110v.
...I'll think about running 2 separate 110V PSU's
This FTW. This is what I don't get either. I don't understand why people are not using the Bitmain APW3+++ power supplies. Yes you will be hashing a little less (in my case most of 13.5ths batches are hashing around 12.4-12.7 with extremely low hardware errors).
The answer is real simple. The APW3 puts only 1200w out when running on 110v. While your s9 may be running on that you are pushing the power supply dangerously hard and it will fail, if you are unlucky it will take out some of your s9 hardware with it. So dont be dumb and burn up your hardware because you dont understand how electricity and power supplies work.
If you can get one, the APW5++ will run an S9 on 110V well within the 80% max recommendation. As an added advantage the APW5++ has a large and very quiet cooling fan.
You also need to consider not just the wiring, but the junctions. Solid wire can handle a lot more power than a bad junction. And since outlets are daisy-chained where power to the final outlet on the loop goes through every outlet inbetween, there's a lot of potential failure points. If you have to use 110V outlets on 14AWG wire, please use the first one in the chain.

As long as you are not running anything else on that 110v circuit and use proper 14awg cables for the power supply you should not run into problems. I am not an electrician but I do understand that the 14awg wiring on a 15 amp 110v circuit is rated for close to 70 degrees Celsius. I have touched the wires running by my panel and although they are very slightly warm, I have never tripped a breaker. At 100% load a 110v 15amp circuit will be able to push out 1650watts. You're going to be closer to 1400 and although you are not at the recommended 80% maximum for continuous use I am sure you are fine (this is just my opinion).

Can’t you just run the apw3++ psu from Bitmain on 110v?
Server PSUs will only output enough wattage if they are on 220. 110v gives them decreased funtionality.
If you are thinking of throwing that much money away on a PSU you may as well just pay to have a 220v breaker/socket setup. Then you only need to spend $100 for a PSU strong enough to run an S9.

(2) HP 1200w power supplies will put out enough wattage to power the S9. They run off 110v and you would need the (2) breakout boards for the PCIe cables.
