Looking for a PSU for : Antminer S1 and S3

[ganjasmokingg]

Hello good people !  

I have been mining for some time but only with GPU's and CPU's and i buyed some miners for fun , and now i am wondering if it is possible to power my Antminer S1 and S3 on 1 PSU ? I know it is possible but i am not so familliair with many PSU's  but i do know now that many people recommend a single 12v rail . around 500+ watt 12 v for 1   and   for 2 miners i really have no clue   

And now here is the question !

Can someone please recommend me a proper PSU wich can do the job , and please no Corsair unless it is  good one with proper parts , not like the VS550 or something , i have bought an VS550 already (had to RMA it ) , i tried the paperclip test and not even with the miner connected the PSU was already failing  the (VS550) i tried it also with some fans connected to the PSU but that was also not working .
I am looking for a PSU that can power both miners S1 + S3 without any added fans or old HD or ....
 ow yeah keep in mind that i did not connected any miners to the PSU and it was already DOA

I really want to mine soon ,

i  hope someone can help me out with this  !


    I thank you all dearly !

I use a Corsair RM1000x for two S3+ no problems at all.

[whizz94]

The second-hand 750W Corsair sold with two second hand S1's could just about run both of them but could cut out when both fans went fast and was insufficient for overclocking.  I now use it on one of them.

Two scrap 'ordinary' ATX "500W" supplies which have >16A rating on the 12V line can be used to power each half of an S1.
Try looking at the specs of the S3.  You might find that each half draws about 22A at 11.6V and you might find that you have scrap ATX units which can supply that.  Trouble is you'd need four of them, and cheapest "500W" new ATX mostly won't do that much on a single 12V rail.  All of these have the usual "paperclip" from green to black on the 24 pin connector, and that has been good for months.

I think that you need about 400W for the S1 (360W with margins) plus about 500W for the S3 so to get that in 12V from a single power supply instead of four ordinary scrap ones you'd be into the premium range of 1kW and greater power supplies.  I don't advise because they all look pricey, but you might want a look at the 1600W supply from bitmain.

  tnx , i was already thinking about that ,  but i see some people also getting it to work with around 850watt but i will keep this psu in mind !

i run a dell server powersupply that i got from sidehack a member on here it runs 4 of my antminer s1's 3 that are underclocked and 1 thats stock clock

its a 750 watt psu and there fairly cheap

I wish i could buy some scrap PSU 's over here  but all the PSU's are too far from my place , its better to buy online . Maybe after a couple of months when i buy another miner i will look to get that 1600w supply from bitmain , right now i am a bit low on funds to pay like 200 euro  + the tax costs  

For now it is better for me to just buy something for these 2 miners , but thanks for your suggestions !!

i run a dell server powersupply that i got from sidehack a member on here it runs 4 of my antminer s1's 3 that are underclocked and 1 thats stock clock

its a 750 watt psu and there fairly cheap

Wooow 4 ants on just 750 watts ,  sounds like a nice project for me ,  for some other time ,anyway  thanks for sharing .    
Definitely will try that when i got enough room !

Be cautious with underclocking claims.
I've not had an S3 to test.

My S1 could underclock from stock 350 MHz to 300 and 250 MHz, which decreased power consumption and hashrate commensurately.
I ended up overclocking to 381 and 392 MHz in summer and dropping back to 350 or 325 MHz in winter when there is less free electricity here.

Whilst you probably could run both of your units underclocked, you might not want the decreased hashrate which goes with that.

[cavaliersrus]

you can ask sidehack about them he did underclock / undervolt on 3 of the units i bought from him and i consulted with him about the powersupply before up and running it making sure they would be fine on 250 freq

To safe you money buy a CORSAIR 750CSM PSU.
I have 10 x Corsair CSM 750 @ 2x Antminer S3's setup.

Never had a problem. For your S1 and S3, it should work great. And if you decide to buy another S3 one day, you don't have to buy another PSU.

Is there a big red "bulllshiessen" button on the webpage for me to press?  Preferably which sets off flashing red hazard lights and honks a comically loud klaxon.

An S3 and an S1 on a 750W 12V rail would have to be so underclocked that you'd rather not do that.
Look up the power specs of the model and series number of your miners.  While you are there, look up what one series-8 S7 would use, since planning ahead can sometimes be a good thing. 
To, for example 360W for your S1 add a bit for overclocking headroom plus current surge when fan speed is increased.  eg 420W.
Do the same for your S3.
add the two numbers together.
It won't be inside 750W, and that ATX trips a shutdown at exactly 750W, even if you go a little bit over for much less than a second.

Yo   i dont plan to underclock ! I really want the full hash rate !   tnx

seems a bit risky to me , since i am not planning to underclock , but anyway tnx !

What are you talking about? An undervolted S1 run easily 140GH/s at 160Watts. Then add 355watts for the S3 at stock speed. Thats a total of 515watts. I don't see how 515watts is greater than 750 watts.

Then 2 S3 is 710 watts. So the post you replied to was absolutely right. And you were absolutely wrong.

Exactly ! 1000 watt seems more logical or 850w I dont want to RMA a second PSU  and also  no underclocking for me , maybe about 2 months later i will buy a 1600 watt bitmain PSU , but for now i need something cheap nothing special.   and tnx for the suggestions !    ;

I don't know why you would want a 1000 watt PSU for a 470watt load. Unless you're in the business of running the S1 at 200GH/400Watts, at which point something like a EVGA G2/GS 650/750/850/1000/1050 are all valid options. Depend simply how you intend on expanding later on.

But this is when you underclock all the miners right ?  Really its hard to believe it will work and i also want a bit of room to OC both !

A S3 is 355watts at stock speed, 450 or so GH/s. You don't underclock it at all. You can try to overclock the S3 but it won't go much higher and it wont take much more power either.

You can overclock your S1 as well if you want, which is pretty much a waste, but you can. I dont see the point of consuming an extra 240Watts for 40GH/s, but thats up to you, not me.

Which is where any of the EVGA i recommended comes into play, they all would work.

Yooo I will definitely compare some of those EVGA's ! or this 1 ?  http://www.lc-power.com/en/product/netzteile/metatron-series/lc8850iii-v23-arkangel/ this will also do right ?    for my next miners i will just go for a  bitmain 1600 watt , or some other PSU from the miner store , i always forget that the seller also have good PSU's in the 50 euro range !  But this time i will write it down somewhere so i wont forget it the next time when i am planning to expand! .

anyway tnx for your suggestions

REally can somebody please confirm this ? ?  i am also happy with stock speeds , but not so happy with underclocking and losing hash !
If this is really the case than i will purchase an 80 PSU gold 750watt+   single rail or double 12v rail ?   tnx
