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.

its only minus 7 years warranty , but all the specs are the same . and 50 euro lesser , anyway tnx for your input , i think i am going to try this 1 out , since i have to wait on my money of the RMA that i have to send to the store tommorow !

Exactly ! 1000 watt seems more logical or 850w I dont want to RMA a second PSU Tongue

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 ! ; Wink

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.

wooow those EVGA's are quit expensive , VGA SuperNOVA 850 G2 @ 150 euro's and the corsair cs850m starts @ 126 euro EVGA SuperNOVA 850 B2 @ 125euro @ ,

Yeah, but when i say they're good psu, they're GREAT psu. You can't compare a EVGA g2 850w to a whatever 850 watts. The EVGA g2 850 will run 940watts at the wall 24/7 with great efficiency and clean power. And 10 years warranty so any talk of PSU degradation that are moot from the start become completely irrelevant.

and what are your thought on this 1 ? http://www.lc-power.com/en/product/netzteile/metatron-series/lc8850iii-v23-arkangel/ ?

Power rating 850W
+3,3V 25A
+5V 25A
max. combined 130W
+12V 70,8A
max. combined 849,6W
Efficiency up to 92,5%
Standby consumption 0,4W - ErP 2013

and only @ 99 euro's it is not that i dont want to pay Cheesy

Exactly ! 1000 watt seems more logical or 850w I dont want to RMA a second PSU Tongue

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 ! ; Wink

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

If you go for a cheap PSU, you're going to get poor result, as simple as that.

The EVGA is well EVGA, G2 is a serie GS is a silent serie, there is no difference for a miner. Search in your favored electronic retailer either EVGA G2 or EVGA GS. Anything 750w+ will do for overclocking both unit. 650w will do if you do it the reasonable way. Anything higher than 750w if you plan on upgrading, depending on how you plan to go about it.

Its a bit more expensive than going for a decent corsair or a good seasonic, but i get to push my miners higher with these. And 10 years warranty.

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

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.

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.

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.

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.

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

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

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

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.

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 . Cheesy

Definitely will try that when i got enough room ! Grin

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.

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 Sad

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