Anyone running two or three oc ant of one psu? If so which ones?

Also do ants need modular or non modular type which is best?

thanks

I suggest one 800W bronze plus per OC ant...gets the best efficiency. Efficiency will be important when connecting more than one ant to the same breaker.

This configuration should allow you to safely connect 3 ants to one 15A breaker.

I was thinking this...Corsair CX Series 600 Watt ATX/EPS Modular 80 PLUS Bronze ATX12V/EPS12V 552 Power Supply CX600M

http://www.amazon.com/Corsair-Series-Modular-Bronze-CX600M/dp/B00ALYOPSS/ref=sr_1_fkmr0_2?ie=UTF8&qid=1394295808&sr=8-2-fkmr0&keywords=Corsair+CX+Series+600+Watt+ATX%2FEPS+Modular+80+PLUS+Bronze+ATX12V%2FEPS12V+552+Power+Supply+CX600MCorsair+CX+Series+600+Watt+ATX%2FEPS+Modular+80+PLUS+Bronze+ATX12V%2FEPS12V+552+Power+Supply+CX600M

Is this sufficient for one Antminer S1 ?
will I need anything else beside the jumper (can I strip a copper ground wire and leave some shielding on, or is there a better way?)
Any other advice?

Thank you :-)

It really is that simple... Paper clip from green to black cable next to the green one. You can also just google "power on psu without motherboard".

I would suggest you use decent sized "wire" and just cover with electrical tape to ensure safety. Copper ground wire might actually be too big depending on the AWG, but try it. I would say it should have some resistance to put in and take out but doesn't make your face red while doing it:)

I couldn't find a paper clip so I found one of those small black paper binder clips, took off one of the "levers" and bent the ends straight... it was some work but they fit and won't be going anywhere lol...

CX600 is fine, it's got 40A on 12V rail. More than enough.

I have 2 antminer S1 on a Corsair RM850, drawing 730Watt from socket (on 220VAC, 50Hz).
The RM850 can give 70A on 12V rail, so there is enough to spare (because 730 / 12 = 61A not taking into account the PSU losses).
So my conclusion is that a single S1 miner draws about 30A in 12V. A PSU giving 35A should be ideal (to hit max. efficiency).

At the moment I'm using only 2 PCIe cables with dual connectors to power the miners. Cables are cold/lukewarm.
But since the PSU has 5 connectors for 8PIN or 6+2Pci-e I will change this to 4 seperate cables (for some reason only 3 PCi-e cables are delivered with the PSU).

With the Rosewill 450W with free shipping, is 37A at 12v enough to power?

At $60 each, wouldn't be a bad deal - think it would push the PSU too much?

I wouldn't go with the lower rosewill's had a bunch sent to us for hosted machines most of them died in less than a week

Ive figured its prob cheaper and easier to go for 3 seperate power supplies something like corsair 500w and then just have one per miner

That is a reasonable choice

3 x http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027 is 150 usd and is 85% efficient at half load ( http://www.plugloadsolutions.com/psu_reports/CORSAIR_CMPSU-500CXV2_ECOS%202415_500W_Report.pdf ) and you can turn them on and off individually and move to different circuits as needed.

1 x http://www.newegg.com/Product/Product.aspx?Item=N82E16817182063 as posted in a different thread of the same title costs 250 and is a brand I don't really know. But, it will be around 90% efficient at the loads you anticipate ( http://www.plugloadsolutions.com/psu_reports/ROSEWILL%20INC._LIGHTING-1300_ECOS%202330.1_1300W_Report.pdf ). Will that 5% efficiency pay back the extra hundred dollars?

Now, if you are willing to spend 75 dollars per unit, http://www.newegg.com/Product/Product.aspx?Item=N82E16817151136 for a seasonic or http://www.newegg.com/Product/Product.aspx?Item=N82E16817182068 for a rosewell get you the same 90% efficiency at a total cost of 225 USD.

Half the fun of this hobby is figuring stuff out.

I'd be curious about a (2) S1 PSU solution, along with a (3) PSU solution. I saw the 1300 Evga recommendation, but I'm curious about the price vs efficiency - if it is worth it. The price on amazon is $200, which seems like a lot - maybe I'm mistaken

Saying to someone figure it out yourself - kinda defeats the purpose of a forum. Searching provides some answers, but hey, the question is already asked, so let's discuss

Please do the math your self, more than enough info has been provide in this thread alone. Their are tons like it. Search, mining is not for Grandma and Billy Bob.

buy xfx 550 pro bronze
seasonic build
cheap
reliable
efficient
12v one rail
good looking

really good psu, it handles oc ant 205gh/s and 13gh old am blade without problem

i have been using plentyof them, mire than 10 and none died yet.

also tier 1 of course

A single rail 500w PSU is more than enough. But when it comes to PSU's I'd purchase reliability over price any day of the week.

Here's a PSU tier list: http://www.eggxpert.com/forums/thread/323050.aspx

I'm running multiple Corsair CX600M's.... sucks because I had to cut the 8-pin cpu cable and use the screw terminals on one blade each. The power supply has 2 pci-e connectors on one split line, a big no no. All mine are overclocked and running flawlessly. Max draw at the wall for me is 438 watts. YMMV
