I don't think so:

Aim for 870W I think at full load.
And given it's not an industrial PSU, you'll wear it down quick

Not much point then Sad

. Oh well thanks for the help with my curiousity.

Well after a couple of quick calculations I could run one at 250m and two at 150m and get 1.1th @ 888w. Or one at 225 and two at 175 for 1.15th @ 913w. Or third option all three at 193m which would be just under 1.05th @915w.

What do you guys think?

Having three underclocked would redice the noise to a minimum at an ambient temp of 20c.

I'm just trying to maximise my PSU as I can't have an S5 due to noise levels Undecided

1- 0.829 + 0.817x2= 2463J/Ghs => 2463 /1.1Ths = 2239
2- 0.816 +0.803x2= 2422 J/Ghs =>2422 / 1.15Ths = 2106
3- 0.793x3 = 2379 J/Ghs => 2379 / 1.05Ths = 2265

Option 2 is the most efficient given the difference in Ghs/sec

Thanks for working out the efficiency. So you reckon the PSU would be alright at safe at 913w?

That's what I thought. Is there not freq setting inbetween the 150 and 200? Even on kanos update? (I would look myself but at work).

This is what I get with the latest Bitmain release. antMiner_S320150109.bin

Is it possible to run 3 X s3's on a corsair rm1000? Even if one was underclocked.

Would the under locking reducing the voltage aswell or would it still run at 340w?

you would have to underclock them so much you might as well run 2 at full speed..

150M 302ghs is 247W
200M 403ghs is 323W
225M 450ghs is 367W

so with 1000W you can run 3 at 150M for 906ghs @ 741W or 2 at 225M for 900ghs @ 734W

That's what I thought. Is there not freq setting inbetween the 150 and 200? Even on kanos update? (I would look myself but at work).

this was posted on here somewhere.. cant remember who, but i saved it.. ignore the profit part.. those were the days, where 1 s3 made 2$ a day

Thanks for the reply zOU.

I've opened up a ticket with corsair and asked them. Also do you know where I can get good quality 6pin to 6pin pcie cables?

http://www.corsair.com/~/media/Corsair/download-files/manuals/corsair-psu-spec-table-091813.pdf

page 3 says: PCIe 6+2 pin (GPU) 8

http://www.corsair.com/en/rm-series-rm1000-80-plus-gold-certified-power-supply

tech spec says the same: 8 PCIE connectors

so you should have enough to power both....

as it is a single rail 12V, whatever you connect on the non dedicated PCIE ports will use the same rail, so it should be fine (do NOT take my word for it)

so basically and IMHO it's not worth the hassle...

Hi guys,

Ive got a corsair rm1000 running a standard S3 and an overclocked S3+. The pci-e cables split into 2 at the end but id like to run another set of cables to each miner to spread the load a little better. Trouble is ive only got 2 8pin spaces left on the psu. Obviously I need four. I do have 6x 6pin "peripheral/sata" slots available on the psu though. My question is, would one of these slots supply enough power to run the second supply to a board?

The psu is a single rail type.

Thanks.

Just thought I'd post here that this past week I upgraded the 3 S3+'s I had running in my office for about a year straight. They were run on a single EVGA 1300 G2 power supply that run without problems on 120v (about 1,195 watts for the setup that included 9 additional case fans and a fan controller). The 3 brought in about 8 bitcoins total (running at about 440 GH/s avg.), which I purchased additional miners with about 5 of the coins leaving about 3 bitcoins.

So, did you pay for electricity? If not, that's a huge win. I only mined 1 btc with my 5 s3+s, and 1 of them is running on hybrid solar. You really don't need that many fans imho, because s3+s can run hot and still stay perfectly fine, like s1s. S5s not so much, the reliability has gone down all the way into the s7 series. I run mine in the basement and even at an ambient of 70 they don't get very hot.

I had the 3 in a computer case to keep it a bit quieter for the office. The electricity is included in the office rent, so no electricity expense. I've upgraded to 2 S5's in a case now that's been running for about a week (it's running a bit overclocked and consumes about 1,280 watts for the setup). I would do 1 S7 but it's just too loud. The electricity for the office can't handle more than 3 S3+'s or 2 S5's or 1 S7. I flipped the circuit breaker a couple times a year ago when I tried to run 4 S3+'s, so I settled on the 3 and they ran no problem except the Air Conditioning shuts off in the building after 6pm and on weekends so the office get 80-90 degrees F.
