Title: Bitmain S7 + 1300W Power Supply? Post by: Eyedol-X on December 18, 2015, 01:19:56 AM So I know all the reasons why this isn't a recommended combo but what I'm curious is, has anyone done it?
Searched around and can't find anyone that indicates they have done it. I'm not planning on doing it but this was curious if anyone had done it and posted or shared their results somewhere.

1. Hash Rate: 4.73 TH/s ±5% 2. Power Consumption: 1293W + 10% (at the wall, with APW3, 93% efficiency, 25C ambient temp) 3. Power Efficiency: 0.25 J/GH + 10% (at the wall, with APW3, 93% efficiency, 25°C ambient temp) 4. Rated Voltage: 11.60 ~13.00V 5. Chip quantity per unit: 135x BM1385 6. Dimensions: 301mm(L)*123mm(W)*155mm(H) 7. Cooling: 2x 12038 fan 8. Operating Temperature: 0 °C to 40 °C 9. Network Connection: Ethernet 10. Default Frequency: 700M Bitmain recommend a 1600 watt PSU. You may use the 1300 watt if you underclock it a bit, but dont expect to go higher than the default frequency. Title: Re: Bitmain S7 + 1300W Power Supply?

Searched around and can't find anyone that indicates they have done it. I'm not planning on doing it but this was curious if anyone had done it and posted or shared their results somewhere. People do it and it work just fine, but it need to be a good PSU. Personally i'd go with the EVGA G2 1300w, it should handle all the way to 1440W at the wall for a 12/15A 120V breaker limit. With a 10 years warranty, this one is a no brainer imo. Other high quality PSU like made by Seasonic OEM or SuperFlower works too. That include some of the corsairs.

Yeah that's what got me thinking, I have a brand new EVGA 1300w sitting around waiting for my S5's to show up and the S7 just showed up today but I don't have 208V at home to run it with the 2880W PS I have for it Title: Re: Bitmain S7 + 1300W Power Supply?

Its rated and competent for 1300w DC thats fine for 1440W at the wall load. Just keep in mind you lose 1-2% efficiency when you do it, but thats pretty much the one downside. You might need high quality splitter or good dual cables to plug the 10 pci-e tho. Also a 1300w for a single S5 is pretty overkill, i'd run two overclocked ones on that. At 393hz that would be about 1280W at the wall, 1162W feed, so 90% load~. Title: Re: Bitmain S7 + 1300W Power Supply? Post by: Rabinovitch on December 18, 2015, 03:29:37 AM S7 Specifications: 1.

You may use the 1300 watt if you underclock it a bit, but dont expect to go higher than the default frequency. As you well know, hashing speed and power consumption differs from batch to batch. My batch 6 S7 is 4.05 Th and about 1042 W. Now it is powered from 2 Corsair's PSU (1200 W (2 boards+controller) + 1000 W (1 board)), it runs at freq. 650 giving 4.37 Th. At stock frequency it should run fine with one PSU 1200 W. May be I'll try this later. :) Title: Re: Bitmain S7 + 1300W Power Supply?

Post by: fr4nkthetank on December 18, 2015, 02:02:31 PM It can be done with the 1300w, see dogie review of the antminer s7. he plugs only 2 pci per board with the 1300w evga. but this voids the warranty I think. (touching the machine voids the warranty lol). Else get the 1600w evga, its a beast and it has all the pci cables you need, but its expensive. good thing it has the 10 year warranty too. Other than that, you have to get a server psu (loud) on 220v.
