Antminer S5 power suply

[Sadczi]

Hi. I just ordered Antminer S5 from batch 1. Here is the specifications:

 
Specifications
Hash Rate: 1155 GH/s ±5%
Power Consumption: 590 W (at the wall)
Power Efficiency: 0.51 J/GH (at the wall)
Rated Voltage: 12V
Dimensions: 298 mm x 137 mm x 155 mm
Cooling: 1x 12038 fan
Operating Conditions: 0 °C to 35 °C
Certified By: FCC / CE
Network Connection: Ethernet 

And my question is: What power suply should i buy to fully use 2 of these on 1 AC? Im mineing a bit but im still newbie in AC suplying.

The minimum you'll want is a EVGA 1300 G2 for 2 S5's (pending that Bitmain's specs. are correct), but if you can find a higher wattage PS for the same price range then you might consider going bigger...

It will be cheaper to buy 2 small power supply, 650 watt each. Unless space is a problem for you I say 2 power supply is better.

Why would he need bigger? It is 590w at the wall only 540w at miner so how do you get 1300w+ from 1080w? I see that will give you some headroom which is nice but other than that no need to go any bigger.

just get 2 corsair RM750 .. 750w per s5 leaves a really nice margin for each

[PeaMine]

Generally want 21% more watts than what it pulls at the wall and only if you don't plan on overclocking or volting.
Very efficient PSUs may need less margin but for the price not a bad idea as it will run cooler and more stable with 21% overhead.

Does the RM750 come with 4 cables to power the S5? If not, where can I get them? Also, is there a cheap alternative to the paperclip method for the on/off 'hack'?

Cheaper than a paper clip???

You can buy the male side of the 24-pin power connector and use that to wire up a simple jumper.  Nothing is going to be cheaper than a paper clip though.

24-pin ATX PC Power Connector

Get 80 plus gold rated or better and full modular if possible. Here's a good choice and Newegg takes Bitcoin

And yes it comes with the cables. I don't own that exact model but EVGA usually includes a Jumper, and the post above mine has one for sale if it doesn't come with one. I've used both paper clips and jumper, in my opinion the jumper is worth the couple bucks vs. the paper clip trick.

[Amph]

one corsair rm can do the trick, a 750w, would be good enough

This is my switch button.

My two S5 will arrive on Wednesday so I was thinking as using my one "Cooler Master Silent Pro 1200W Gold PSU" for both. Will that work? Also whats the difference between Gold & Bronze i.e. which one draws less power?

I don't think that will work. OgNasty review stated that with default setting the power consumption is about 661 watt.

Of course gold draw less power.

just for a moment lets think outside the box :

you dont need a power supply if you have a solar grid with a 12 volt battery.

you connect the solar setup directly to the miner with no PSU needed.

just saying ... buy solar no more psu's and goverment electricity.

[aquarat]

lol @ think outside the box - solar panels are expensive and you can't connect them directly, you need a charge controller and the charge controllers are also expensive.

Just bought four of them on the 15% discount .

[im0rtel]

sir please read again what ive said and let me know where you see the words " solar panels " .

Sounds like a good idea, but anybody tried it?

[sidehack]

sir please read again what ive said and let me know where you see the words " solar panels " .

So when you said "solar setup" and "solar grid" you were talking about some form of local electrical generation using sunlight but not photoelectrics? So what, solar heat into a thermocouple array? Or solar into a steam turbine? In any case, to run a 12V battery off any electrical source (solar or otherwise) will still require some regulation. And since most "12V battery" to be tied into a "solar grid" are probably lead-acid, the charge voltage is more like 13.8V which is a 15% overvolt for this miner. Since its ASIC power lines are unregulated, that means a direct 15% overvolt at the chips which could mean a 30% increase in power dissipation at the chips (assuming I proportional to V) and the whole thing catches on fire.

the 661W number must be at the wall - the S5 spec indicates a draw of about 560-600W on 12V DC. I pushed a unit to 287.5MHz before it tripped my CS650M (gold ATX with 612.5W 12V rail - trips somewhere around 630W) and ran at 362.5MHz 24/7 for several days without issue, indicating about a 600-610W load on the 12V rail

a 1200W (GOLD - most are when over 1200W) PSU should be able to run two S5 units at stock, or if necessary slightly below. A bit of overhead is better (<95% load is a good target for the PSU), so a 1300W PSU would give you that overhead and likely allow a bit of overclocking to achieve 1.21TH/S5

dont o for a PSU any less than gold. The difference between gold and bronze at 90% load is about a 3-5% difference in efficiency (or ~50W on a 1200W draw) If this is ~$3/month more for electricity the savings will cover the higher PSU cost within a year or two, and the supply will be better quality and resale value
