Antminer S5 power suply

[aurel57]

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.

Let me know how long that battery last after the sun goes down...

I am running my S5 on a Corsair RM1000 115v and here is what I am getting:

Freq 375
watts at the wall 635
temps 49/50
fan 3600
1230+GH

When I get time I will switch it over to a RM850 and check the watts to see if it changes

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.

you must be trolling or simply cant understand what a solar setup is so let me spell it out as simple as posible for you .

Everything you need to fully charge a battery is a solar setup . that includes the bloody charger.

with a big enough battery grid i can make a s3 last weeks . but usualy 2 x 6 V  batteries make a s3 run for 24h just fine . a decent 1 KW ( enough for 2 x s3 ) or higher psu is at least 300 usd . thats half of my solar setup cost for a s3. add 300 more and there you go . no more power issues for my s3 forever.

Wow first I thought this thread had to do with a PSU for a S5 not a S3 ?? But I am not sure how large those 6V batteries are but highly do not think they will let you pull even 370watts let alone the 600+ watts needed for a S5 for very long? have you ever left your headlamps on your car and see how fast the battery wear down? Those head lamps are maybe 50-60 watts each. So what is your cost for solar and batteries to run one S5 at 600watts.  The cheapest panels I see from china are about $160 at 45watts output?

i can get second hand panels 240w at 120 usd . this was just a example for a alternative to psu . in my opinion a far better alternative.

Fair enough...but it is a little more involved than what most people think. I can barely keep the miners hidden from the wife now...not sure how I would ever hid all those solar panels!

and you need 4 so 480 usd  at least 4 batterys and a controller  so 600 usd

[mavericklm]

solar, wind are not worth it! unless you pay only 50% or less for the hardware and your state is ''sponsoring'' you with the rest!

[im0rtel]

for a s5 yes i need 4 . for a s3 only 2.

I'm running 2 underclocked SP20's on a Rosewill LIGHTNING 1300W 80 PLUS GOLD and I'm very impressed with the build quality. The modular cables screw on and there are a total of 8 6-pin PCI-Express connectors. I got mine at Newegg for $179.99, free shipping and a $20 rebate card. I can attest that this PSU really can run at 92% efficiency. If I go off what the SP20's say they are pulling and the power at the wall its running just shy of 93% at about an 85% load.

Won't this only run during sunshine?  I thought solar needed a huge array of batteries to run that much power during the night, and read those batteries are hugely expensive.

and plenty of sunshine which we dont see up here in northern Indiana.... if I could just run these miners off of snow....hummmm

I say you will need more than 4 panels...4 will only run the S5 miner during sunshine...if you want to charge batteries you will need more to do that for night time mining.

Right, I would think that if you need say 480W you would need at least 4 - 240W Panels to collect 960W during the sun hours to allow for the 480W needed at night assuming 12 hours sun / 12 hours night. And even if you have that much sun light, those panels only run 90+% efficiency for 4-5 hours of the day around high noon.

[huffdaddy5]

You would be lucky to run a max underclocked SP20 that would pull 350W at the wall and hash 800GH/s, on 4 - 240W solar panels.

[huffdaddy5]

It would take a while for me to offset the cost of the solar when I pay $0.10/kw. 350W 24/7 only costs me $300/year.

[sidehack]

And don't forget a typical charge efficiency for batteries is about 2/3 - so you have to pump 150Ah in to get 100Ah out. Also, where are you shopping to find a 1000W PSU costing $300? I could get you 4-5KW for that.

Solar power is, in general, a good idea. But unless your 12V batteries are exactly 12V (which seems unlikely) you don't want to run an S5 directly off the battery voltage. And solar becomes less and less of a good idea in North America this time of year, when the shortest day of the year was just a few weeks ago. You'd be seeing fractional exposure for a fraction of the day, meaning you'd be living off batteries for probably 18 of the day's 24 hours. So during the good-sunlight hours your panels will have to push 600W to the miner, and an additional 600W*3*1.5=2.7KW to the batteries to charge them up enough to run a 600W load for the rest of the day. Now you're looking at a pretty substantial investment in equipment. Or you could pick up a 1200W server PSU and wiring for $100 and run two S5 off of it.

This is the PSU I buy for most of my miners.  I haven't had any issues and would recommend.

Agreed.  and with luck sometimes as cheap as 150 usd.

Sometimes you can find the Rosewill 750W gold PSUs on sale at Newegg at around $50.
