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.

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

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

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.

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.

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!

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! Tongue

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.

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

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 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

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.

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.

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

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 Cheesy
