There is no other way to turn them off but its not a problem and you're essentially doing the same process as on a computer. Software gets itself in order, hard drive does some final shutdown operations, then motherboard flicks the control pin on the 24 pin ATX to the PSU. That triggers the PSU to turn off. You'd be doing exactly the same with your antminer switch.

I have been running them on Nicehash lately. But as I meantioned, I don't have to pay for electricity at the moment. But the circuits are limited, I actually don't know how much I can after all plug into the wall 

I couldn't find out now at all which were good fans to hook up on the S5s to keep them more quiet. And can I power 2 S5s with one EVGA Supernova 1300, or even with a Corsair Platimax 1200i? http://www.corsair.com/en-us/ax1200i-digital-atx-power-supply-1200-watt-80-plus-platinum-certified-fully-modular-psu

you must have low electricity cost. I am actually thinking of cutting down my home mining with ~10.5c/kwh power.

yeah, I don't like to do it too, however, there is some additional power in PSU to slowly ease miner off after you threw the switch-you can see it best if you have a fan powered by molex-it will be several seconds before it stops, so i don't think that it is such a big deal.

If anyone is looking for a 208v PDU   https://bitcointalksearch.org/topic/wts-nib-tripp-lite-pdumv30hv-pdu-metered-208v-240v-30a-05-btc-shipped-sold-927784 

208V will get you better energy efficiency out of your power supplies. You could run 4 EVGA 1300W per 30amp 208v breaker of a PDU. I would use a PDU like this one to distribute your power to the PSUs.

You would then need to buy new cables for your power supply that will plug into the PDU.

If I make the leap to grow my home operation I will certainly go with 208V.

30a x 208v = 6000W, of which you should try to keep the load below 5400W (80% capacity) since mining is 24/7 load. Thats enough to run 4 1300W PSUs, but not necessarily at full load.

1250W draw at ~90% efficiency means the PSU draws almost 1400W at the wall, and 4*1400 would exceed the recommended maximum of 5400W. It would be advised to try and draw 1200W or less from each 1300W PSU

Antminer Products will run on 208v, power source, as long as the PSU you use supports them.

Most of ATX or server grade PSUs are operational between 100v - 240v.  Then, those PSU will spit out 12v from the PCI-E connectors.

Has anyone published out the wattage draw to frequency settings in a chart for 110v?

Also...

I'm considering adding in additional S5s to some 2 Phase 208v 30 Amp Breakers. I have 4 of these circuits just sitting idle in one of my rooms.

Im a little unfamiliar with 208v to begin with, let alone 2 Phase. If I buy the simple distros for the sockets, use EVGA g2 1300w PSUs, how many could I plug in and feed of a 30a 208v 2 Phase?

Thanks!

Unfortunately, the only way Bitmain gave us to turn them off is to turn off the PSU. Yes, it does seem wrong and I hate doing it every time I need to. 

Thanks dogie and biodom!

I think I'm gonna get one of those nf-12. I need the miner a bit more quiet at a longer distance. I can hear it from in my kitchen which is down stairs and around the corner from my stairs and the miner is literally at the top of the stairs. I don't mind hearing it if I'm by my desk or walking up the stairs but not throughout the house. Thanks for letting me know that they are not quiet but from a distance they are not noticeable.

Dogie,

Thanks for the hardware error explaination. So a few hardware errors is almost expected when temps climb, but when hardware errors climb exponetionally, it's a problem. I've cranked the miner up to 300Mhz or about 1Th/s. Temps went up to 61 and 57. Within an hour I got 1 hardware error. It's been at this setting now for almost three hours and still at 1 hw. I like your range of 60-65c it's more realistic to real computing.

Another question...

How do you shut these miners down to say replace a fan or move the miner? Mine came with an antminer motherboard switch. Being a computer geek, I hate just cutting the power. Somehow it feels wrong, but is that what your supposed to do? Just kill the power either with the red antminer switch or the psu switch? Doing this a couple of time switching out fans to try them with temp control lead one board to not respond during initial boot. It was only after full boot and a restart that the board came back online. I can't find a shutdown or turn off setting anywhere, so how dose the rest of you power down your miner for either maintenence or changing a fan?

with  a good old evga 1300 g2 acting as the lube . (well the power source)

@huffdaddy5,

Please check your PM regarding the S5 control PCB.

Thanks for the Ant Porn!!!   

Thank you

Well I've got my 2 S5's running together. Literally. Looks like 1 of my controller boards is not working properly, so I decided that I would make both of my S5's run off of the same controller card.

Here is my Status page showing both S5's running off the same controller board. The temps are little warm but I'm adjusting some fans and I'm powering my fan's externally.

And here is some true to it's name S5 miner porn.

Funny how everyone is worried that the temp figures are out by 5-10C.
The goal being to get the overall temp reading below 60C.
Like dogie mentioned. There could easily be a 15C difference between the BM1384 and the temp reading.
Same as any car. The temp gauge is not reading the engine temp but rather the coolant temp. That sensor is not sitting on the block but in the radiator.
Is the sensor doing its job? Is the engine still running without 'hardware' issues?
My concern is the power regulators. My S1 runs @ 48-51C. The top right corner of the blades have temp readings of 74C.
I suspect I shall have a similar situation when the S5 arrives.
 
 

That's a crit temperature so there's likely to be a safety margin still within that. Say, 15C. So 80C = 110C and 55C = 85C. It could even be lower as the 80C threshold is arbitrary and more of a 'something is wrong if its got this hot' limit.

I would think the actual temperatures may be even higher, as the data sheet for the BM1384 states a max. operating temperature of 125° Celsius.

Probably in the 80s, its hard to tell. I'll see if I can measure the external chip temp at least when I'm next in there.

Hi Eddie,

You're questions are valid, no problem answering them.

1) Hardware errors are only a 'concern' when they become a tangible amount of mining. Historically that was 1-2% but on this generation its more like 0.2-0.3%. You're a long long way away from them being a problem.
2) 80C is considered a critical temperature, where as its recommended to remain below 60-65C in order to increase longevity and reduce the chances of premature failure.

I can't directly answer your question, but I've tested closing top and bottom off. It moves temps ~1.5C, not record breaking, and that's SEALED top and bottom rather than more plates which won't seal.



I would have thought that you're losing more in GPU depreciation than you're mining, surely? What coin are you on?
