Hi Edgar.
- "yellow light is blinking 2 times" usually means the miner is up but configured not to mine ("stop mining").  I would recommend finding the miner IP and setting it to mine again.
- If it does not start - do factory reset from settings.
- If the WebUI not accessible or the miner got no IP - you can do the recovery procedure from the technical blog.

Hmm how are you getting such low wattage ?

your temps are higer than mine as well.

my voltage hovers around 236/239
watts are 1350/1340

my Max voltage is .76 and start is at .66/.66


It seems different ASIC require diffrent amounts of power ? 
Other than that hash rate hovers around 4510 similar to yours but with a big higher power consumtion it seems.

Geez, just go buy the most popular PSU for mining ever... the EVGA Supernova 1300G2. Newegg has them for $169 after rebate. I have 5 or 6 of them.

After down time, it seems that miners don't start always autmaticaly.
I have lost 4 hours of mining because the miner did not start automaticaly at power up !

12V, even at extraordinarily high amperages, is only unsafe in very rare occurrences, and its otherwise very safe.
We also will have 3d-printed cases shortly for those that want, and where do you get no warranty? We warranty both the PSU and the board.

Not if you're on 110V, or want a warranty, or don't want to endanger your life with exposed top and bottom LIVE terminals. You posted the same link to your shop a few pages back, so I'll post the same response required.

Will work perfect, and we will hopefully test it on a prototype

What's Spondoolies-Tech post code?

I need it for bank transfer form.

(Wasn't provided with the address Barbara emailed me)

what is this $1095 that keeps mentioned. the price is $1190

Also look for a mid range (used) 1000W+ PSU, not some crazy 1.5kW model which is naturally much higher priced per kW, as quantities are much lower.

you can get a 1200W GOLD PSU for under $200, not sure why you would use the most expensive 1500W possible in your example

i was previously using server supplies, but it meant either needing a $40 breakout board or about 45min of soldering, plus $10-15 worth of pci-e connectors (i sell 24" leads). After that they are often loud and refurbed ones sometimes crap out under high loads.

Since then i made the switch to finding cheap 1000W+ GOLD ATX supplies in the new and used markets and have not looked back. The EVGA 1300W is a quiet, powerful PSU and if you are lucky it can be found used in the $140-160 range (new is $180-200 before taxes)

Most miners either convert server PSUs (with/without breakout boards) or buy USED PSUs with a good efficiency rating.

Either way, you can probably get 1kW of PSU for around 70-100$.

AM tubes are about that price and to get bulk rates with them you only need to spend the equivalent of a single SP31.

Edit: Canary's GB is offering single units so 0.8btc is the most you would for bulk rates.

I have used for anminers the well known server computer PSU sold very very cheep and sometimes more durable than others.
I bought them for 20 EUR each plus the cabling and modification did not cost more than 35 EUR each so
you can do the same if they fail make another one so using two of them will be more than needed as they are 650-800w each.

That is a great read on the market right now. Unless you are buying in BULK  the sub 1 BTC/TH/0.8kW would be possible right? Be interesting to see what sort of volume you would need get that... shipping and PSUs included.

well that would help considerably...let me run those numbers (duh)...off to the calculator again

why I post here people can put me in my place (like in the real world....)

It's 1100W, not 2100W!

what is a fair shipping price to midwest usa more or less..trying to do the numbers on this ..but with say a corsair 1500i at $449.99 newegg.com and say $150 usd to ship and
the $1095 price.that is about around maybe $1694.99 for a 1.7TH unit at 2100 watts .....man at my 15c/kwh it really really hurts ..and even figuring a 15% diff change(s) till
the unit arrives on the doorstep ..say end of Oct....pretty steep loss compared to just buying BTC

I"m all for de-centralizing minning and pushing back against big mining and centralization of mining. and would maybe even take a bit of a loss to contribute to such..

but again with my 15c/kwh ave usa elec price and 2100 watts and the dump of hash/mining farms in the next month of so ...can't seem to get the bird off the ground

I'm sure you will have no issues selling the sp20 to people with less elec costs ..newbie miners etc...but too much to choke down vs buying coin AT THIS TIME

trying to keep an open mind for products down the road...but essentially I can buy 1 1/2 more BTC then I could mine with costs on the SP20 ..so I'm stuck watching
this nice toy from the sidelines er also from my calcs i'm down at least 1 1/2 BTC more or less with elec vs what I pay and with elec if I just mine as well ..a perfect
storm of the asic god's telling me as much as I'd like this unit ....just can't get the numbers to fly on this or any other asic device again AT THIS TIME...

so it goes..

edit see from next post it is 1100 watts not 2100 watts...will re-do calcs it and post here....(duh thats why i post here you guys can correct me) anyway....1100watts
means I would not have to get any power supply (certainly not the corsair 1500i) we will see how close to the mark I get

again looking to just break even ...for the sake of fighting back against centralization of mining (in my meager way) kinda given up of late for making any more
money then just buying coin...so looking at an sp20 from that point of view..now that I have my facts straight I will try this again and post

(could be worse I could be working for NASA ..er...that would have been bad for someone)

The SP20 weighs less than the SP3X and we were able to negotiate better shipping prices. Shipping price the SP20 depends on the destination but is not $200 and certainly not $300.
I don't think this is the thread to discuss ROI but if you insist on doing that at least get the numbers right.
