i already choos PSU and this is > http://www.fsp-europe.com/professional/fsp700_50arn_88plus.php
. i already have wallet , no problem.
 but i now want know how to should plugg PSU cable that will dont hot and dont burn .

More things you have to consider:

1) Decide where to install your miner. Miners generate heat, they are hot machines. Always in ventilated areas. Never: a closet. Never: textiles or paper or cardboard close to the miner or the PSU. If you need an electric extender cable, use a good one. Always: earth-grounded (3 prongs=yes. 2 prongs=no)

2) Cheap PSUs are also non-efficient. Example: a cheap PC PSU have a efficiency of 60%. S3 consumes 350 watts, but with bad PSU will consume 500 watts. You pay cheap electricity as you said (0.05 USD), but a bad PSU will waste a lot of electricity and money. Example: a PSU with "80 plus Bronze" is more efficient and not expensive

For a mining operation, you will need to learn and decide more things in the next days. Maybe you know this already, maybe not. Just in case:

3) "Mining pool": a) decide which pool you will use. Go to mining pools sub-forum, choose one with happy users. b) sign up in the pool's webpage. c) Learn how to configure your S3 for that pool. Doggie's S3 guide (you have posted there already) should indicate it.

4) You need a Bitcoin wallet to store your bitcoins. a) decide the type of wallet: software wallet (free, but you will ned good internet connection an 50 Gigabytes free in your computer. Example: Armory), cloud wallet (free and easy but not secure. Example: Blockchain Wallet), hardware wallet (highly secure but you have to buy it. Example: Trezor). b) configure your mining pool account with your bitcoin wallet.

5) Decide what to do with your bitcoins: a) save them for a long time, b) use the for commerce, c) exchange them for dollars, euros or your local currency.

6) If you decide to exchange them for currencies, you need to choose an Exchange webpage. a) Choose a trustable webpage. It has to operate in your country, Georgia. b) Check the minimun withdrawal (example: cex.io minimun is 200 euros). c) Check the fees for withdrawals (example: cex.io fee is 20 euros)

If you are that worried you might look at switches for motherboard power.  Here is a example of what antminer made at one time: http://www.ebay.com/itm/AntMiner-ATX-Power-Supply-Jumper-Switch-w-LED-for-PSU-or-Miner-/161421242676?pt=LH_DefaultDomain_0&hash=item259574b134

this cable that will using , in 20 pin jumper

What exactly are you using that cable for?   Is that what your using to turn PSU on?

i heard that this cable more better and safetly > http://www.awcwire.com/Portals/0/CVStoreImages/sfj_stj-type-e-shielded-cable_400.png

it have shield and protects against overheating.

What i have described has kept me safe.  As far as guarantee you are safe I can't as i have not seen your electrical and many other things. But you are on the right track.

And i will be safe ? This something that will make , psu good, good usp and pipetchep right holes

Then you will do fine with just two .   Just use a decent quality PSU.  And make sure to have enough watts to run it.

I undersood ,
No i dont want overclock.

Yes 2 is enough for normal usage.  If you overclock then you depending on freq you might need 4.

Do you plan to run on normal or overclock?

Why connect 4 pci to s3 ?

Only 2 pci dont is enough ?

I highly suggest looking at the S3 thread  and then material at bitmain.  It just seems you have almost every trouble someone can.

On paperclip just search forums, google, anywhere really and you can find how to do it properly.  You have to stick in right holes on motherboard cord or it is bad.

No, Toqchista, no:

Paper clip --> PSU will turn on (without paper clip it will not work)

Good PSU (examples: Corsair, Seasonic...) --> Less risk of accident

Good wiring (4 PCIE connected to the 4 plugs of your S3) --> Less heating of cables  (Note: some PSUs have only 2 PCI-E, some have 4)

so , i will use this paper clip and dont will hot cable and wire

and i will should will choos PSU +12V is 52A.

Yes a metal paperclip is what most use.  Make sure to put it in right holes or you will have a problem. As far as safety if you feel not safe with paperclip, but a switch to turn on motherboard for 5-10 dollars.

And on not burning cable.  Use a decent PSU, not a horribly cheap one.  Also as a general rule dont split a PCIe cable into 2 with those y splitters.

please tell me ,

what do i ? that my s3 dont will burn and cable that dont will hot .

What can I do that I am will safely ?


i should will use this paper > http://upload.wikimedia.org/wikipedia/commons/3/3d/Paperclip-01_(xndr).jpg

You need a PSU with enough watts that your miner is using (depends on freq).   You have  to have 1 PCI-e cord on blade plugged in.  If you went crazy freq having one on all 4 would not be a bad idea.

You might look up how to use a paperclip to turn on the psu.  Make sure to get a tight fit and I also like electrical tape on it to make sure it does not fall out.

As far as heat most of the heat will be from miner and not the PSU.

please tell me, how to wire in PSU that will not hot?

you could also return it, even if it is not directly bought from amazon(you have 30 day to do so, and 14 for contestation)

but it should work out of the box don't worry, vendors from amazon are not scammers anyway

May is that this s3 will be damage and destroy and dont turn s3 ?

People so desperate to mine they're buying things from locations/markets they've never heard of.....

Ahhhh ok I thought you were asking amazon when they would ship.

That is good that they already did.

Amazon.

Why say such ?

 S3 already sent my country, in order is that you s3 is on the way and arives 6 from 9 april

Do you mean amazon?

I warned you it is from third party not amazon on link you kept posting.  Get in touch with amazon and see if they can get seller to contact you if it's not shipping.

AmaOn tell me on mail that you product is on way.

I can sell you two, just pm me and we can talk.

Looks like it dropped 10 bucks to 110 so a little better then the 120 price.

Wish you best of luck.  Let us know how it goes.

already buy. this s3.

It's not the shipping that is dangerous you are buying through your link not amazon but denver bitcoin - http://www.amazon.com/gp/aag/main?ie=UTF8&asin=&isAmazonFulfilled=&isCBA=&marketplaceID=ATVPDKIKX0DER&orderID=&seller=A2JMUGFS4HCQJI

With stock photo you really cannot tell much about condition or anything else of the S3

what ?

amazon linki ?  http://www.amazon.com/1-Pack-AntMiner-S3-441Gh-SHA-256/dp/B00LETT8VS/ref=aag_m_pw_dp?ie=UTF8&m=A2JMUGFS4HCQJI

Where are from exactly?

Dangerous shipping or not?

It's from a 3rd party seller on it.  It's not truly Amazon who is selling the link that was posted.

If something goes wrong Amazon is normally pretty good on helping I agree whether it be 3rd party or direct.

amazon is worldwide accepted, and they offer the best post-customers-service, no need to worry about that

This seller , is some proble that will arrives my country ?

You are buying from a seller selling THROUGH amazon.  It is not amazon selling the item.

You can email or call amazon to ask on shipping.

This amazon s3 really arrives my country if it not ?

There is not a good record.  It is from a 3rd party on your link.  It is NOT amazon selling it.  It is someone selling their miner ON amazon.

With forums you can get a better chance of knowing what item is like.  Also with Ebay you can see pictures of it (on most). 

With your listing having a stock picture, there not a lot we can tell you.

May i find other seller person but shipping my country will be problem.

This amazon link , it is reliable , really arrives my country ?

Is there any reason it has to be that specific one?  I think you might be able to do better on price at other places.

i'm sure you can find a better deal here on the forum

$130 plus shipping seems a bit expensive, without conting electricy you need 4 months to roi(this with free power), which is too much in my opinion

i want will buy from amazon this used s3 > http://www.amazon.com/1-Pack-AntMiner-S3-441Gh-SHA-256/dp/B00LETT8VS/ref=aag_m_pw_dp?ie=UTF8&m=A2JMUGFS4HCQJI

S3 will not be from Bitmain as it is not being made at this point.  You have to get C1, S5, etc to get new one from Bitmain.

Now if you do want a new S5 you could email Bitmain.  If you email them and ask if they can help I would guess they could find a way to make sell happen through email.

And again if S3 best bet is used market.  I would go look at ebay.

I cant buy miner on bitmain , beecause i living georgia and dont exist this country list.

I have a pair of s-3's running 24/7 since July 23 or so.

They are pretty durable. Buying used from amazon or ebay is okay both ebay and amazon give

a short return period.

It's not that it voids the warrenty.  It is most of they have been used to mine where they are out of warranty by the time they find a second home.

I don't think bitmain is actually selling the S3 anymore, I know they are not doing so publicly.

I am also fairly certain that reselling an S3 is not going to void the warranty from bitmain

I think I misunderstood or jumped to conclusion.  I agree with everything you said on last post.  Since we were talking about S3's all at this point are used market.  Meaning chances are it will come from a person company besides in this case Bitmain.

My point was just that from used market most likely no warranty.  If they buy direct from company normally 90 day warranty (varies by companies).  So you get a warranty even if burn in test was very long time.  

It might be a moot point though since S3's were built like tanks and seem to be still working for by far the majority still.

Well yea some companies will burn in for testing purposes, however if a company is shipping immediately then they should be mining with the equipment they are waiting to sell from the time they produce the miner up until the time they actually sell it.

It is expensive and inefficient to start and stop production multiple times so production is done in batches, companies do not produce exactly 150 miners in one day because they sold 150 miners in one day, they will produce 2000 miners in one week because they anticipate being able to sell 2000 miners the following week

In a way yes.  Most companies do a burn in test.   Some are made and shipped out quicker.

But the big difference is direct you get a warranty in most cases.  If you buy used there is no warranty.  So there are differences of buying direct and used.

All mining equipment is used. Whoever is selling it is going to be mining with the equipment they are selling until they actually receive payment for it. This is how someone can sell a miner 'from inventory' as miners are a quickly deprecating  asset. If they do not run them while they are waiting to sell them then they are acting in a financially irrational way.

You should buy from the one who is reputable enough that you will believe that you will actually get what you paid for. If they are both reputable enough so that you reasonably believe you will get a working miner then go with the cheaper one.

Used is okay if the seller is honest.  I believe you can return it if it is dead.

no problem i that will buy used ?

buy the less expensive one, there is nothing more to now about mining equipment

used miner are good they cost less, they should achieve roi faster, but checks your electricity first

which will buy ? used s3 if new > http://www.amazon.com/1-Pack-AntMiner-S3-441Gh-SHA-256/dp/B00LETT8VS/ref=aag_m_pw_dp?ie=UTF8&m=A2JMUGFS4HCQJI


I want more used . is some problem that will buy used s3 ?
