I had this problem on 2 different occasions. I have 3 usb ports on my laptop. The one I had the r-box plugged into had a problem and wouldn't read it. Plugged into a different port and it worked. The second time I had this problem, after 3 days of compiling new versions of cgminer come to find out, the power supply was bad. In both cases it was a hardware issue. Also as a side note, am I correct in assuming you ran zadig?

I started my bitcoin mining experience with $67. Got a rockminer r-box 2. Had an old power supply to power it. Don't listen to the nay sayers, try it for yourself. It's a pretty cool hobby. But be warned, it is very addicting. I've since got 2 antminer s3s, and I'm currently deciding between 1 s5, a spondoolies sp20 or 3 more S3s. The pool you decide to go with will be a big factor on what you make. Also, there are other sha256 coins that you can mine and trade for BTC.(or hold and hope for the best.) Good luck whatever you decide.

Today, after returning from shipping these back to CryptoCrane, there was a delivery from UPS with two new miners in it. So I humbly apologize for any negative comments I made. As soon as I get my replacement PSU in the mail, hopefully, I'll be one happy camper. So again, Dogie and Bitmain I apologize for my words. Now, how can one go about getting their post removed?

I find it pretty hard to believe that both units are bad...we bought 26 Antminer S3's and none of them had any power issues? I would honestly also try powering it from a completely different power source-maybe your home has some power quality issues or something because this story sounds very strange. Also I'm not sure why you would have kept buying new PSUs and blowing them up sequentially?!
Honestly I'd go test the one that didn't blow up your PSU hooked up to a different PSU that's on a completely different power line-like someone else's house or an office outlet or something because I honestly think there's something really wrong with the power in your home or something similar. It's very rare for a modern PSU to actually physically blow up even if there's something horribly wrong with what it's connected to.
I agree this is hard to believe. I did try taking it to a different local. And now I have a dead EVGA 1000w SuperNova G1 (80+gold) which has every safeguard imaginable. There are no power issues in the house we rent. These units are definitely defective. The question is, seeing as how there are no visual defect, what else could cause this? |

But I have had days of extreme stupidity with electrontics. A Marantz monoblock amp comes to mind. I thought the fuses were defective.
* Xian01 places his hand over his heart, as an audio nerd, in a moment of silence for the loss of a Marantz unit I had it repaired cost some cash made a good deal turn pretty sour. @ the op personally I do feel they owe you at least 1 working s-3 be persistent. @ bitmaintech warranty can't you send him some kind of working device? Thank you. But at over $500, I don't see one s3 cutting it. 2 is what I paid for. 1 s5 may get me back toward recovering what I've lost. I just wish they understood the way it works. If we, as a consumer, have more money to spend, then we are obviously going to spend it somewhere. I don't know, maybe in more investments? I've been up for over 32 hours, so I shouldn't even be on the computer right now. I can say this and then i will say goodnight. I do not hate on the big guys, and don't feel anyone else should either. I only hate on the people that effect me negatively. |

One S3 should run just fine even on the most weak shitty PSU. even if the PSU burns, the miner should be just fine, if the connectors are not melted. If there are melted connectors, then it's a bit different.
That's not true. On the way out a PSU won't necessarily stick to 12V as various internal things start turning to goop. you are correct but the op said he could run 3 100gh. r boxes that is about 375 watts. so I am thinking the first s-3 was a bad unit. remember he got the end of life s-3's .---------------------I base this on the assumption the op is telling the truth. If he honestly thought that an S3 had blown up his perfectly good / adequate PSU, why would he put a further THREE PSUs on that unit as each subsequently fails? I don't think we're getting the full story. Yes. You are getting the whole story. My biggest problem is patience. I have none. Old PSU could've been the problem. Or it was the machine. Like I've said elsewhere, I like to be optimistic. I can tell you now, beyond a shadow of a doubt Both of those miners were/are defective. As I said I quit tryin to save a few bucks and bought a 80+ gold. And after last night, I just don't know anymore. I hooked that psu up to my r-box, and this morning I am hashing at 3 G/s tops. Couldn't figure out what was going on, so I took all my gear over to my buddies house and did a process of elimination. And guess what I discovered. It wasn't software, it wasn't the miner, and it wasn't the cables. Only thing left was the brand new EVGA 1000. So, I should probably edit my first post to 5 PSUs. I'm just glad this one has a 5 year warranty. These things have cost me dearly. |

One S3 should run just fine even on the most weak shitty PSU. even if the PSU burns, the miner should be just fine, if the connectors are not melted. If there are melted connectors, then it's a bit different. It might be that your connectors were not good enough and could not bear the current going through them. It also might be the miner's fault, if the connectors are not well soldered. It might be even loose connection between the two connectors.
What model shitty PSU did you use? How is it rated on the rails? What are the other ones?
If BITMAIN claimed they sent you different miners, this is not very nice of them to lie.
Did you send them pics of the miners or did you just mail them to them? I'm asking because many vendors will blame the user if there is something melted.
Going with Gold/Plat PSU is not a must. Yes, it is nice on the power bill but nothing else. On the other hand going with good PSU is a must. One has to read before buying.
This is an interesting case so keep us posted.
The first one was one that I acquired a while ago out of an old tower. Unknown specs, but it was running 3 Rockminer new R-box 100's for my buddy. And I'm pretty sure the S3 doesn't run much more than that. The second one was a Chiefmax (or Cheapmax) 750-watts total ATX form factor 140mm cooling fan with intelligent fan speed control Over-current protection Over-temperature protection 20/24 pin ATX power connector 8 pin EPS+12V connector with detachable 4 pin P4 +12V Six (6) Serial ATA Connector Six (6) Molex power connectors Two (2) floppy drive connection Two (2) 6+2 pin PCI Express video connector Retail Package Includes: 750-watt power supply Power cord Specifications DC Output +3.3v +5V +12V -12V +5VSB Max 36A 38A 40A 1 A 2.0A Min 0.5 0.5A 0.4A 0A 0A The third and fourth ones were Kentek 1000 (ordered the 950) 140mm large fan Quiet Performance and High energy efficiency ATX 12V version 2.3 and EPS12V version 2.92 Spec Intel AMD Spec Matte black color coating and Ball bearing fan and matel gurad grill Mash cable sleeve for easy cable management SLI ready SATA 20/ 24 Pin ATX 4+4 Pin Short circuit and over voltage protection No, I didn't take pics before I sent them. (lesson learned) I was just happy to be getting 2 new miners. Yes, I was told completely new (different) miners. Alas, now I've got a 80 gold PSU with nothing for it to run. And those aren't cheap. I'm telling you, ALL I WANT TO DO IS MINE SOME COIN. Why is that so much to ask? I have kept every correspondence I've had with bitmain. I don't appreciate being shat on. Especially since I had every intention of purchasing more products from them. |

Always go with 80Plus Gold / Platinum PSUs. 1000W or higher is highly recommended initially, until you get the hang of it.
Yes, I've learned my lesson about this. That still doesn't negate the fact that I paid to ship 2 dead miners back, just to have them returned dead. I mean come on, they didn't even try to test them, or they would've known neither of them worked. And then they have the audacity to try and say what they sent me were new miners from a different batch, which is a blatant lie. That's not how a company is supposed to run, I don't give a damn what anyone says. |

same exact miners with the exact same problem
Are you able to describe the problem? Someone might be able to help if you tell us some more info. I can try. Okay here goes, like I said I purchased 2 S3s from cryptocrane. The shipping was fast and the packaging was great. I was sent the wrong PSU, so I couldn't hook both of them up. I had an old PSU from a scrap computer. Hooked one of the miners up to it. After a couple of minutes the PSU was smoking. Okay, must've been a bad PSU. A few days later my other one arrived. So I hook same miner up to it. BOOM! That one blew.(which was a 750 watter) Well, hell I bought 2 1000 watters. They got here and I opened them up, hooked the same miner that blew the last two up, and within minutes that PSU was shot. What the hell? Bad miner, gonna have to return it and run the other one. Hooked the other miner up to the other 1000 watter and wouldn't you know BOOM again. What the hell are the chances of that? So, I figured maybe I was using shitty PSUs, so I broke down and got a EVGA 1000 Supernova G1, got to hook the miners (yes, wishful thinking, I know.) up and nothing. The one that fried the 3 PSUs is completely dead. No fan no red or green LEDs nothing. The second miner's fans work but nothing else. Again no LEDs. Using their guide I tried troubleshooting them and determined that was a lost cause. Got in touch with Bitmain and was told to send them to Colorado. I did. I get them back tonight and like I said they are the exact same miners I sent them. Melted plastic in the connector and everything. Figured maybe the fixed whatever was wrong. Hooked them up and same thing. The one that blew 1 PSU the fan comes on but nothing else. Other one is dead. Now, my question is what the hell was the point of sending them to them if they weren't gonna fix them. Just wasted money on shipping. So, that's about it. Any suggestions? |

Where did you buy from? If you want a warranty you need to buy from bitmain or their official resellers. I got them through cryptocrane, but they are just the middle man. They are warranted for 90 days. Neither of them lasted more than 10 minutes. |

I had issues with the two S3s that I ordered. Got in touch with Bitmain and received the go ahead to return them for RMA. That was 1/3/15. I just got them back about a half hour ago, and they are the same exact miners with the exact same problem. NEITHER of them work. They had good reviews, but my experience has been horrible. AGAIN,I feel they are nothing but CROOKS! And if they aren't crooks, then their management is sub par to say the least.

Not trying to attack bitmain at all. I did a lot of research before buying, and they had the reviews I liked. As far as my troubleshooting, you sound like my buddy. He said I just got unlucky and got bum units. Me being the optimist was hoping it was because I was trying to be cheap on PSUs. As far as asking for advise after 1st one I've read the responses most have and figured that wouldn't do me any good.
It looks like you didn't post the brand name or manufacturer of the power supplies. That can make a huge difference in getting help and identifying the problem. You need to see if the power supplies will work without any load on them. Use the paper clip in the motherboard connector method (examples abound, do a search for the details) and see if the power supplies power on at all anymore. If they do, use a voltmeter to see if it produces 12v on the required pins in the different connectors. Also look at the specs for the power supplies to see if the 12v supplied is on a single or multiple rails. You need single rail. Cheaper power supplies generally are multiple rail which will cause you problems. After you determine if the power supplies will power on at all, then open the S3's and see if there are any obvious burned components or traces on the printed circuit boards. It sounds like the power supply leads/traces may be fused into a short and that may have popped/trashed your power supplies. If there is any obvious internal damage open a support request with bitmaintech and work with them to see if it's a warranty repair or replacement situation. Just a word for the future: you're spending lots of money on a piece of equipment... don't scrimp on the power supply to run it, especially when sellers such as newegg.com have perfectly functional power supplies for reasonable prices and frequently offer rebate or discounts that make the power supplies even more reasonable in price. Look for at least a 500 watt power supply with the 12v on a SINGLE rail, not multiple. For a comfort margin and to operate the power supplies more efficiently, you may want to get a minimum 600 watt power supply. Just as a personal preference, one power supply per miner and I generally use CX500's or CX600's or even CX750's, but not the modular power supplies (they generally have 1 pci-e connector and you need 2 or more if over clocking). If you power multiple miners off a larger power supply and it tanks, you have multiple miners out of service. Yes I'm aware of this. The first 1 was a power supply claimed from an ancient computer. The 750 was a CHIEF MAX 750. I returned that. The 1000s were Kentek. I am not sure what happened to the first, it just smoked and stopped. But the fuse was good. The second one blew a fuse, so I unsoldered the good fuse but that went as soon as I plugged in with no load. So those ones are no good at all until I can get new fuses for them. As far as opening the cases, I did that and everything looks fine. Nothing visually wrong at all. I even went as far at to test for continuity in all the cables, very tedious. As far a Bitmain I am in contact with them. But progress is slow. I now have a modular PSU so each blade gets it's own rail. Also, The one that blew the three got so hot there's still pieces of the pin glued to the connector. I tried using both controllers in each miner and the results were the same. Nothing. I'm not sure if I should be asking for new boards or whole new units. I just want to mine some coin! Can you link to the exact 1000W PSUs you used please? it looks like he used this one.. http://www.amazon.com/KENTEK-Supply-EPS12V-SLI-ready-PCI-Express/dp/B00596TJU2/ref=sr_1_4?s=electronics&ie=UTF8&qid=1420286116&sr=1-4&keywords=KENTEKvery poor rating, not even 80+ has 2 12v rails rated at only 35A, so if he plugged the 2 miners into the pci-e slots he overloaded the psu as soon as it powered on. aarons6 is right that is it. But only one miner on each. And yes they are junk. |

As to the miners themselves, this is probably the first instance of power connectors melting on the miner unit itself. I've not read any postings saying so, but of course I've not read every posting in bitcointalk either. I'd suggest working to get replacement units. Something overheating very badly caused the miners power connectors to melt. Bitmain should be interested in the forensics result on this one. Sorry.. Should read connector glued to pin |

Hello all. This is my first post but I have been lurking for a while. I was wondering if anyone had any insight on this. I ordered 2 S3s from cryptocrane. They arrived in a timely fashion and in good condition. When I got them all I had was an old 600 watt psu. I plugged the one miner into it and before I could configure it, the psu blew. I figured it was old so had to be psu. Ordered a 750 watt psu thinking that would run both. Plugged the same miner in and it blew that one. Okay, strange. This time I got slick (or so I thought) and ordered 2 1000 watt psus. Plugged the same miner in that blew the last 2 and pop, third one. Okay definitely a bad unit. Plug the other one in and I'll be damned, it blew the other psu. That is more than a coincidence. Any ideas? just bad luck or bad units? So far I'm out 120 bucks cause I opened the 2 1000s. Very frustrating to say the least. I then got a evga 1000 watt g1, now one miner's (the second one) fan comes on but nothing else, no led lights nothing. The other one (the first one) does nothing at all.
