it looks like he used this one..

very 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.

Can you link to the exact 1000W PSUs you used please?

have you contacted cryptocrane? They did sell you the miners at a premium so they should provide after sales service.

if the fuses are blowing that easy, my guess is the wall violtage, are you sure you aren't use a 110v unit on a 220 plug? I know some parts of the world have to use 220 for power on everything, where as those in USA can use 110 and 220

Sorry.. Should read connector glued to pin

Hmmm. I wouldn't be using any of the power supplies you've noted. 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.

 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!  

i want to know where you ordered 2 1000w psus for 120$.. lol..

im thinking this could be your problem..

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.

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. (just look at yours)

     sounds like you fucked up.

     not to blame you  for bad s-3's ,but one blown psu is all you are supposed to do before you post for help.

At this point you claim you killed 4 psu's 3 on the same unit and the fourth psu on the other unit.  So most people here won't be very helpful.  I would be afraid to give you any advice since your procedure

on trouble shooting so far was terrible.   I don't know what to think about your skill set with pc gear, or if you are a shill that opened the account today just  to attack bitmaintech.

 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.

I cant really help you, the ones I have are same temp and RPM and to me they are near silent.  I can't imagine that type of fan even being even capable of 60db.

When loud about 2300 or more rpm. Seen it as high as 2900 rpm. Nothing wrong. My brother's is exactly the same.

There must be something wrong... What is the fan RPM?

Huh?? My S3+ is super loud when hashing full speed and temp around 47 C. It is way louder than 60 db. You must have much lower ambient temps than I do. My ambient temp around 28 to 30 C. When aircon is on it does quiet done a bit.

My S3+ are almost silent. Unless you put them next to your pillow, you really don't hear anything. I also have S3's its the same thing. All the other vendors use fans that are 60+ db which are much louder.

The 12025 is pretty much as efficient as it gets in relation to a sensible fan. In terms of cooling, what other people are doing is replacing them with significantly less powerful fans and running them hotter. In order to retain the same efficiency and long life, there is a certain level of cooling (and so inherent noise) that is required.

Trust me, I bang on about them all the time about minimising noise, and there are tweaks they can do to improve the S3. But the solutions you're comparing the S3 aren't comparative because they run at different targets

the s-3 fans are quiet compared to the stock s-1 or the stock s-5

just downclock the  s-3 to hash at 425gh and they work fine.  I have 2 in my friends office batch 1 been running them since july 22 2014.

If you want to complain about s-3's you can  but they are way better then the s-5

Can you PM me tracking please, and any references you've been given.
