I should hope it works better, that's why I keep complaining when manufacturers don't involve the guy who wrote the software Smiley

Why should they involve you when you fix all their problems for free Wink.

I'm sure they will start to include you once they include the guys building/buying their PSU's into the design process, cause running a PSU at 100% is fine, right?  Roll Eyes

Yep, and even if it draws to much current you would blow up a fuse not your house!

If it has a fuse, otherwise you could pull 32A from a uk ring main until an RCD kicks in at best, at worse, burn your nice carpets. That's why decent power supplies have over current and thermal protection.

Can you do me a favour?

Measure the resistance between the outer pin on the 12v side, and any of the mains pins on the PSU (while it's unplugged from the mains, obviously).

If you get a ANY resistance at all, i suggest people throw the PSU out, mainly because the label says that it's double insulated (box within a box) which means you should have no mains reference at all.

What does this mean? Well aside from the fact that you might end up with mains voltage blasting through to the 12v side of things, it's just bad design for a smps.

Also, if you get told that you won't be getting a replacement, and you are going to bin it, please crack it open and take a load of pictures for us, cause i'm betting it's as bad as the USB chargers you can get which blow the arse out of your phones. The lack of over current protection points to this as well.

Hoping this will get to Bitmain and get them to stop including power supplies with their kit, as it's unwanted weight, and unless they are going to pay top dollar for them, they will just be sending out fire hazards. If we the ability to mess about with cgminer and get the kit mining, we have the ability to buy a psu and plug it in, you know, like with the S1/S3/C1/U1/U2.

The point and what you said are valid, i've seen too many power supplies come from China which can only be called an electrical death trap and/or an EMC compliance nightmare.

Seriously, anyone can get power supplies that can kick out 6A, we don't need power supplies that will either throw out too much RFI or burn someones house to the ground, after all, anyone reselling these in Europe (and I assume other countries, but I wouldn't know) will be liable for it.

These are the same PSUs you buy in the US and EU from Amazon - it all comes from China. We looked at making a no PSU SKU and the price wouldn't make a lot of sense so everyone would buy the with PSU SKU.

1.
Pieh0 is right, there is a big internal difference between a well designed quality psu and a cheap firestarter...
You are welcome to post a full CE check report and PICs from the internal design

2.
It make no sense to pay high air freight cost for a PSU


So please offer them without PSU and let customer decide (if anybody want to buy them ;-))


Since the power brick supplied using the settings they suggest pretty much started melting on me does anyone know of a decent replacement I can pick up off amazon or something?

There's some links in my rbox guides

 Roll Eyes

Is it possible to power the U3s from a Molex with the correct adapter?  I melted, a power supply last night running at bmsc-voltage 0780 --bmsc-freq 1306, which was as high as I could get w/o too many h/w errors

Is Bitman going to replace our burned out power supplies,

Guess that is kind of two questions

Barbara

My thoughts exactly, yxt Smiley

Does this use a web UI like all other Antminers or can it only be used with a direct connection to a Rasb PI or PC??

If Web UI then I will order a box, as could have one running in each room as a small heater for the winter.

Any plans to allow S3 coupons to be used? (would rather use coupons on this, seeing as S3's are more expensive now than they were in August even with a coupon lol).

Thanks

Features:

Scalable: Multiple U3 miners can be maintained by one controller running cgminer due to its USB port.

Hassle free: Setup consists of plugging in the USB and power cables and running Antminer CGMiner.

No, not quite. If the PSU had a C16 on it, you couldn't fit a C13 cable into it and would need a C15 cable. I couldn't imagine them using a C16 instead of C14, but generally when people talk about a kettle plug they're talking about the high temp version.

Ah right, you're talking about the socket side, fair enough, like you said though, it would be hard to see them using a C16 Smiley.

dogie, can you confirm that these things will use a C13 plug instead of the high temp (kettle plug) C15 version?

They're the same thing, apart from one has a higher temp rating.

Get companies like Dell to stop instantly dumping their btc back onto the market (though Bitpay) and you have a deal.

I wonder if I can buy 60 with no psu's. at 30 usd each.

$26 for a plug pack, from China?

Maybe if it was from a top quality company, but lets face it, the rule of buying anything with a power supply from China is to bin it to avoid the explosion/fire.

Just annoys me that they did away with the USB Dongle design, asking buyers to take a punt on something costing £15-20 is easier than £80 (bare minimum) when you consider there are a ton of S1's kicking around on eBay going for less, no need for a pc, and with simple editing of a file, will give more gh/s for around the same amount of power usage (possibly).

Bring back the U1/2 form factor, and you'll have a deal.

I've narrowed it down to when I change the pool info, but I'm using the exact same pool info as all my other Ants (Ctrl C+V right out of a spreadsheet), and cgminer isn't loading once I change the pool info. I've tried just one pool, then the other.
Weird, the Ants don't seem to like my 192.168.0.1 gateway as a dns server, which is what every other computer is set to. Set the DNS to 8.8.8.8, and now it's mining just fine.

Maybe because your router isn't a dns server/forwarder, most routers just send the isp's dns server ip's over DHCP.

Just got another message from Bitstamp...

Quote
sincere apologies for the misleading information regarding your first question.

Bitstamp recently entered in a relationship with a Raiffeisen Bank. That means that both bank account are operational so you can either transfer your funds to our Raiffeisen or Unicredit account.

The exchange rate stays the same in both cases ( http://www.unicreditbank.si/tecajna_lista/?t=1&id_menu=&language=ENG )

If you have any further questions, please feel free to contact us again.

Best regards,
Anžej Simičak
support manager

Hmmm, let's see about the exchange rate shall we Smiley.

**Edit**

Confirmed, it still uses unicredit's exchange rate.

Another reply from Bitstamp, they have confirmed that they are using the prices at http://www.raiffeisen.si/ceniki_in_tecaji/menjalni_tecaji/1 to figure out the conversion.

So for us brits, it's a nice bank to use.

Raiffeisen shows 10000 GBP = 17,086.7286 USD
Unicredit shows 10000 GBP = 16,969.43 USD

Just got to confirm that it's accurate information Smiley.

For those that are wondering, if you want to know how much your money is in $ for transfers to BS, they are using http://www.raiffeisen.si/ceniki_in_tecaji/ to calculate it.

Trying to find out which tab on that page they are using, but at least it's better than their new banks retail rate.

Personally I don't think the FEDs should have the right to auction this off.. I think that the future system needs a way to FLAG coins that are obtained by nefariouse means, and those coins should be put back into the block reward system .. Thats just my opinion .

IMO that's a ridiculous proposition.  Who's going to be the "governing" body on what constitutes coins obtained by nefarious means, and how do you guarantee that the holder of the coins was the one who perpetrated the nefarious act?

You know what this decentralised currency that was built to move away from centralised currency needs? A CENTRALISED GOVERNING BODY!
Maybe while we're at it, let's bring in chargebacks, interest rates for all new coins mined.

What could possibly go wrong  Roll Eyes.

you mean that 4pin to 6pin adapter cannot handle 390/4=95.5W? There are 4 PCIE connectors per each S3 unit. There are 2 PCIe connectors and 2X4pin connectors per each CX500M.

Not sure where you're getting the 4 from, as only 1 pin will be delivering the power, so on a dual molex to 6pin pcie adapter, it will be 195w/16.25A per board, and 65w/5.416A per PCIe pin, but on the molex side 1 12v pin will be pulling 130w/10.83A.

Get them cheap and use 2 adapters per board to split it out if possible.

Or do what Xer0 said below Smiley.

At least you won't have "wasted"/unused wattage per psu, as you can share the current between psu's.
