ANTMINER S3+ Discussion and Support Thread

[aarons6]

This thread is ridiculously long, so this has probably been answered but I'm not sifting through that many pages. What is the proper PSU wiring for overclocking? Is it possible to power with two PSUs? One at 500 Watts and a second at say 150+ Watts?

You can use two power supplies as long as each board is connected to only one PSU. I.e. one PSU for the left side, another PSU for the right side is ok.

Better yet, get a 600W+ PSU with 4 PCI-E connectors and you'll have less clutter.

This any good?

im gonna say no, it doesnt even have a bronze rating?

Thought it did, but double checking looks like no.

Seems the CORSAIR CX750M is the cheapest option I can find. Nothing in the 600 or 650 watt range seems to have 4 rails.

Why do you need 4 rails? I've been using Corsair RM850 that have a single 71A 12V rail to run 2 OC S3+ for months without a problem. I''ve even pushed them to 875W without a problem. Currently running 5 S3s and 8 S1s (undervoltaged to reduce hashrate but increase efficiency) on 4 Corsair RM850.

As long as it is a high quality power supply one high capacity rail is superior to two or four lower capacity rails.

I think someone needs to learn the difference between 4 Rails and 4 Connectors. Before they melt down a shiny new miner and blame it on the manufacturer.

i wanted to check how many rails my PSU had, but when i peered in, i noticed there was a train coming and had to jump out of the way.

This is why these manufactures need to be providing power supplies. I've never gotten the point of not providing one. Other than to make it difficult to figure out what the hell you're doing.

Because standard ATX PSU's can be used with next gen miners instead of having to pay for a new PSU every time you upgrade.

Because most miners already have a fleet of PSUs and don't want new ones with every miner?
Because most mining rigs ship from China, and miners don't want to pay to ship an extra several pounds across the planet?
Because a manufacturer would sell the rig+PSU at a profit, whereas most of us find extreme deals on PSUs and then buy a case of them at 50-75% off from retail?

If you really need a PSU and a completely set up rig, there are resellers that do that. Resellers are better in that situation because they usually provide local (i.e. English) tech support, don't require you to install QQ and speak Chinese, and are awake around the same times you are if you do need assistance.

So what I'm saying, is no one wants manufacturers to bundle PSUs with their rigs as a default. And those who do, don't actually want to be buying from manufacturers, they want to be buying from local resellers.

And if you get a good deal on a high quality Gold, Platinum, or Titanium PSU, they will last for years.  I have some Corsair RM850 golds on their 3rd miner.  I really don't want a new $100 - $250 PSU for each miner.

*EDIT*   Most, if not all, miners use the PCI/E power connector.  It is a 6 pin connector with 3 pins +12volts and 3 pins ground.

They could have an option to sell a power supply as an addon item. However, unless it's a well tested and known brand (if not built in house), you can get fires and potential law suits as we've already seen from bitmaintech.

And don't forget ASICMiner's flaming Prismas. Those are nice for keeping your house warm around Christmastime.

It is a really tough one for ASIC manufacturers.
1. An autoranging PSU 100V-240V rated @ max 550W will only provide the max power at the top end voltage, and though the PSU may be able to power your ASIC rig from the lower end voltage, it will be stretched and most likely die on you gracefully or probably go out with a bang! So they can choose to put at autoranging one rated @ max 750W, but this is an over-specified PSU for the higher voltage countries.
2. Most users want to (and do) OC their rigs, so a lowly specced PSU will most likely be overstretched to the expense of the manufacturer.
3. Better to specify the power needs of a rig and let the customer source a PSU from the local market to power their rig.

Having said that, redistributors tend to stock and offer PSU's matched to the rigs they sell that do not ship with manufacturers' PSU's. At the end of the day, whether you buy a rig with a manufacturer PSU or from the ocal market, you will still pay for the rig. in the case of the latter day bitmain shipping charges, I'd err on the side of sourcing my PSU locally rather than have the manufacturer whack me with a great big shipping bill!

Received my 4 s3's 3 fire up fine, however 1 is displaying the following.

Ive swapped PSU's and cables
Opened up and swapped chain cables around and still only chain 1 fires up.

Anyone seen this problem and any advice?

Cheers

if resetting the power doesn't fix it then I would RMA the unit, at times one of my boards stops working too after 1 - 2 weeks of uptimes and so far thats all I had to do to fix it.

are you sure you have both sides of the miner powered?

you only need 2 plugs, but they have to be each side. not front and back.

why is it difficult to look at a guide for the product to see the reccomended PSU wattage (Generally a 650W+ is recommended for an antminer S3+)? Its pretty common sense on how to wire up a few PCIe cables and understand that a GOLD/PLATINUM ATX supply with a single 12V rail and sufficient wattage is required.

It makes no sense to buy a PSU (lets say a $60 Corsair CS650M) thats located in china, pay to ship it to your country (~$25), pay import costs ($10), and quite possibly not even receive a compatible power cable for your country with it. So now a PSU that costs $60 locally is received days later for $95+       why does that make any sense?

if you dont want to set up a powersupply, buy a complete solution miner like the S4 or the SP31

[pekatete]

Bitmain - when are you going to consider selling the S3 boards on their own, i.e with neither heatsink nor control board? This will reduce the shipping cost and make it viable for us small time miners to get bigger (and therefore better for the bitcoin eco-system). We can then source our own heatsinks cheaper either locally or even cheaper from your very own locality!
I would certainly buy a few boards every so often and you'd keep the pennies ticking over on your side too!

PS. I have discovered that the voltage setting on the new S3+ firmware can be tweaked to increase hash speed (sometimes in conjuction with tweaking the timeout). Is there a bounty on this as I wish to collect  ?

this will never happen.. why? because in a week there will be another company selling bitcoin miners with their boards in them, maybe even cheaper then they do..
