Antminer or PSU issue?

[collins6542]

I just purchased an ANTMINER S3 and I am attempting to get it running.. i have a 400W PSU for each antminer S3. I am having issues with the PSU just powering off... I am assuming that it is because it is being overloaded... but I am not sure... Any suggestions, and updates on a better PSU?

That's likely what's happening.  The S3 at standard clock needs 340W from the wall on a decent-rated PSU.  Your 400W PSU probably can't push enough power to the miner.  How many S3s do you have?  I run 3 of them on a single EVGA 1300 G2 and that PSU is rock solid.  Can't say enough good things about it.

Have you tried to get it running at a lower frequency?  This sounds like not enough power possibly.

Also can you tell us model of PSU you are using? Not all PSU's are equal.

underclock them down to freq 150    see if they run .

then run them at freq 175 see if they run.

next run them at freq 200 see if they run.

if your psu can run them at 200 run them at 200
if your psu can run them at 175 run them at 175

if you cant run them at those freq's but freq 150 works then  buy a good psu.


 I would argue a psu purchase if you can run at 175 or 200 is not worth it .

One thing I wonder is with a 400 watt psu if it has one pci-e cable possibly split.   A lot do some cheap stuff in that level.  I hope he tells us psu model.

here is a seller quakefiend420


that would be $92 + shipping for one kit, should be around $20 for a total of $112.


he gave me that quote for a platinum 1100 watt psu.

and I own one from this seller

really nice gear I am running an s-3 on it as I type.

Hey all! Thanks for the information. It was a really cheap PSU... Insignia NS-PCW4050 I have 1 for each S3 miner I have... unfortunately they trip off... I am in the process of changing frequency speed... I did purchase a new 1000 PSU from Amazon that looks like it has some pretty good review... I got a Rosewill RBR1000-M 1000-Watt Bronze Series 80. It arrives tomorrow, it seems pretty nice. There were good reviews on it.

PSU's are honestly a investment you will use them for multiple generations if you pick a nice one.  Some of the low quality ones are even scary to mine with.  The worst use cheap guage wire to split pci-e cables.

If you split a pci-e with cheap guage wire.... and use on a miner you get melting possibly flames.

And if you get a nice psu keep the box and all you can sell it if ever comes to that.  PSU's not a whole lot really changes on.  A nice PSU this year will be a nice PSU next year.  Only advancement I have seen is some more that can hook up to a computer and give some readings.  But that in no way is needed.

Thank you for the information... I will be very happy with the Rosewill I think. From what I read on it, it is a very good PSU...

what price did it cost?

it is a 1 rail 83 amp psu


3 x 6-Pin, 3 x 6+2-Pin  it has a lot of pcie connectors

looks okay if it was cheap price   It is a bronze psu that means it is a bit power hungry.

 It does look like it can run 2 s-3's.

 I figure 1 s-3 at  350 to 450 watts

depends on the clock

The PSU you purchased stated it was rated "Bronze", meaning that it is lower quality than of a "Gold" PSU. When mining, especially 24/7 you will most likely need a "Gold" rated PSU, the cheaper ones tend to overheat, not be able to keep up with the constant demand of power, and puts you at a small risk of a fire.

The ratings on a PSU are just about efficiency of conversion.  The better the rating (bronze, silver, gold, platinum), the more efficient the PSU is in converting the AC power from the wall to DC power to provide to your gear.  You can have a gold rated PSU with crap components, just as you can have a bronze rated PSU with stellar ones.

Rosewill PSUs are newegg's house brand and are generally pretty decent.

  This may or may not be true.

 But Bronze is more about   percent of energy wasted. Not whether it will run 24/7/365

This is more accurate.

I do wish op did not buy this unit not because it will burn or melt (which it may as I do not know the quality of the pcie wires)

The real problem is this will burn about 50 watts more then a good platinum psu

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151120&cm_re=seasonic_platinum-_-17-151-120-_-Product 

I have paid under 100 for these from newegg.

Also there are sellers of platinum server psu's on this site.

I fear the op will spend 1 kwatt a day extra on power that is :
3 bucks a month at 10 cent power
6 bucks a month at 20 cent power.
