They probably only have 1 pci-e cable with 2 connectors 

Eh what?  I have a single Corsair CX 600 Watt ( ~58/ea ) per AntMiner and overclocked (Edit: @400) they pull ~420 Watts via KillAWatt.  Why would you need 2x 600w per AntMiner?

so you have 10 600w PSU's
so that lot will be pulling 6000w Max

i have 1 1500w running 4 Ant miners
hmmm i would who is going to win in the long run lol

Nice looking setup, here is a question that has been bothering me for a while, Why pay £239 for a 1350W Psu when you can buy a budget 600w PSU for under £20 Delivered ?

I run all my ants blades with there own PSU. I take it I must be mad or something, fair enough it takes a bit of room but will it not be cheaper as the PSU will only be pulling what it needs ?

I have 5 ants in total so that's 10 600w PSU's.

Going to get a multi meter to measure what it is pulling all my miners are running between 205 and 210 Gh/s

Cheers

Well
i have 4 Antminer S1's running from 1 PSU



the PSU is a
Silverstone SST-ZM1350 Zeus Power Supply - 1500W Peak
http://www.overclockers.co.uk/showproduct.php?prodid=CA-315-SV&groupid=701&catid=123&subcat=2464


its pulling 1380w at the plug

No heat issues at all

All the miners have been OC'ed to 375.

and its been running like that for 2 weeks now

it is much costly, because difficulty rise 100% every month, currently I can pay about 2 usd per 1Gh/s.

Hm, very strange. Which model PSU? Corsair AX860 or AX860i? Only thing I could see is that maybe the PCI-e connectors had loose connections (even if well clipped) which increased the resistance and heat per pin.

That should not be possible if you plugged them in correctly. Each blade will draw approximately 185w DC when overclocked to 400MHz. You should have each blade on it's own wire.

My configuration:

AX860i

1x Dual 8 pin PCI-e connector (only one pin used on one blade, other 8 pin unplugged)
1x Dual 8 pin PCI-e connector (only one pin used on one blade, other 8 pin unplugged)
1x Single 8 pin PCI-e connector (powering one blade)
1x Single 8 pin PCI-e connector (powering one blade)

If you're powering two blades on one single dual 8 pin PCI-e connector then the result will surely be a melted plug at the PSU end.

Each connection had its own pci connection. With a load of about 175w per cable.

In all fairness the psu in question was heavily used. I had three 860w fail in the same week, all were RMA and replaced.

Did you use the dual strands, or single strands on the PCI-e?

I melted the pci connections running two ants on an 860 platinum and that was without OC. Load of 720 -750watt.

Running them on OC will kill your psu

I thought the rear fan was supposed to be an exhaust....hmmm but hey if it works and make more power sweet....

btw, speaking of fans...I am having issues on 3 of 6 ANTMINERS received in this last order with what seems like bad/dead fans....

so on one unit the Antminer was running perfect, other than this unit had a particularly louder than usual fan for one of these rigs, the it stop running and of course the unit stopped mining and started beeping (awesome safety feature). So I thought bad fan, wrong, run good when testing it on the 2nd FAN PWN connection on a running unit...
so then I though bad power supply, wrong....

test a known good antminer, and it power up and mined perfectly....
then I started test the unit and found out by accident that just as I disconnected the fan it moved...I saw that and started messing with the plug and got the fan to work....Somehow if I shove the fan connect all the way down it won't work....I thought it was a bad/bent pin, wrong, then I thought a bad pin in the fan connector, wrong again...If I dangle the fan connector just right, it will run and the rig will mine, but if falls or is not a good connection or I shove it all the way down, no fan = no mining

same for the next 2 units. EXCEPT 1 unit did run with the fan connector all the way down and I could see the FAN RPM's in the web browser, but now I cannot. While it did run, unit 1 did have a weird burning smell....so I am concluding that these are not the same fans that came in earlier batches....and that maybe the speed sensor/control on the fan has burned out...and that was the burning smell....
and the fan works when I dangle/connect it just slightly to give power but not to the sensor???

thoughts, suggestions fixes ideas are welcome. I am ordering some new fans which are not as easy to find as some say, I did order one before and it was the right dimension, slightly wrong connector and pinned out wrong ( i had to swap the pins around in the fan).  

thanks,
sbfree

ps. these 3 units are currently running, but I can't see fan RPM's nor can I shove the connectors all the way down or fan stops as soon as  I try to do that.

Correct me if I am wrong but the price for the 500 Ants needs to be updated still so please hold off as the price has now been updated since the 2.2BTC Ant S1

Also with the wait for next dispatch the 8th.

I hope bitmain opens an online customer service based chat or ticket support would be a great way to take the company forward as the have the product,price and delivery they just need the customer service to match then they will be the best all round ever Bitcoin mining company

I see many order already flooding into the Bitmain wallet....  

Here's hoping! Just hope their new products don't make me regret my purchases! 

Bitmain,

I forgot to apply my coupons on order 00120140129142321525yc182XxE0679 so I did not pay it. Please cancel the order as I have placed and payed a second order with the coupons applied.

New valid order is 00120140129142444626o9aRRvb406AE


Thanks! Another TH of ants between you and I.

No problem I'm sure Bitmain will make new thread or update first post and update message.

Hopefully we see a new product come out... maybe 20/28nm chip ? Bitmain has us all on edge

Cheers

edgar, my 2 cents, and I have and have had a few, and some run perfectly but show all x's...if thats the case it's probably software glitch...I usually don't anymore, but a reboot def. makes it go away ( for a while). maybe a firmware update, but I am not risking it.

I haven't had a bad unit with bad chips, but if it nowhere near 180GH/s, then that is a prob. for sure....

  happy for you

Thanks Crover, just ordered 3 more. 

x 2 S1 for mw Thanks
