You can't tell from the outside.  It's the inside.  You have to know the specifications of that particular psu. Most higher end and high end psu will be single 12v rail.

So can i get some examples of 750 and 850 watt PSU's that are single rail?

Thanks,


will 750W PSU work?

Minimum requirement from KNC was 3 x 750W PSU's.

The price difference though from 750 to 800~850 is pretty insane. $75 to $150. Smiley

the ax1200I should be able to run the neptune without any special bootup procedures right?

Based on what Neptune users have reported thus far, you WILL need special bootup procedures for this PSU. See KnC's troubleshooting guide under the heading "PSU powers off when ASIC boards are connected".

If you haven't bought your PSU yet, get EVGA 1300W Supernova G2, good reports so far. Or Seasonic X-1250.
Or, 3 x Cooler Master V850.

Be careful with choosing psu,otherwise you will break your miner.Always try to get the recommended watt.

Im not an expert but maybe it has to do with initial power draw from the asic boards to the psu.   And every psu is not the same how they handle this initial load, which is different than a continuous load draw after everything is running.  It takes more load/torque/power etc  to start something than to keep it going.

I understand what you mean

So what about 2 ax1200is for 4 neptune cubes and then run the controller and 5th cube off of another 800 or so watt PSU -- that would work without any special bootup procedures right?(i'm asking this because my friend has spare ax1200s)

Looks like I'm going to be fiddling with setting up a couple Neppies on Maui, and we have the ax1200's already, lol. Oh well.

This is a repost from kncforum, but they'll take it down soon. If you're still waiting on a refund I would do as this person says and contact these people:

Here is a link to Sweden's English newspaper. Anybody that is waiting for a refund please write to them so that this story gets out:

http://www.thelocal.se/page/view/contact

http://www.econsumer.gov/

You can also file a complaint with Swedish consumer watch dog

Konsumentverket@konsumentverket.se

http://www.reddit.com/r/Bitcoin/comm...t_verket_over/

Anybody else that knows of any links or newspapers to get this story out and to see that we are refunded our money please lets us know.

I don't know if this will work or not. The thing is, the ax1200 just doesn't like to zoom from 0-1000W in a few seconds (or else it shuts off).

Are the neptunes hot swappable to/from the controller.  Plunging them in separately might solve the overload spike problem with the ax1200i

I'd go with 3x AX860's.  You'll save yourself some money.  Basically you have to short pins 4 & 5 from the right on the top of the atx connector.

Super beefy wires.  No problem with volt loss and heat buildup.  The main problem with small pcie connects.   And lack of forethought on KNC to add another one to power the cube.

Why would you ask for a refund? KnC said from Day 1 there would be no refunds on Titans.
