[2 is fine, still only about 165W per PCI-E.

So each of the 9 hash boards draws about 330 watts apiece?

So the remaining 500-sh watts is for the fans and the controller?

Itll be about 90W for the fans, 20W for the controller and the rest is PSU inefficiency. I calculated with 90% PSU efficiency so at 93 it makes it 170W per PCI-E when using 2 a board.

The product page specifies the controller board must be powered on after the hash boards.

I will use a seperate smaller gold or platinum atx unit, or put a time delay relay inline with the second 2880.
The relay wouldn't void warranty would it? It is still being powered on after the hash boards.

I can't answer that, sorry. Worst case you're frying and paying for a controller, can't be that expensive.

I'm not worried about frying my controller from simply adding a relay. That kind of thing is something I tell people how to do over the phone a couple of times a week. I'm more concerned about posting pictures of how to do so and then having my warranty voided, that is if I went that route. I won't do so for the sake of warranty until I know something in writing from BITMAIN.

I should have been more clear in my reply because I mainly wanted to point out to anyone who hasn't noticed the product specification page states you have to power the control board after the hash boards are started and most people are going to need a separate power supply for doing such until they are shown an easy way to do it. Many people aren't going to know how to do this, that, or the other which accomplishes the same thing. That is obvious from how many people purchase on / off switches for the mobo on / off for their ATX power supply. Not that some don't do it for other reasons, but I am talking in general a lot of people purchase that particular part thinking they need it, or it is a requirement. Remember the thread about the 20 dollar "special" paperclips?

I will shoot a ticket over to support and ask the same question about the relay to test the waters.
