Not sure what you mean. I've got a crate full of 2000W 240v power supplies. I can run a whole lot of machines with them and they were much cheaper than pc psus.
Were these second hand or new? and what price range did you buy them?
Most (new) >2kW power supplies for routers/servers I know are often around 500USD or even higher.
But yea better is to wait for KNC's advice on power supplies.
I already asked them if they are going to supply the power supplies but the answer was a probably no.
What I mean is that it would be better for KNC to partner up with a well known server power supply supplier and get us individuals discount on their product some how.
Most of the competition seem to be shipping their miners with power supplies in the box, so it can't be
hard.
