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.
