i see there is 3 listings of of the dl580 1300w units on ebay below 20$, just search for "337867-001".
2 of those and you have miles of juice
You can not just plug and play with these can you, wouldn't you have to mod or add something for them to work with most miners?
I'm currently building breakout boards for me to use with this PSU. First prototype will be finished today or tomorrow.
If there is some interest, I can make more and resell them, price should be around 20$ excluding shipping.
I would be interested in 2 if you do produce for sale, can you post a pic once you have first completed?
