Well I finally got my unit,
But my questiion to the users here is which PSU has been confirmed to work and be stable without burning out ?
650W Can run it Stock - Should Hold... maybe.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817153173750W Can run Stock speeds and has 62A Single rail 12v +10$ to 650W unit, worth it because bigger unit will run lower watts from wall.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817153174850W Safe bet and has some room to do OC. Price gets higer but... maybe can get 1500 OC stable with these. I have 1 unit mounted with 2x of This PSU and i start overclocking tests with it tomorrow.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817153158I have 2x 1200W version of this psu, Newegg wont list it. 100A Single rail, bit overkill
http://www.newegg.com/Product/Product.aspx?Item=N82E16817104143You should not try to run single psu. With the price of 1350 watt psu you get 2x 750w and end up taking less watts from wall. ATX powersupply is not designed to run 100% 24/7
This is Stats from my OC unit 3.8% HW-error rate /flex

it eavens out to 230 GH/s maybe 220++ in Eligius
This is running with 2x 1200W psu taking around 960w from wall. Single 220volts plug. 2x Stock psu with stock speeds take more watts from wall.
Some ppl are getting 9% HW rate with stock... psu is not giving enoug? or just bad quality blades. i dont know..
Last photo shows how the Thermal sensor should be mounted. Make sure it's in
hot end of the blades. Some of these miners blow out from front some back
I need to reverse some fans.
