The power supply im looking at http://www.amazon.com/Adapter-Power-Supply-LCD-Monitor/dp/B003TUMDWG/ref=pd_sim_op_4?ie=UTF8&refRID=0JXRQGJFNZZSJ9H35RG9
The Rockminer http://www.amazon.com/gp/product/B00KLQHSM6/ref=olp_product_details?ie=UTF8&me=
Another quick question if anyone is familiar with these miners, do i still need to find that special driver online (i forgot the name) or will the device install it after i connect the USB cable?
(If for some reason this double posts im sorry, was having some issues).
that power supply could work the problem is it burns power like a mother fucker. also it may not be 2.5mm on the inside.
