Will be posting a simple DIY guide for making your own cables for these units soon. If you have a bunch of molex or pci-e laying around from your GPU days you can use them to help power the Gridseed units.
Look forward to this, when will u post it?
There are many guides on here already including guides to powering through PC PSU, See below for some links and some pictures I have thrown on here for using a molex end to plug.

I have 2 miners atm so I am using ide molex entension cables I had lying around to power both and if need be the controller.
The top 2/3 of the forum thread below has molex and PCIE power connector scematics as well as USB
https://bitcointalk.org/index.php?topic=494625.100Ans yes you can wire that pcie cable to your barrel connector, rem the inside barrel is V+ if you have a barrell connector the and if the wires are not color coded inside then on the outside on one of the black's there should be whitish-grey stripes or a solid line, it may be clear it may be faint, but this is the V+ line of the barrell connector. The link I posted above will tell u the scematics of your PCIE, but it is fairly straight forward, you have 3 yellow which ar 12V+ and 4 grounds. Do not wire a control board to this as it only requires 5V+
Also I have a question about the groupbuy does the price include shipping, if not what is shipping to Canada Per unit, Thanks
