Can an electrician help me out.... or armchair electrician!
I'm trying to figure out a custom power setup using ATX power supplies for Scrypt mode only. Would something like this work?
Utilizing 12v PCIe Cables:PSU -> PCIe cable -> PCIe 8 pin to double 6 pin Splitter (could be replaced with 6 pin to 6 pin splitter if neccesary) -> Two PCIe 6 pin to double 6 pin Splitters -> Produces 12 hot and 12 ground wires after cutting off the ends -> 12 barrel plugs per PCIe cable
Utilizing 12v Molex Cables:One 4 pin Molex Cable with 3 connectors -> Splitter all on three connectors -> Produces 6 hot and 6 ground wires after cutting off the ends -> 6 barrel plugs per Molex cable
Utilizing 12v 8 pin CPU Cable:PSU -> CPU 8 pin cable -> Produces 4 hot and 4 ground wires after cutting off ends -> 4 barrel plugs
Assuming I used a Corsair CS750M PSU (
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139061) it would have:
Four 8 Pin PCI-E Cables -> Splitter -> Double Splitter -> 12 barrel plugs each -> Powers 48 Gridseeds
One 4 pin Molex Cable with 3 connectors -> Splitter all on three connectors -> 6 barrel plugs -> Powers 6 Gridseeds
One 8 pin CPU Cable -> 4 barrel plugs -> Powers 4 Gridseeds
58 Gridseeds total powered @ 10 watts each = 580 watts = an efficiently loaded PSU imo.
There is 62 amps on the +12 v rail of that PSU... by my calculation up to 744 watts. So I could probably power more gridseeds if I wanted to? Any ideas of how to add more units easily?? Possibly by adding more connectors/adapters?? using the ATX connector? I liked the idea of using splitters because I can just cut off the end and jam them into the barrel plug connectors pretty easily.

Any ideas to reduce costs??? Source the splitters somewhere cheaper, add more adapters/splitters? etc.
Note: If you try this, it is at your own risk. I'm not positive this will work but I don't see why it wouldn't...Note: If you try this, it is at your own risk. I'm not positive this will work but I don't see why it wouldn't...
