Re: IN STOCK - OneStringMiner boards, up to 39GH/s, PRICE REDUCED: US$139/€121/€100
My 3* boards have just arrived. My power supply has no PCIe connector, just single positive and negative wires. My question is; what is the best way to wire this to my board?
Should I wire the power supply wires to some sort of adapter and plug into the PCIe connection or would it be better to figure out a way to wire this to the barrel jack connection?
You can do this:Should I wire the power supply wires to some sort of adapter and plug into the PCIe connection or would it be better to figure out a way to wire this to the barrel jack connection?
1. jump start the power supply, by shorting the green wire and the black wire next to it (position 4 and 5 of the connector) with a paperclip, like this:
2. check the voltage on a black and yellow wire with a multimeter, if it's at least 11.8V, the power supply is usable (I picked an old PSU and it showed 11.3V. This means slow hashing, so better get another PSU)
3. Disconnect the mains from the PSU
4. If you're ok with cutting the wires of the PSU, cut black and yellow wires of connectors. Start with a connector that only has black and yellow, then move to connectors with red, black and yellow. Only use the yellow and black wires. Do not use any of the big connector.
5. Strip all yellow wires, bundle the stripped part together and connect to the 12V on the green screw terminal of the middle board of your stack.
6. Do the same for all black wires, and connect to the GND of the green screw terminal of the middle board of your stack.
7. Use the supplied power cables to connect board 1 to board 2 using the screw terminals (red on 12V, black on GND) and connect board 2 and 3 in the same way.
8. Connect the USB cables, start cgminer and then connect the mains again.
9. The boards should start hashing
