Hi everyone,
If you're planning on running units that require barrel plugs, my company has worked to create a line of PCI-E to barrel plug connectors that power quite a few mining devices. We just added 2.5mm plugs for RockMiners, so I figured it would be a good idea to promote them on BitcoinTalk:
Features of each cable:
- 18 AWG Per Cable (Good for up to 12v/5a)
- 3ft / 100cm Per Individual Cable
- Solid Construction (Observed defect rate = 0.1% on PCI-E Molex connector, 0.2% on barrel plug being wired incorrectly from manufacturer)
PCI-E 6-Pin to 3x 2.1mm DC Barrel Plug:
PCI-E 8-Pin to 4x 2.5mm DC Barrel Plug:
CompatabilityThese power cables should work with all devices that require a 2.1mm or 2.5mm DC barrel plug connection. This means that the 2.1mm DC plug will work with 5-chip Gridseed Miners, Gridseed Blades, and ZeusMiner Blades. The 2.5mm DC barrel plug works with RockMiner RK-Box miners, and theoretically works with Gridseed/ZeusMiner as well, but we would suggest using the appropriate cable for the devices.
Using barrel plug splitters, we've managed to power 12 Gridseed 5-chip units from one single PCI-E 6-Pin unit, and have been able to run >50 Gridseed 5-chip units on a basic 500w ATX power supply. IMO, its easier to set up and run units this way as opposed to splicing server PSUs.
