We built this custom smart breakout board to pair with Dell 1400W/1100W Server PSUs and we’ve built it to work as the single power supply for GPU miners. It can power the ATX motherboard and the GPUs, working well with 6 GPUs in typical cases. This smart breakout board includes an Arduino mini and needed interfaces to customize the firmware. This board has a RS-485 serial interface allowing you to control it remotely and also monitor voltage measurements from the 12V bus. Recent updates now allow for multiple PSUs to turn on as a group using the RS-485 Serial Interface. Furthermore, we release the firmware on GitHub so you can customize it yourself.
We’ve included custom wiring harnesses for powering an ATX motherboard and up to 10 SATA power connectors that can be used to power riser cards or storage devices. These plugs include 5V power for full compatibility with all devices.
Dell PSU available as an add-on.
