PSUBB – 12V PSU Breakout Board for Miners | 6 XT60 Outputs + 6 Fan Headers

PSUBB is a 12V PSU breakout board designed to provide clean, organized power distribution from compatible supported power supplies. It includes 6 x XT60 12V outputs for primary power distribution, 6 x 4-pin 12V fan headers for simple always-on cooling, 1 x always-on 12V low-power output, and 1 x switched 12V accessory screw terminal for low-to-moderate power accessories.

Power can be turned on using the onboard switch or, when installed in a compatible kit or enclosure, through the 2-pin header using an external case power switch lead similar to a PC motherboard front-panel power button connection.

PSUBB is intended to work with tested compatible power supplies. Final amp limits and total available output depend on the specific PSU used and the input voltage supplied to that PSU.

Product Details

• 6 x XT60 12V outputs for primary 12V power distribution
• 6 x 4-pin fan headers powered when main output is on
• Fan headers are non-PWM and do not provide tach/RPM reporting
• 1 x always-on 12V output rated at up to 2A
• 1 x switched 12V screw terminal tied to the main power side for accessory use
• Power on via the onboard switch or 2-pin external switch header
• Designed for use with tested compatible server power supplies
• Note: Available current and total power limits depend on the PSU used and input voltage

Tested / Compatible Power Supplies

• DPS-750RB A
• DPS-1200FB A
• NSTNS-PL11

Watchouts & Warnings

• PSUBB must be used inside the case holder designed for it and secured with two screws. This is required to protect against exposed connectors under the PCB.
• Do not operate the breakout board loose or unsecured.
• The switched screw terminal is for accessory use and is not intended as the primary high-current miner output.
• The always-on 12V output is limited to 2A.
• Fan headers are 12V only and do not provide PWM control or tach feedback.
• This board does not increase PSU capacity. Total safe load is still limited by the PSU, input voltage, wiring, connectors, and cooling.
• Always verify polarity before connecting equipment.
• Disconnect power before installing, removing, or changing wiring.
• Use proper wire gauge, connectors, and protection for your load.
• For indoor use only. Use at your own risk.
