Green circuit board with 24-pin ATX connector and Molex, SATA, 6-pin outputs

SMUGDESK

SMUGDESK Add2psu Dual PSU Sync Board 24Pin to Molex SATA 6Pin Power Splitter Cord

SKU CH-Q0KH-X4WTB

Synchronises two ATX supplies via a 24‑pin trigger and adds Molex, SATA and 6‑pin outputs for extra GPU power

  • Enables dual PSU operation for multi-GPU systems using ATX 24Pin trigger
  • Synchronises secondary PSU startup automatically when main unit powers on
  • Provides Molex 4Pin, SATA and 6Pin outputs for extra graphics card power
  • Compact board design installs easily inside standard PC chassis
  • Expands total power capacity without replacing existing high-wattage supply

Dual PSU Sync Board for Multi-GPU Builds

This SMUGDESK Add2psu adapter lets a second ATX power supply start and stop in step with the primary unit. It solves the problem of too few PCIe power connectors when several high-draw graphics cards are installed. The board is intended for multi-GPU gaming rigs, mining setups and custom PCs that need extra power without replacing the original PSU.

Synchronous Startup Under Continuous Load

The board passes the motherboard 24-pin signal to the secondary PSU so both units power on together, removing the need for manual switching. It supplies additional Molex 4-pin, SATA and 6-pin outputs that stay active as long as the main system runs. Only the startup signal is bridged; the second PSU must still receive its own AC input to deliver sustained power to the extra graphics cards.

Check Your Build Before Ordering

Verify that your chassis has room for a second ATX power supply and that the unit provides the Molex, SATA or 6-pin cables your graphics cards require. Ensure the main motherboard 24-pin connector is accessible for the trigger cable. This adapter does not increase the wattage of either PSU, so confirm the combined output meets the total system demand.

Questions about this item

Will the SMUGDESK Add2psu board generate noticeable heat or noise while the second PSU runs continuously?

The board is a passive circuit with no fan or active components, so it adds no audible noise and negligible heat during all‑day operation.

What existing hardware is required for the SMUGDESK Add2psu adapter to function?

You need a primary ATX power supply with a standard 24‑pin motherboard connector and a second ATX power supply that receives its own AC input.

Can the SMUGDESK Add2psu board power older graphics cards that only use Molex or SATA power connectors?

Yes, the board provides Molex 4‑pin, SATA and 6‑pin outputs, so legacy GPUs using those connectors can draw power from the secondary PSU.
