Dual PSU Synchronizer Board
The SMUGDESK ADD2PSU adapter lets a second power supply start and stop in sync with the primary unit through the motherboard 24-pin ATX signal. It targets miners and multi-GPU builders whose single PSU can no longer feed every graphics card.
Thermals Noise and Power Draw
The board itself is a passive circuit that adds no fan noise and draws negligible power while relaying the PS_ON signal to the secondary supply. Stable current delivery depends entirely on the rated capacity of each connected PSU, so total load must stay within those limits.
Upgrade Path and Limits
This replaces jury-rigged paper-clip jumpers or add-on relay modules that require manual switching. The jump is worthwhile when a rig expands beyond one PSU’s rating and you need automatic, hardware-level synchronisation without software. It does not increase wattage, so builders who need more total power must still buy a larger or additional PSU.

Questions about this item
How do I install the 24Pin ATX synchronizer board so the secondary PSU starts with the main one?
Plug the board's 24Pin ATX connector into the motherboard's main power socket, then connect the secondary PSU's 24Pin cable to the board. The board passes the motherboard's power-on signal to the second PSU so both start and stop together.
What maintenance or replacement will the synchronizer board need later?
The board has no moving parts or firmware. Under normal use it requires no scheduled maintenance. Replace it only if the circuit board shows physical damage, burnt traces, or the secondary PSU stops synchronising reliably.
What limit appears first when the board runs under sustained heavy load?
The board only handles the 24Pin start signal. The first limit under sustained load is the rated capacity of each connected power supply. Exceeding either PSU's wattage rating will cause shutdown or damage before the board itself fails.
