myVolts ATX 24Pin Dual Power Sync Adapter

SKU CH-BT33-JEMMP

Synchronises two ATX power supplies via a 24-pin adapter and SATA trigger so both units start and stop together

  • TypeAT
  • Synchronises two power supplies for simultaneous on/off control
  • Distributes graphics card load across both units to avoid single PSU overload
  • Relay activates secondary PSU only when main SATA power is present
  • Adapter board carries no load so motherboard remains protected from supply faults
  • Simple plug-and-play 24-pin and SATA connections with keyed orientation

Dual PSU Sync Adapter

The myVolts ATX 24Pin Dual Power Sync Adapter lets a single motherboard control two power supplies simultaneously. It uses a relay triggered by the primary unit's SATA output to start the secondary PSU, distributing graphics card load across both units without the adapter itself carrying main power currents.

Replaces High-Wattage Single Units

This adapter upgrades a system by allowing two standard power supplies to share the load instead of buying one higher-capacity unit. The jump is worth it when an existing PSU cannot handle a new graphics card but a second spare supply is available, avoiding the cost and waste of replacing a still-functional primary unit.

Suits Multi-GPU Builders With Spare PSUs

Builders who already own a compatible secondary power supply and need extra PCIe connectors for high-end cards will benefit. Users without a spare unit, those uncomfortable verifying SATA trigger wiring, or anyone needing a single-cable solution should look at something else.

Perguntas sobre este artigo

Does the adapter need a specific 24-pin socket orientation on the secondary PSU?

Yes — the 24-pin connector must be plugged in the correct direction; inserting it upside down can cause damage.

How is the sync signal triggered between the main and secondary PSU?

A SATA power cable from the main PSU feeds the adapter board, activating its relay to switch on the secondary PSU simultaneously.

What component might need replacement if the relay fails?

The adapter board itself would need replacement, as the relay is built into the PCB and is not user-serviceable.
