## Summary description

Kolink KL-AC-2PSU is a dual/multi power supply synchronization adapter designed to allow two or more PC power supplies to work together. The adapter provides a simple hardware link for simultaneous power-on and shared load distribution, useful for mining rigs, servers, or systems requiring additional combined power. It enables coordinated startup and basic parallel operation without modifying PSUs.

## Long description

Kolink KL-AC-2PSU is a hardware adapter that enables two or more ATX-compatible power supplies to operate together in the same system. It provides a simple synchronization link that allows coordinated power-on of multiple PSUs and basic sharing of load when separate supplies are used to feed different parts of a single computer, mining rig, or server chassis. The adapter does not require modification of the power supplies and is intended to simplify combined-power setups where a single unit cannot provide sufficient capacity.
Advantages
The adapter provides reliable simultaneous power-on for multiple PSUs using a direct signal link, reducing the need for manual switching or custom wiring. It supports common ATX soft-start signaling so both supplies turn on and off in coordination. Installation is straightforward and reversible, with no permanent changes to existing power units. The compact, passive device helps manage high-demand configurations by enabling additional supply capacity while keeping individual PSU loads within rated limits.
Suitable for
PC systems requiring more combined wattage than a single PSU can deliver
Cryptocurrency mining rigs with multiple graphics cards and distributed power feeds
Home or small office servers needing redundant or additional power sources
Workstations with multiple dedicated power lines for GPUs, storage, or peripherals
Key specifications
Function: synchronization link for dual or multiple ATX power supplies
Signal type: ATX power-on/standby coordination
Connection: standard PSU power-on and ground signal wiring compatible with ATX pinouts
Form factor: compact inline adapter for easy integration into existing cable routing
Compatibility: designed for typical ATX power supply soft-start behavior without PSU modification
How to use
Connect the adapter between the power-on (PS\_ON) and ground pins of the primary and secondary power supplies according to supplied instructions, ensuring correct orientation and secure connections. Position the adapter so that cable runs are clear of fans and moving parts. After wiring, apply power and verify that both supplies power on and off together; check voltages at connectors under idle and load conditions to confirm stable operation. If necessary, redistribute peripheral and GPU connectors so that each PSU carries an appropriate portion of the system load.
Usage recommendations
Use the adapter only with compatible ATX-style PSUs and ensure combined loads do not exceed the safe operating limits of any individual power supply. Maintain proper cooling and observe manufacturer guidelines for each PSU. For critical systems or where precise current sharing is required, consider power distribution planning or professional consultation rather than relying solely on parallel operation.
