Adaptador de fonte de alimentação Kolink KL-AC-2PSU — adaptador de sincronização dual/multi-PSU para combinar duas fontes de alimentação

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.

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.
