ADD2PSU Dual PSU Synchronous Startup Adapter Board, ATX 24Pin Trigger to Molex 4Pin/SATA/PCIe 6Pin Multi-Interface Sync Extender for High Power Graphics Card Extra Power Supply

This ADD2PSU dual power supply sync trigger board is designed for PCs that need extra power support from a secondary power supply to run flagship graphics cards or multiple GPUs. It links the primary ATX PSU and auxiliary PSU together, so the secondary unit automatically turns on and off synchronously with the main PSU without manual switching.

Different from single-trigger adapters, this board reserves three common trigger interfaces including Molex 4Pin, SATA power port and PCIe 6Pin port, allowing you to pick the matching cable from your power supply for neat internal routing without redundant adapters. The built-in stable signal control circuit delivers consistent startup trigger signals, effectively preventing boot failure, GPU black screen or sudden shutdown caused by asynchronous power supply.

Made of thickened circuit board with stable electronic components, it supports 24/7 continuous heavy workloads such as 4K gaming, video rendering and GPU mining. The tiny slim PCB fits mid-tower, full-tower and custom liquid cooling chassis, keeping internal layout tidy and unobstructed for heat dissipation.

No drivers or BIOS adjustments needed for plug-and-play installation, fully compatible with all standard ATX power supplies and mainstream NVIDIA & AMD high-performance graphics cards. It is a cost-effective upgrade accessory for custom high-end gaming builds, multi-card computing workstations and crypto mining rigs that exceed the load capacity of one single power supply unit.
