2 Pack ADD2PSU Dual PSU Sync Startup Adapter Board, ATX 24Pin to Molex 4Pin Trigger Extender Card for BTC Mining Rig Dual Power Synchronization

This 2-pack ADD2PSU dual power supply synchronous trigger adapter is tailor-made for BTC cryptocurrency mining rigs. It connects the main PSUs ATX 24Pin cable and transmits startup signal via Molex 4Pin port to the secondary power supply, making two power units boot and shut down simultaneously without manual control.

Built with reliable signal circuit components, the board outputs stable trigger signals during 24/7 continuous mining operation, effectively preventing graphics card unrecognition, sudden power-off and mining interruptions caused by asynchronous power supply. Compact lightweight PCB structure occupies minimal space inside open mining racks, keeping hardware layout loose to improve GPU heat dissipation and extend service life.

Only requires matching standard ATX 24Pin and Molex 4Pin internal power cables from your power supplies, plug-and-play without driver or BIOS setup. Fully compatible with all mainstream ATX power supplies and NVIDIA/AMD mining graphics cards.

Sold as a set of two adapters, it is a cost-effective bulk accessory for mining farm construction, computer repair shops and multi-rig batch upgrades to eliminate single power wattage bottlenecks for multi-GPU mining machines.
