This Add2psu dualPSU powersync extender board is a practical hardware solution for multipowersupply desktop PC and miningrig assembly. It allows users to add a second ATX power supply into one computer system, solving the issue of insufficient powersupply ports when multiple highpower graphics cards are installed.
It connects the main motherboard ATX 24pin signal to trigger the secondary powersupply unit. When the main PSU powers on, the secondary PSU will start synchronously, no manual switch operation is needed. The adapter board provides Molex 4Pin, SATA and 6Pin poweroutput ports, offering extra power channels for graphics cards and other powerhungry hardware.
Compact circuitboard structure fits standard PCcase interior space for quick installation. Please note this board only controls synchronous startup signal, users still need to provide independent AC power input for the secondary power supply.
It is widely adopted for multiGPU gamingrig modification, mininghost assembly and custom industrialPC projects. It is an affordable accessory to expand total power capacity without replacing a single highwattage power supply unit.
