Dual PSU adapter for mining rigs

The WRIARICH adapter connects a primary PSU via a 4-pin Molex lead and a secondary PSU via a 24-pin ATX lead. When the primary unit powers on, the board switches the second supply on automatically. It is aimed at builders who need extra wattage for multiple graphics cards or drives without rewiring the case.

Check primary PSU for spare Molex lead

Verify that your main power supply has an unused 4-pin Molex connector to feed the adapter’s trigger circuit. The secondary supply must provide a standard 24-pin ATX plug. No soldering or wire cutting is required, but both units must be ATX-compatible and able to share a common ground through the board.

Passive board runs cool and silent

The solid-state PCB generates no measurable heat and has no moving parts, so it adds zero noise to the system. Its slim profile measures 7.00 by 3.00 centimetres with pre-drilled mounting holes for flexible placement. Power draw is limited to the logic circuit that bridges the two PSU-on signals.

Questions about this item

What connectors come on the adapter and do I need any extra cables to link two PSUs?

The adapter has a 24-pin ATX socket and a 4-pin Molex plug; you only need a spare Molex lead from your primary PSU and the 24-pin cable from the secondary PSU.

The specs list several centimetre measurements — which ones describe the board itself?

The board measures 7.00 cm long by 3.00 cm wide (2.76" × 1.18").

When I press the case power button, will both supplies start together?

Yes — when the primary PSU receives the power-on signal, the adapter passes it to the secondary 24-pin connector so both units turn on simultaneously.
