Multi-PSU adapter for mining rigs

This adapter board lets a single ATX 24-pin motherboard connector control two separate power supplies at once. It splits the signal into eight Molex 4-pin and two 6-pin outputs for graphics cards. A built-in LED voltmeter shows the 12 V rail while status LEDs indicate standby, power-good, 5 V and 12 V lines. The unit measures 9.4 by 9.1 cm and is aimed at multi-GPU mining configurations.

Installation and common issues

Plug the primary PSU into the Molex 4-pin female header and the secondary PSU into the 24-pin female header, then connect the 6-pin leads to each graphics card. An electronic on/off switch toggles both supplies simultaneously. The supplier stresses that connectors must be inserted in the correct orientation; reversing or offsetting a plug can damage the board. If resistance is felt, hold the socket firmly before seating the connector.

ATX signalling limits

The board simply bridges the ATX power-on signal across two PSUs and does not regulate voltage or balance current between them. Both supplies must share a common ground through the motherboard for stable operation. Total available power is capped by the lower-rated unit and by the wire gauge of the Molex and 6-pin cables. No active load-sharing or protection circuitry is present on the adapter itself.

Questions about this item

How do I confirm the adapter is functioning after connecting it?

The LED voltmeter shows 12 V and the four indicator lights — standby, power OK, +5 V and +12 V — will illuminate when the electronic switch turns both supplies on.

What connectors come with the unit and what must I provide?

The board includes one ATX 24 pin input, eight Molex 4 pin outputs and two 6 pin outputs; you must supply two compatible PSUs and the graphics cards.

Which version should I choose for a mining rig with multiple GPUs?

This single model provides eight Molex and two 6 pin connectors, supporting simultaneous start-up of two low-power supplies for expanded GPU power.
