Dual PSU adapter with LED status

The BQZYX+ Add2PSU adapter synchronises two power supplies so they start and stop together. A 3.3V/12V LED on the board shows the working status of the secondary unit at a glance. It connects the primary PSU through a SATA 15-pin connector and the secondary PSU through a standard 24-pin ATX connector.

SATA 15-pin and 24-pin ATX connections

The bundled SATA 15-pin male plug links to the main power supply while the 24-pin male plug links to the additional unit. This wiring lets the adapter manage extra power for graphics cards, hard drives and cooling fans without extra configuration. Plug-and-play operation means no software or BIOS changes are required.

For builders adding a second PSU

This adapter suits enthusiasts who need more wattage than a single supply can deliver and want simple synchronous control. It is not for systems that run on one power supply only. Buyers who lack a spare SATA 15-pin header on the primary PSU or a free 24-pin socket on the secondary unit should look at other solutions.

Questions about this item

Does the 3.3V/12V LED need any maintenance or replacement over time?

The LED is a solid-state indicator soldered to the board and has no user-serviceable parts; it simply shows the PSU work status.

What limits the adapter when both power supplies run continuously under load?

The adapter passes power through its SATA 15-pin and 24-pin ATX connectors, so the practical limit is the current rating of those connectors and the secondary PSU's own capacity.

How much extra heat or noise does the Add2PSU board add when the system runs all day?

The board itself has no fan or active components beyond the LED, so it adds negligible heat and no audible noise during sustained operation.
