Ruth's sister 24pin dual PSU sync starter internal power cable

Dual PSU sync starter for mining rigs

The Ruth's sister 24pin dual PSU sync starter is an internal power cable that lets two power supplies turn on simultaneously from a single motherboard signal. It is built for miners who need more wattage than one unit can deliver without buying a single high-output supply.

Suits builders adding a second supply

This adapter suits anyone expanding a GPU mining setup where the primary PSU cannot feed every card. It is not for systems that require redundant fail-over switching or server-grade hot-swap behaviour, and it cannot replace a properly rated single unit for stability-critical workstations.

Handles multi-GPU loads split across two units

The cable carries the 24-pin ATX start signal to the secondary PSU via a SATA power tap, so both units power up together and share the graphics-card load. Headroom ends where the combined output of the two supplies reaches its limit or where the SATA connection becomes a bottleneck for very high current draws.
