SXDOOL ATX 24Pin to Molex SATA Dual PSU Sync Starter Extender Cable Card
An ATX 24-pin adapter that lets two power supplies start together so multiple graphics cards can share the load via SATA power
- Syncs two PSUs from one motherboard 24‑pin header
- Adds Molex and SATA outputs for multi‑GPU rigs
- Avoids cost of a single high‑wattage unit
- Extends primary PSU life by sharing load
- Keyed connectors prevent mis‑insertion damage
ATX 24-Pin Dual PSU Sync Card
This adapter card lets a single motherboard start two ATX power supplies at the same time. It is built for mining rigs or multi-GPU workstations where one high-wattage unit is unavailable or too costly. The card bridges the main 24-pin connector and a secondary supply so both switch on together.
SATA Trigger for Second Supply
A SATA power lead from the auxiliary PSU plugs into the card and acts as the wake signal. When the primary supply turns on, the secondary follows instantly, spreading the graphics-card load across both units. The package contains only the card itself; no extra cables are bundled.
Check Clearance and Pin Alignment
Verify that the motherboard’s 24-pin socket has enough surrounding space for the card’s bulk. The SATA connector on the spare PSU must be free and correctly oriented before power is applied. Insert the card firmly but straight to avoid bent pins that could damage the supplies or motherboard.

Questions about this item
Will the 24-pin ATX connector or SATA power lead need periodic replacement under mining loads?
The adapter uses a standard 24-pin ATX plug and a SATA power input; inspect both for discolouration or loose pins every few months and reseat if contact resistance rises.
What is the first limit reached when the card runs two PSUs continuously?
The SATA power connector on the secondary supply is typically rated below the 24-pin main connector, so its current ceiling becomes the bottleneck before the card itself.
How much heat or noise does the sync card add when both power supplies run all day?
The board has no active components or fan; it adds negligible heat and zero noise, acting only as a passive signal bridge between the two PSUs.
