Power adapter for graphics cards

This 15-pin SATA to 8-pin PCIe cable lets you power a graphics card from two spare SATA connectors on a power supply. It targets builders whose PSU lacks a native 8-pin lead or miners adding extra GPUs. The 20 cm length keeps routing tidy inside compact cases.

Dual SATA feeds one 8-pin plug

Two SATA 15-pin males combine to deliver the 12 V current a single 8-pin GPU connector expects. One SATA lead cannot supply enough amperage for high-end cards, so the Y-splitter is mandatory. The adapter stops working if the PSU cannot spare two SATA ports or if the GPU draws more than the SATA spec allows.

18 AWG wire and short reach

Eighteen-gauge conductors handle the combined load without excessive voltage drop across the 20 cm run. Male-to-male ends plug directly into the PSU and GPU with no extra crimps. The short cable reduces clutter but limits placement to GPUs seated close to the SATA power cluster.

Questions about this item

Will the 20 cm adapter reach from my older PSU's SATA connectors to a graphics card's 8-pin socket?

The cable is 20 cm (7.87 in) long, so measure the gap inside your case before installing.

How can I confirm the 18 AWG wires are delivering stable 12 V power after I plug it in?

Check GPU-Z or your monitoring software for steady 12 V rails under load and feel the connectors for excessive heat.

Does the package include the two SATA power cables needed from the PSU side?

You receive one 15-pin SATA to 8-pin PCIe adapter; the two SATA power leads must come from your power supply.
