Power Adapter for Graphics Cards

This 20 cm cable converts a 15-pin SATA power connector into a 6-pin PCIe plug. It lets a standard power supply feed a graphics card that needs dedicated PCIe power. The 18 AWG copper conductors carry the required current without extra adapters. Plug-and-play design means no software or configuration is needed.

Suited for Simple GPU Upgrades

Builders adding a mid-range card to a system with spare SATA power leads can use this adapter. It is not for installations that demand multiple 6-pin or 8-pin connectors from a single rail. Users whose power supply already provides native PCIe cables should use those instead. The short length only fits components placed close to the drive bay area.

15-Pin SATA to 6-Pin PCIe Conversion

The single specification that decides fit is the connector pairing: a 15-pin SATA power female end and a 6-pin PCIe power male end. If the graphics card requires an 8-pin connector or the power supply lacks a free SATA plug, this cable will not work. Verify both connector types before purchase.

Questions about this item

Will the 20 cm cable add noticeable heat or power loss when running all day?

The 18 copper wire construction keeps resistance low so the short 20 cm run stays cool and delivers full power continuously.

What must already be in the PC for this adapter to work?

A free 15-pin SATA power connector from the power supply and a graphics card that requires a 6-pin PCIe power input.

Can I use this with an older power supply that only has 4-pin Molex connectors?

No, the adapter needs a 15-pin SATA power source; a Molex-to-SATA adapter would be required first.
