Pros & Cons

Pros

✓ Powers a 6-pin PCIe GPU from a PSU that only has SATA power leads
✓ 2-pack covers two cards, or leaves you a spare adapter
✓ Short 4-inch length keeps extra cable out of tight cases
✓ Latching female PCIe connector resists accidental disconnection
✓ Keyed SATA rails prevent backwards insertion

Cons

✗ Uses up two spare SATA power connectors per GPU
✗ 4-inch reach may not span from the PSU's SATA leads to the GPU in larger cases
✗ 6-pin only, with no 8-pin or 6+2-pin option for higher-draw cards
✗ SATA leads carry less current than a native PCIe cable from a stronger PSU

Manufacturer description

If your power supply has spare SATA leads but no 6-pin PCIe connector, the Cable Matters 6-Pin PCIe to Dual SATA Power Cable lets you power a graphics card without replacing the PSU. Each adapter combines two 15-pin SATA power connectors into one 6-pin PCIe plug for your video card. That makes it useful when you're upgrading an older office PC, a small prebuilt or a retro-leaning build whose original PSU was never meant to run a discrete GPU. The box contains two cables, each 4 inches long, so the adapter adds very little slack inside the case. The male SATA connectors have keyed rails so…

Common buyer scenarios for power supplies & cables of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Will this let me install a graphics card in a PC whose power supply has no PCIe connector?

Yes, as long as the PSU has two free SATA power connectors. The cable joins them into one 6-pin PCIe plug for the card. Your PSU still has to supply enough total wattage for the card.

How long is the Cable Matters PCIe to dual SATA cable?

Each cable is 4 inches long. Make sure the PSU's SATA connectors can reach within that distance of the GPU's power socket.

How many cables come in the package?

The package is a 2-pack, so you get two separate 6-pin PCIe to dual SATA adapters.

Which graphics cards is this adapter compatible with?

Cable Matters lists the GeForce GTX 750 Ti, GT 740, GTX 950, GTX 960 and GTX 980 Ti, Gigabyte GT 610 and GTX 750 models, the Sapphire Radeon NITRO R9 380 and the XFX Radeon R9 290. Any card with a 6-pin PCIe power input takes the same plug.

Will the connector come loose if the case gets bumped?

The female PCIe connector has a latch that locks onto the card, and the male SATA connectors have keyed rails, so both ends hold a secure connection and resist accidental disconnection.
