Two black PCIe 4X adapter cards with LED indicators and SATA 15 pin power connectors

BucknBear

BucknBear M.2 Key M to PCIe 4X Adapter 2 Pack

SKU CH-SXGJ-TFKQA

Two adapters convert M.2 Key M slots to PCIe 4x with SATA 15-pin power and LED voltage indication

  • TypePro Audio - Microphones
  • Converts M.2 Key M to PCIe 4X interface
  • SATA 15-pin power connector ensures stable supply
  • LED voltage indicator shows active power status
  • Supports PCIe 3.0 data rates up to 8 GT/s
  • Fits 22 mm × 60 mm or 22 mm × 80 mm cards

Dual M.2 Key M to PCIe 4X Adapter Kit

This two-pack converts NGFF M.2 Key M modules to a PCI Express 4X interface for desktop expansion. Each board includes a SATA 15-pin power connector and an LED voltage indicator for stable operation. Mounting holes spaced at 22 by 60 and 22 by 80 millimetres accommodate different module lengths. No driver installation is required on supported operating systems.

Bundled Screwdriver and Screws Simplify Mounting

The package supplies a screwdriver and screws for each adapter so installers can secure M.2 modules without sourcing extra hardware. Breaking the board to fit the 22 by 60 millimetre spacing is irreversible and voids return eligibility. Builders who prefer a single adapter or who need a different keying type will find this kit unsuitable.

PCIe 3.0 Ceiling Limits Throughput

Data transmission tops out at the PCIe 3.0 rate even though the edge connector fits a 4X slot. Systems restricted to PCIe 1X or 2.0 slots will see further bandwidth reduction. Users requiring PCIe 4.0 or 5.0 speeds must select a different adapter.

Questions about this item

Will the LED voltage indicator on this BucknBear M.2 Key M adapter need replacement after extended use?

The LED voltage indicator is a passive component soldered to the board and does not have a user-replaceable bulb or module.

What is the maximum data rate the adapter sustains when running continuously in a PCIe 4X slot?

The adapter supports data transmission up to PCI-E 3.0 speeds, which is the ceiling under sustained load.

How much power does the SATA 15-pin connector draw when the adapter runs all day in a workstation?

The SATA 15-pin power connector provides stable supply; exact wattage depends on the installed M.2 device, not the adapter itself.
