Ruth's sister SK4 internal power cable

SKU CH-FY28-ZRZR6 MPN SK4

Connects an M.2 NVMe SSD to a PCIe 3.0 x4 slot, supporting 2230 to 2280 sizes with signal enhancement

  • Connects M.2 NVMe SSDs via PCIe 3.0 x4
  • Supports drive lengths from 2230 to 2280 mm
  • Fits PCIe x4, x8 and x16 slots
  • Tantalum capacitor keeps voltage stable
  • Includes screwdriver and mounting hardware

PCIe 3.0 x4 M.2 NVMe adapter

The SK4 adapter converts an M-key M.2 NVMe SSD into a PCIe 3.0 x4 add-in card for desktop motherboards. It accepts drive lengths from 2230 to 2280 and fits PCIe x4, x8 or x16 slots. The board does not support M.2 SATA drives, so buyers with SATA-based NGFF modules cannot use it.

Thermals and power

No active cooling is included, so the SSD relies on case airflow and the motherboard slot for heat dissipation. Power is drawn directly from the PCIe slot through the onboard voltage-regulation circuit with tantalum capacitors. The supplier states the design adds no POST delay during motherboard self-test.

Build and connectors

A gold-finger PCIe edge connector mates with the motherboard while an M-key M.2 socket secures the drive with the supplied screw and nut. The package includes a small screwdriver for installation. The five-year factory-outlet warranty covers the adapter board itself.

Questions about this item

How do I install the SK4 adapter and what is the common mistake?

Insert the M.2 NVMe drive into the M-key slot at 30 degrees, secure it with the supplied screw, then plug the card into a PCIe x4, x8 or x16 slot. The step often missed is using the standoff nut to match 2230, 2242, 2260 or 2280 drive lengths.

What maintenance or replacement will the SK4 adapter need later?

The on-board tantalum capacitor handles constant-voltage filtering and requires no scheduled replacement. If the adapter fails, the whole card is swapped; there are no user-serviceable parts.

What limit appears first under sustained use on the SK4 adapter?

The PCIe 3.0 x4 interface caps throughput at the Gen 3 x4 ceiling, so heavy, continuous I/O hits that bandwidth ceiling before the adapter itself overheats or throttles.
