Hetai Tech expansion card

SKU CH-SWF2-8T2K2

M.2 NGFF adapter expands one slot into four PCIe x1 ports with 60 cm USB 3.0 cable and SATA power for mining rigs

  • Adapter typeUSB to DB9 (RS-232)
  • Expands one M.2 NGFF slot into four PCIe x1 slots
  • 60 cm USB 3.0 cable enables flexible riser placement
  • Solid capacitors stabilise graphics power delivery
  • 15U gold-plated contacts improve connectivity and longevity
  • Foam insulation prevents short circuits in dense mining rigs

Mining Riser Board

This adapter converts a single M.2 NGFF slot into four PCIe x1 connectors for GPU mining rigs. It includes a 60 cm USB 3.0 cable and a SATA 6-pin power input. The board uses solid capacitors and 15U gold-plated contacts for stable power delivery. No driver installation is required for operation.

Sustained Mining Operation

Solid capacitors on the riser board help maintain consistent power delivery to all four graphics cards during continuous mining workloads. The 60 cm USB 3.0 extender cable allows flexible GPU placement away from the motherboard for better airflow. Foam insulation on the underside prevents electrical shorts against metal chassis surfaces. Windows 10 limits recognition to eight graphics cards per system.

M.2 NGFF Interface Required

This card only fits motherboards with an M.2 NGFF (key B or M) slot and is physically incompatible with mSATA interfaces. Builders using mSATA or standard PCIe slots cannot install this multiplier. The package contains one mining board, one M.2 riser card, and one USB cable. Additional risers or power cables are not included.

Questions about this item

How much power does the adapter draw when four cards run all day?

The board uses a SATA 6-pin power connector and solid capacitors to stabilise the supply; total draw depends on the installed cards.

Which slot must my motherboard provide for this riser to work?

An M.2 NGFF (M-key) slot is required; the adapter will not fit an mSATA socket.

Will Windows 10 recognise all four GPUs plugged into this multiplier?

Windows 10 supports up to eight graphics cards total, so four on this board are within the limit.
