Vszerda M.2 A+E Key to PCIe x4 Riser Extender Cable 100cm internal power cable

SKU CH-MFWQ-2EM0X

Extends an M.2 A+E key Wi-Fi or Bluetooth card to a PCIe x4 slot with a 100 cm ribbon cable supporting PCIe 3.0 speeds

  • Stable PCIe 3.0 8Gbps transfer using German patent wire and Lotes connectors
  • Low impedance cable supports full PCIe 3.0 speed up to 60cm length
  • Differential signal design eliminates parasitic capacitance and inductance interference
  • High TG PCB with 1oz copper and gold fingers reduces oxidation and crash risk
  • 100cm extender cable connects M.2 A+E Key cards to PCIe x4 slots

M.2 A+E Key to PCIe x4 Riser Extender

This 100 cm internal cable adapts an M.2 A+E Key Wi-Fi or Bluetooth module to a standard PCIe x4 slot. It uses German patented wire and Lotes connectors imported from Taiwan to maintain PCIe 3.0 8 Gbps signal integrity. The PCB features a high TG substrate with 1 oz copper and gold-plated fingers for durable conductivity.

Suited for desktop Wi-Fi upgrades, not for storage

Builders adding a wireless card to a full-size PCIe slot will appreciate the low-impedance ribbon and differential signal design without via holes. The 100 cm length suits full-tower routing but exceeds the 60 cm threshold cited for guaranteed full-speed PCIe 3.0 stability. It does not support M-Key storage adapters.

PCIe 3.0 8 Gbps over 100 cm ribbon

The supplier states that cables below 60 cm can run at full PCIe 3.0 speed; this 100 cm sample is longer than that guideline. The differential no-hole layout and thickened gold fingers aim to reduce parasitic capacitance, inductance and CAF micro-shorts that can cause blue-screen crashes.

Questions about this item

Which cable length should I choose for a stable PCIe 3.0 x4 link?

The 100 cm cable exceeds the 60 cm limit for full-speed PCIe 3.0 x4 operation; shorter lengths down to 5 cm are available if you need guaranteed 8 Gbps per lane performance.

What does the 8 Gbps per lane figure mean for my M.2 A+E card in this riser?

It matches the PCIe 3.0 single-lane rate, so an x4 card can theoretically reach its full 4-lane throughput provided the cable stays at or below 60 cm.

Does the M.2 A+E to PCIe x4 adapter limit the slot to x1 electrically?

The riser is wired for x4, so an x4 M.2 A+E card can use all four lanes; the host slot must also be x4 or wider to deliver that bandwidth.
