Key Advantages

1. High‑Speed Shielded CableADT 4th‑generation self‑developed shielded high‑speed cable with premium‑grade connectors. Supports stable PCIe 4.0 x1 8Gbps high‑frequency transmission.
2. Flexible Custom LengthCustom lengths available from 3cm up to 100cm. Low‑impedance cable design maintains full PCIe 4.0 speed stably within 60 cm.
3. Differential Signal Via‑Free LayoutNo vias on differential traces, eliminating signal degradation caused by parasitic capacitance and parasitic inductance. Prevents CAF (Conductive Anodic Filament) micro‑short failures for long‑term reliable service life.
4. High‑Performance PCB MaterialHigh‑frequency low‑loss PCB substrate with precise fabrication. High‑TG base material, 1oz copper thickness, sufficient gold‑plating on gold fingers. Excellent conductivity, reduces system crash and audio distortion risks caused by oxidation‑induced rising impedance.
5. Heavy‑Duty Reinforced Solder JointsEven with durable raw cable, 3 mm thick aluminum gaskets reinforce metal solder points, secured with screws and hex lock nuts. Tensile‑resistant, anti‑interference, prevents broken wires and lifted pins.
6. Low‑Profile & Widened PCB DesignLow‑profile profile avoids physical conflict with graphics cards. Widened & lengthened PCB for easier installation and lower risk of mechanical damage.

Technical FAQQ: What is cable quality? Is it shielded?Fully metal‑layer shielded. Adopts advanced EMI‑shielding conductive polymer material for flat ribbon cable. Every cable trace is fully covered by conductive‑polymer EMI shielding to block incoming/outgoing electromagnetic radiation. Minimizes interference and performance degradation while lowering cable weight.Q: Cable thickness? Is it flexible? Can it be bent?Cable thickness: only 1.3 mm. The cable is soft, bendable and flex‑tolerant for normal use.Important Purchase & Installation Notes

1. Observe correct orientation during insertion. Reversed or offset insertion may burn out hardware. Support the device socket firmly while plugging in, avoid excessive force that breaks socket pins. Do not bend or pull within 2 cm from both cable‑to‑PCB solder joints.
2. Signal driving capability varies across motherboards and hardware. Our lab‑tested performance cannot guarantee identical results on your hardware. Signal loss always exists with any riser cable. Do not buy if you expect zero‑loss perfect performance.
3. Graphics cards and motherboards degrade and oxidize over time. Adding an extension cable further reduces stability. Not compatible with hardware older than 4 years. Do not purchase for legacy devices.
4. Restricted for professional engineers, intended for product testing only. Not authorized for other applications.
