Key Advantages
- Self-developed 4th Gen Shielded High-speed CablePremium connectors adopted. Supports stable PCIe 4.0 x1 8Gbps high-frequency data transfer. Built-in metal shielding layer with advanced EMI conductive polymer shielding material. Full electromagnetic coverage to block EMI interference, minimize signal degradation and reduce cable weight. Flat cable structure.
- Customizable Length & Low ImpedanceCustom length from 3cm to 100cm. Low cable impedance. Stable full-speed PCIe4.0 performance within 60cm cable length.
- Via-less Differential Signal DesignNo parasitic capacitance or inductance that causes signal attenuation & interference. No CAF micro-short issues, greatly extend service life.
- High-quality High-frequency Low-resistance PCBPCB uses high TG material with 1oz thick copper. Gold-plated edge fingers with sufficient gold content for excellent conductivity. Prevent oxidation and resistance rise which causes crash or audio noise.
- Heavy-duty Reinforced Structure3mm thick PCB gasket protection at soldering joints. Secured with screws & hex nuts. Tensile resistant, anti-interference, avoids broken wires and pad drop-off.
- Low-profile & Extended PCB DesignLow profile PCB will NOT block graphics cards. Extended PCB design simplifies installation and reduces damage risk.
Cable Feature
- Cable thickness: only 1.3mm
- Soft flat cable, bendable without performance loss
- Full EMI metal shielding, anti-electromagnetic interference
Important Notes & Warnings
- Installation WarningPlease confirm the direction before plugging in. Do NOT reverse or offset the connector to avoid burning your devices. Hold the socket firmly during plugging to prevent pin damage.No bending or pulling within 2cm of soldering points on both cable ends.
- Signal Loss NoticeSignal loss always exists with extension cables. Motherboard & hardware signal driving capability varies on different devices. Our lab test result does not guarantee identical performance on your setup. Not recommended for users requiring zero signal loss.
- Device Compatibility RestrictionOlder hardware (over 4 years old) has oxidation & aging risks. Using this riser cable will further reduce stability. NOT compatible with devices older than 4 years.
- Purchase LimitationThis item is intended for purchase by professional engineers only, for laboratory & product testing purpose. Not recommended for general consumer use.
- Sample & Custom Order ReminderFor bulk orders: Please purchase 1~2 samples first for validation before mass procurement.Custom-made product, non-returnable & non-refundable. Please fully confirm compatibility before placing order.
Cable Length Definition
The listed cable length refers to the visible flat cable only, excluding PCB boards and connectors. Add approx 3cm for total length including PCB and connectors.Example: 5cm visible cable = total overall length ~8cm.

Q: Does this cable have shielding?A: Yes. It comes with metal shielding layer with advanced EMI conductive polymer. Full coverage blocks electromagnetic interference, reduces signal degradation, lightweight flat cable design.
Q: How thick is the cable? Is it flexible?A: The flat cable is only 1.3mm thick. It is soft and bendable, bending will not affect normal function.
Q: What is the length definition?A: Listed length is the visible flat cable section, PCB and connectors are not counted. Add ~3cm if you need full overall length.
Q: Can I use it for old motherboards/cards?A: Not recommended for hardware older than 4 years. Aging and oxidation of old hardware will cause instability when using extension riser cables.
Q: Can I buy bulk directly?A: We strongly recommend testing 1~2 samples first to verify compatibility before bulk purchase. Custom products are non-refundable.
