The PCIe 5.0 x16 graphics card extension cable VTC-APEBB003HB27-K2 from ВИТАЛКОНН relocates a graphics card away from the motherboard slot while keeping the full 16-lane PCIe 5.0 link intact. Both ends of the cable terminate to standard PCIe x16 male edge-card connectors with PCI-SIG CEM keying, so one end plugs directly into the motherboard x16 slot and the other receives the gold fingers of the graphics card. With 32 GT/s signaling per lane, the cable delivers up to 64 GB/s of unidirectional bandwidth (128 GB/s bidirectional) — enough headroom for the latest NVIDIA RTX and AMD Radeon GPUs as well as AI inference and FPGA accelerator cards.
Signal integrity is engineered for fifth-generation PCI Express. The PCIe 5.0 x16 graphics card extension cable uses 30 AWG high-frequency copper twin-axial conductors with differential impedance controlled to 85 ± 5 Ω, minimizing reflections and preserving eye-diagram margin over 0.3 m to 1.0 m runs. Multi-layer shielding (aluminum-Mylar foil plus tinned-copper braid) protects each differential pair from the dense EMI environment inside server chassis and mining frames, while positive-locking latches and optional retaining screws keep the connection secure in high-vibration 24/7 installations.
The cable is fully backward compatible with PCIe 4.0 (16 GT/s) and PCIe 3.0 (8 GT/s) devices, so it can be deployed in mixed-generation fleets without link downgrade. As part of the VITALCONN High Speed Cable family, it is manufactured under ISO 9000-certified processes with OEM custom lengths available on request.

PCIe 5.0 X16 Graphics Card Extension Cable Applications
- AI training and inference servers: in 4U or tower servers, extend GPUs from motherboard slots onto dedicated air- or liquid-cooled modules to avoid heat stacking.
- GPU cluster platforms: separate graphics cards from the motherboard on open frames for better airflow, easier cable management, and higher density.
- High-performance workstations: enable vertical GPU mounting and compact or unconventional chassis designs while keeping full x16 bandwidth.
- Edge computing devices: mount accelerator cards on vibration-damped chassis structure and connect them to the core board through short extension cables.
- Test and development platforms: bring boards out to the bench so engineers can attach oscilloscopes and logic analyzers during debug.
Frequently Asked Questions
Q1: Does this PCIe 5.0 x16 graphics card extension cable reduce GPU bandwidth?
A1: No. The cable carries all 16 lanes at the full PCIe 5.0 rate of 32 GT/s per lane thanks to 85 Ω twin-axial construction, so the link trains at x16 Gen5 exactly as a direct slot connection would.
Q2: Can I use it with a PCIe 4.0 graphics card?
A2: Yes. The cable is fully backward compatible with PCIe 4.0 and PCIe 3.0 devices and will train at the highest mutually supported speed.
Q3: What is the VTC-…-K2 part number convention?
A3: VTC is the VITALCONN product prefix and K2 is the suffix assigned to this ODM cable platform. VTC-APEBB003HB27-K2 designates the exact PCIe 5.0 x16 graphics card extension cable configuration — quote this number for fast pricing and samples.
Q4: Are custom lengths available?
A4: Yes. Standard lengths ship from stock, and OEM custom lengths from 0.3 m to 1.0 m are produced to order with typical lead times of 2-4 weeks.
