HOOCCC PCIe 4.0 x16 High Speed Flexible Extender Card, EMI Shielded 30AWG, TPE Cable Sleeves, Pcie 4.0 Riser Compatible with 4090 4080 4070 3090 and PCIe 3.0

PCIe 4.0 x16 Vertical GPU Riser Cable 90° Right Angle, Silver-Plated Shielded Extension Cable ([XX] cm, Black)

Show Your Graphics Card, Not Hide It

Vertical GPU mounting has become the signature look of modern builds, and this PCIe 4.0 x16 riser cable makes it possible without giving up a single bit of performance. Instead of letting a heavy graphics card sag horizontally and bury your RGB lighting behind a shroud, mount it upright against the side panel and turn it into the centerpiece of your system. The 90° right-angle connector positions the card parallel to the motherboard while keeping the cable run clean and controlled.

True Gen4 Bandwidth, No Compromise

This is a genuine PCIe 4.0 x16 riser, not a rebadged Gen3 cable. It delivers a full x16 link at up to 32GB/s per direction (64GB/s bi-directional) roughly double the bandwidth of PCIe 3.0 so bandwidth-hungry workloads such as 4K/8K gaming, AI model training, 3D animation, architectural rendering and multi-track video editing run at full speed. The cable is fully backward compatible with PCIe 3.0, 2.0 and 1.0, which means it also works perfectly in older builds or when paired with a Gen3 GPU.

Signal Integrity Built From the Inside Out

PCIe 4.0 operates at 16 GT/s, and at that frequency cable construction is everything a poorly made riser will drop the link to Gen3 or cause random black screens. This cable addresses every weak point:

1. Silver-plated conductors with Teflon insulation lower signal attenuation than standard tinned copper, with excellent heat and aging resistance.
2. Aluminum foil shielding blocks external EMI and reduces crosstalk between adjacent pairs.
3. 6-layer high-frequency PCB with a low-impedance, low-dielectric design, specially optimized for Gen4 trace routing and impedance matching.
4. Thickened electroless gold-plated fingers resists wear from repeated plugging and unplugging, maintains stable contact and reliable conduction over the long term.
5. Integrated injection molding with UV glue curing the joint between cable and connector is the most common failure point; here it is machine-welded, encapsulated and cured for strain relief and long-term reliability.

Every unit is machine-assembled and goes through an 8-step inspection process with 100% pre-shipment testing, so what arrives is verified, not sampled.

Ultra-Thin, Flexible, Easy to Route

The flat, ultra-thin cable body bends and folds without kinking, letting it slip into tight spaces behind a motherboard tray or around a PSU shroud. Multi-position adjustable mounting holes on the bracket give you freedom to fine-tune GPU height and alignment across a wide range of ATX, E-ATX and mid-tower chassis. At just 18.5mm in height, the connector adds no bulk and does not block adjacent slots.

Locked In, Stays Put

A high-performance connector with a rear locking latch grips the graphics card firmly, preventing the slow loosening that vibration and gravity cause over time a real risk for heavy flagship cards mounted vertically. Once seated and latched, the card stays exactly where you put it.

Wide Compatibility

Designed for modern high-end GPUs, including NVIDIA GeForce RTX 4090, 4080, 4070 and AMD Radeon RX 7900 XTX, 7900 XT, 7800 XT, as well as any other PCIe x16 device such as SSD adapter cards, capture cards or expansion cards.
