Thermaltake PCI-E 4.0 Dual 90° Riser Cable – 400 mm, PCIe 4.0 x16 High-Speed Flat Extension with EMI Shielding

The Thermaltake PCI-E 4.0 Dual 90° Riser Cable at 400 mm (P/N AC-077-CO1OTN-C1) is engineered for next-generation custom PCs where GPU placement, aesthetics and signal integrity all matter. Whether building a high-end gaming rig with a vertically mounted graphics card or a creator workstation needing clean cable routing behind glass panels, this riser cable delivers.

At its core, the cable supports PCIe 4.0 x16 speeds, enabling full-bandwidth transmission up to 16 Gbps and compatible with older standards too. The dual 90-degree connector design allows the cable to lay flat against the motherboard tray, making it perfect for builds with limited clearance or showcasing GPUs vertically without bulky cable loops. With a 400 mm length, there’s enough reach to accommodate most mid-tower and full-tower layouts, letting you route cleanly while minimizing excess slack.

Signal integrity is a major concern for riser cables — this model includes an EMI shielding cover, thermoplastic and foil shield materials, and undergoes rigorous high-frequency testing to ensure minimal signal loss.  The build materials (thermoplastic, PCB S1000-2M, polyethylene (PE), tinned copper and aluminum-foil Mylar) ensure durability and stable performance even under stress

For system builders focused on aesthetics, the black version blends into dark-themed builds or hides behind panels; there’s also a Snow/white edition for lighter-tone builds.  Whether you're aligning a vertically mounted RTX-40xx/50xx series GPU, routing through a custom water-cooling chassis, or creating a clean builder-grade layout behind a glass panel, this riser cable delivers both performance and visual polish.

In short: the Thermaltake PCI-E 4.0 Dual 90° Riser Cable 400 mm is a premium choice for enthusiasts who care about both form and function — offering high-speed GPU connectivity, flexible routing and a clean presentation.
