This article covers Thermaltake PCI-E 4.0 Dual 90 Degree Riser Cable 400mm Black AC-077-CO1OTN-C1 CS9123.

Overview

The Thermaltake PCI-E 4.0 Dual 90 Degree Riser Cable 400mm Black (model AC-077-CO1OTN-C1) is a high-quality PCIe riser cable designed for vertical GPU mounting. It supports up to 16 Gbps data transfer, fully utilizing PCIe 4.0 x16 bandwidth. With a compact 400mm length and dual 90-degree connectors, it is ideal for tight spaces while maintaining clean cable routing. The cable also features EMI shielding for stable signal integrity.

Connectivity & Compatibility

The riser cable uses a PCI Express x16 connector and is compatible with both PCIe 3.0 and 4.0 motherboards from Intel and AMD. The dual 90-degree design allows the cable to run parallel to the board, minimizing bending stress and improving airflow. Thanks to EMI shielding, high-speed data transmission remains reliable even in electrically noisy environments.

Product Info

Released in late 2024, this riser cable is positioned as a mid-to-high-end PC building accessory. Pricing is around ¥8,566 (approximately $58 USD) on major Japanese retailers. The package includes only the cable itself; no mounting bracket is included. Thermaltake recommends using this cable with their vertical GPU mount kits for best results. While it supports PCIe 4.0, it also works seamlessly with PCIe 3.0 systems, making it a future-proof choice.

Best Use Cases

  • Enthusiasts building show PCs: For those who want to showcase a vertical GPU with tempered glass side panels. The dual 90-degree connectors keep the cable flat and tidy. Note: your case must support vertical GPU mounting. - Users with heavy graphics cards: Large GPUs can stress the motherboard slot. A riser cable lets you mount the GPU securely elsewhere, reducing long-term wear. - High-performance systems: Ideal for gaming or workstation builds using PCIe 4.0 GPUs like the RTX 40 series or RX 7000 series. The cable ensures no bottleneck in bandwidth. Budget builds can also benefit from the future-proofing.
