Overview

The Thermaltake AC-077-CO6OTN-C1 is a PCIe 4.0 x16 riser cable engineered for vertical GPU mounting in desktop PCs. Its defining design choice is the dual 90-degree connectors — both the motherboard-side male and the GPU-side female plugs are right-angled, which allows the cable to lie flat against components and case panels rather than protruding outward. This reduces mechanical stress on the connectors and makes for a much cleaner installation compared to straight riser cables, especially in cases where space between the motherboard and the side panel is limited.

At 400mm in length, the cable provides enough reach for most mid-tower and full-tower vertical mount kits. It supports the full PCIe 4.0 data rate of 16Gbps per lane across all 16 lanes, so there is no bandwidth bottleneck between your GPU and motherboard. The cable's EMI shielding — constructed from aluminum foil Mylar over tinned copper wire — helps maintain signal integrity at these high data rates. The white thermoplastic elastomer jacket gives it a clean look for white-themed builds, and Thermaltake backs the cable with a three-year warranty.

Frequently Asked Questions

The dual 90-degree connectors allow both ends of the cable to sit flush against the motherboard and GPU bracket, reducing cable bend stress and enabling cleaner routing in tight vertical GPU mount setups.
Yes, PCIe is backward compatible, so the cable works with PCIe 3.0 systems. However, it will operate at the PCIe 3.0 data rate rather than the full 16Gbps PCIe 4.0 speed.
The 400mm (15.8-inch) length accommodates most mid-tower and full-tower vertical GPU mounting brackets, but you should verify clearance in your specific case before purchasing.
No drivers are needed. However, some motherboards may require you to change the PCIe slot setting from Auto to Gen 4 or Gen 3 in the BIOS for stable operation with a riser cable.
The aluminum foil Mylar EMI shielding reduces electromagnetic interference that can cause signal degradation, helping maintain a stable 16Gbps connection at full PCIe 4.0 bandwidth.
