Corsair launches new ThermalProtect 12V-2×6 cables to prevent GPU overheating

Uneven power distribution on 12V‑2×6 connectors has led to overheating concerns for some RTX 5090 buyers, but third‑party cable makers like Corsair are now introducing new safety features to address the issue. Corsair's new ThermalProtect 12V‑2×6 GPU power cable can shut down a graphics card if it detects dangerously high temperatures at the connector.

ThermalProtect adds an additional layer of over‑temperature protection by monitoring the cable 30mm from the GPU plug, with the sensor hardware built into a cable comb to keep the design unobtrusive. If the sensor registers extreme heat, the kind associated with poor seating, uneven pin contact or cable strain, then the system triggers a GPU shutdown to prevent damage.

The first product to use the technology is a standalone 12V‑2×6 cable compatible with any power supply that includes a native 12V‑2×6 output. It requires no configuration and functions as a plug‑and‑play replacement for standard PCIe 5.1 GPU cables. Corsair says the single‑cable design also reduces clutter compared to multi‑plug adapters and includes grey‑tipped connectors to make it easier to confirm a fully seated fit.

The cable features a flexible sleeved design for easier routing and is available in black or white, with a 650mm length to accommodate larger cases. The cable is available now, costing £18.50 on Amazon UK.
