Cybenetics Labs has revealed a prototype ‘anti-melt’ cable, aiming to resolve the known reliability concerns associated with the 12VHPWR/12V-2×6 power standard. This cable incorporates direct, proactive monitoring, offering a safeguard for users seeking to avoid potential melting or burning risks often linked to high-end graphics cards such as the RTX 5090.
As reported by ComputerBase, the prototype functions as a native 12V-2×6-to-12V-2×6 cable, featuring a compact, low-profile inline box. This box houses the monitoring electronics and a status LED, designed to avoid the bulk of larger components that might interfere with air coolers or tight case configurations. Its flexible design ensures compatibility with most Founders Edition and custom AIB layouts without obstructing shrouds or requiring awkward mounting.
Operationally, the cable acts as an active circuit breaker, continuously monitoring current and temperatures at both the graphics card and power supply connections. A USB-C port is included solely for data logging and configuration purposes. The integrated safety features, which include a high-pitched buzzer and an emergency power-cut function, operate entirely autonomously. Once specific thresholds are set via software, the USB connection can be removed, and the cable will maintain its protective profile independently.
The cable is engineered to differentiate between harmless, momentary power spikes and hazardous, sustained thermal runaway conditions. Users can customize thresholds for parameters such as ‘Over Current Trigger’ (defaulting to 8-12 A) and ‘Over Temperature Trigger’ (defaulting to 80-95°C). A dual-stage warning system is also in place: if a limit is exceeded, a buzzer activates for a configurable duration (default 10 seconds). Should the condition persist, the cable will cut power to the GPU. When connected via USB, the accompanying software provides updates every 100 ms, enabling users to export thermal and current data for detailed stability analysis.
The cable’s market availability remains uncertain, as Cybenetics has not yet secured a mass-market distribution partner. The company has expressed an intention to sell the cable ‘close to cost,’ prioritizing the enhancement of PC ecosystem safety over profit. Currently, the cable necessitates a native 12V-2×6 output from the power supply. However, a version compatible with dual 8-pin connectors for older power supplies is technically feasible if the project proceeds to production.
