What happened
Corsair's RM1000e (2026) PSU includes a ThermalProtect feature: a temperature-sensing 12V-2x6 cable that shuts the GPU down before the connector can melt. The unit is built by HEC, offers Platinum-class efficiency, and has a 500W fanless operating window.
Why it matters
If you're assembling local AI workstations with high-wattage GPUs (e.g., RTX 4090/5090-class), the 12V-2x6 connector melting risk is real and costly. A PSU that proactively cuts power via temperature sensing at the connector is a concrete safety feature to prioritize when speccing rigs — but this is one product review, not proof the broader market has solved the problem.
Discussion angle
For builders running local GPU inference or training rigs in Malaysia's warm climate, is connector-level thermal protection now a must-have spec, or is proper cable seating still the real fix?
