As the 12VHPWR power connector and its 12V-2x6 successor continue to plague the best graphics cards with meltdowns, Segotep, a Chinese manufacturer of computer hardware, believes it has a potential solution. The company's latest Titanload 12V-2x6 power cables (via Uniko's Hardware) incorporate power pins with higher current ratings, which could serve to prevent such connector failures.
PCI-SIG and Intel's ATX 3.0 specifications mandate a minimum electrical current rating of 9.2A for the power pins within the 16-pin power connector. Segotep's Titanload and Titanload EX power cables employ 12A and 14A power pins, respectively. These ratings deliver safety margins that are 30% and 52% higher than the reference specification. Additional advantages of employing higher-amperage pins include enhanced heat dissipation and improved capacity to contain current imbalances during spikes.

Segotep performed a standard test under ambient conditions at a temperature of 26 degrees Celsius, without the use of air cooling, with a load of 669W at 9.3A. The company subsequently increased the load to 864W at 12A for an extreme test, and further to 1,080W at 15A for a suicide test.
The basic Titanload cable produced a 43% reduction in average temperature and a 48% reduction in peak temperature compared to a standard 12V-2x6 cable. Additionally, the hot spot was 38% cooler.
Meanwhile, the results for the Titanload EX cable, designed for overclockers, were even more remarkable. The average and peak temperatures decreased by 67% and 72%, respectively, and the hot spot dropped by 53%.

Logically, no results were provided for a standard 12V-2x6 power connector during the extreme test, as the power load significantly exceeds the specified limits. Although a direct comparison was not feasible, Segotep did compare the Titanload and the Titanload EX, with the latter clearly having the advantage due to its pins possessing higher current ratings.
The Titanload cable demonstrated temperatures below 75 degrees Celsius, whereas the Titanload EX cable's temperatures remained significantly lower, well below 50 degrees Celsius. The observed temperature difference approximates up to 38% lower temperatures for the Titanload EX. Regarding the hot spot, the Titanload cable nearly reached 100 degrees Celsius, while the Titanload EX cable remained below 75 degrees Celsius, representing an approximate 27% reduction in temperature.
