Under the suicide test, the Titanload EX cable maintained hotspot temperatures below 95 degrees Celsius, whereas the standard 12V-2×6 cable surpassed 120 degrees Celsius. Notably, there was only a 5% difference between the Titanload cables.
Citing Arrhenius' equation, which states that the failure rate doubles for every 10 degrees Celsius increase in temperature, the Titanload cable has a thermal failure rate of 6.5%, and the Titanload EX cable, with 1.2%, is under a standard load of 669W, that of the 12V-2×6 cable.
Segotep will incorporate the Titanload cables with the company's forthcoming Titanload power supplies intended for Nvidia's GeForce RTX 50 (codenamed Blackwell) series and subsequent products. Nevertheless, the company has not yet confirmed whether the Titanload cables will be sold separately.
Segotep is not the first brand to try to seek a solution to prevent meltdowns of the 12VHPWR and 12V-2×6 connectors. Numerous companies have endeavored to address this issue. Superficial efforts include coloring the connector to help users ensure correct insertion, while more sophisticated solutions use devices that monitor power usage or provide load balancing . Additionally, the DIY community has proposed innovative workarounds . It remains to be seen whether Segotep's brute-force attempt will have any greater success in preventing failures.

TechieTwo Assuming equal metal resistance, it all boils down to pin contact area. Even solid copper pins with minimal contact area can overheat. As the contacts heat up the electrical resistance increases causing a snowball effect that results in failure. Obviously for 9+ amps the pin contact area should have been increased because you rarely get ideal terminal contact in these push fit connectors. Reply
nimbulan I'm really curious how they're accomplishing this. There's not exactly a lot of space to work with in these tiny connectors to fit more robust terminals inside. Reply
King_V I'm curious at to whether the rest of the Segotep PSU is up to the task. Unless they've changed in the past couple of years, weren't they generally considered a dumpster-fire level of quality? Reply

Just what I was thinking it does not matter how solid the pins are if the contact between socket and pins is poor. Reply
User of Computers how about some load balancing on those pins? Reply
