'Where is Nvidia? Call Nvidia, guys': Meltgate be damned, modders discover RTX 5090 can use 8-pin connectors…
Modders have successfully adapted a GeForce RTX 5090 to use standard 8-pin power connectors instead of the newer 12V-2x6 standard, which has been associated with melting issues on the RTX 4090. The modded RTX 5090 demonstrated stable performance and cooler temperatures than the 12VHPWR connector, even when pushed beyond its rated specifications, leading to calls for Nvidia to reconsider its power connector choices.
Nvidia GPUs can't stop finding new things to melt
High-end Nvidia GPUs, including the RTX 4090, RTX 5090, and RTX 5080, continue to experience issues with melting power connectors, even with revised designs and specialized adapters like the Corsair PCIe 5.0 12V-2×6. This ongoing problem, also affecting some AMD cards, is largely attributed to uneven power delivery through the conductors, leading to excessive heat buildup. While Nvidia and Corsair have initiated RMA processes for affected users, the fundamental issue with the 12VHPWR connector standard persists.
Possibly the first instance of Asus' anti-melting 12V-2×6 power cable…err…melting shows up, adding more fuel to the fire that is Nvidia's connector
A new instance of an Asus ROG Equalizer power cable, designed to prevent melting issues with Nvidia graphics cards, has reportedly melted. While the exact cause is unknown, this incident adds to ongoing concerns about Nvidia's 12VHPWR and 12V-2x6 connectors, which have been linked to melting due to power delivery imbalances. The article discusses potential solutions and user advice for mitigating these risks.
Nvidia GeForce RTX 4090 owner saved by their cat, after GPU power connector melts
An owner of an Nvidia GeForce RTX 4090 graphics card reported their cat alerted them to a melting power connector, potentially preventing a PC fire. This incident adds to documented cases of high-end Nvidia GPUs experiencing issues with their power connectors, particularly the 12VHPWR type, due to high power draw. While precautions like secure connections and good ventilation can help mitigate risks, the problem persists with powerful cards like the RTX 4090 and RTX 5090.
