Asus built a cable to stop Nvidia's connectors from melting. One has reportedly melted.
A photo posted to Chinese hardware forum ChipHell shows a heavily burned Asus ROG Equalizer cable, with three of its six power pins scorched and visible melting in the plastic housing of one. The ROG Equalizer launched roughly two months ago as Asus' marketed answer to the multi-year saga of igniting 12VHPWR and 12V-2x6 connectors. Critical context is missing: no details on which GPU or power supply was involved, and the incident could be user error or staged for attention. But the cable's core limitation - flagged by hardware analyst der8auer at launch - is that it has no active mechanism to prevent current imbalance across pins, which is the actual cause of melting.
The 12VHPWR connector, introduced with RTX 40-series cards, fails when one pin draws disproportionate current, pushing load past the 8.33A per-pin design limit and generating destructive heat. A class action lawsuit over RTX 4090 connector failures was filed in 2022, the subsequent 12V-2x6 redesign didn't address the root problem, and RTX 5090s now sell for over $4,000. The financial logic behind inaction is bleak: hardware vendors set aside warranty replacement budgets each year, and until melt-related claims consistently blow past those budgets, there's little economic pressure to implement a real fix - like active per-pin current monitoring - that would eat into margins.
Until GPUs and power supplies can dynamically balance per-pin current draw as standard, the connector melting problem will keep producing headlines - and the aftermarket cables sold to patch it will keep proving the point.
