Something to look forward to: A hardware modder has shared a promising fix for Nvidia's RTX 5090, a GPU with a documented history of power-related issues. Best yet, the workaround is said to be "relatively affordable" and would even come with a warranty.

Over on Reddit, user DallasGrave outlined the approach taken when developing the mod. In short, the fix utilizes a pickup PCB soldered to the contacts of the original 12VHPWR header that feeds an auxiliary dual eight-pin board. This effectively spreads the load across three sets of cables, which significantly reduces power draw and temperature.
