Nvidia DLSS 5 power draw hits 647W as power connector runs hotter than the GPU die, upscales frame rates and flame temps on 16-pin
QuasarZone tests show the 16-pin power connector on a GeForce RTX 5090 reaches temperatures above 90 degrees Celsius at peak power consumption near 650W.
The GeForce RTX 5090 graphics card, capable of leveraging Nvidia's DLSS 5 technology, has shown significant increases in power draw and temperature when this feature is enabled. Korean outlet QuasarZone tested the GPU, finding that when DLSS 5 was turned off, the 16-pin power connector temperature ranged from 77.1°C to 83.4°C. With DLSS 5 enabled, these temperatures rose to 83.4°C to 91.7°C, indicating the hottest point on the graphics card.
In contrast, the Asus ROG Astral GeForce RTX 5090 and GeForce RTX 5080 Founders Edition had lower temperatures when DLSS 5 was active. Power consumption also saw a notable increase, with the GeForce RTX 5090 consuming 13% more power with DLSS 5 enabled, while the GeForce RTX 5080 saw a 17% increase. Despite these rises, both cards operated within their official TDP specifications.
QuasarZone's findings reveal that the 16-pin power connector is the primary hotspot for temperature and power draw, with a potential risk of failure if not properly connected.
