NVIDIA's GeForce RTX 3090 Ti graphics card is without a doubt the most power-hungry graphics card ever launched, sipping over 500 Watts of power and requiring insanely massive GPU cooling solutions to keep the heat in check. But at the same time, it can be tuned to become an efficiency monster in the high-end graphics card segment.

The NVIDIA GeForce RTX 3090 Ti has a reference TGP of 450W and most custom models are close to or over 500W. The graphics card is supplemented such high amounts of power through the new PCIe Gen 5 16-pin connector which is to accommodate TGP requirements of future graphics cards that would consume up to 600 Watts of power.
