500W? That's an absurd amount of heat. I suppose they don't make 75W GPUs anymore (I'll replace my 1050Ti when they do), but still...
You can get the 1650 that runs with 75W. There's even a passive model out there, the Palit KalmX. I refuse to buy a GPU with extra power connectors.
The difference between these two is rather small, despite 4 years difference. 1050Ti delivers about 2TFlops, 1650 about 2.6 TFlops. Other specs (VRAM bandwidth, fillrate) are pretty close as well.
Generally, I only upgrade components when I can get at least 2x improvement.
