Nvidia say that they consider the RTX 4090's melting power adapter problem to be long fixed, and it shouldn't reappear on the upcoming RTX 5090 and RTX 5080.

Nvidia's GeForce RTX 5090 starts at $1,999 before you factor in upsells from the company's partners or price increases driven by scalpers and/or genuine demand. It costs more than my entire gaming PC.

Not only does the VRAM jump up from 24GB to 32GB in the RTX 5090, but it gets a lot faster too with GDDR7 memory. You’re getting both more of it and a faster speed at 32 Gbps.
