I'm considering replacing my current gaming PC—an RTX 3090, Core i7-10700K, Z490 motherboard, and 32 GB of RAM—with an RTX 5090 Astral, Ryzen 9 9950X3D, ASUS X870 motherboard, and 64 GB of RAM. My main use is gaming, and my current system is beginning to struggle in newer titles. I've been saving for this upgrade for several years, but I'm concerned about reports of RTX 5090 power connectors or adapters melting, especially since products are difficult to return where I live. I've also noticed prices rising quickly, so I'm unsure whether to buy now or wait. Has anyone using the Astral model experienced these issues, and would a less expensive GPU or a partial upgrade make more sense?

For gaming alone, a 5090 is probably excessive unless you’re playing at very high resolution with demanding ray tracing or want extremely high refresh rates. A 5080 or even a 4090 could offer a much better balance between performance and cost. You may not need to replace every part at once either—depending on your resolution and games, upgrading the GPU first could extend the life of your current system.
The melting reports generally involve a poorly seated 12V-2x6/12VHPWR connection, excessive bending near the plug, or using an unsuitable adapter. The Astral card’s per-pin sensing can help identify an uneven connection, but it does not eliminate the need to install the cable correctly. Use a proper dedicated cable from a reputable power supply, push the connector in fully until it is completely seated, and avoid sharply bending it near the socket. Since returns are difficult where you live, buying from a store with strong warranty support is especially important.
That connector issue is my biggest concern because I may only be able to exchange the card rather than get a refund. None of my friends own one, so I’m hesitant to take the risk without more firsthand experience.
Before committing to the full platform upgrade, check whether the games you play are actually limited by your 3090, your 10700K, or something else. At 4K, the GPU is usually the main limit, so replacing the graphics card first may be enough. At lower resolutions or very high refresh rates, the CPU upgrade could help more. Compare current frame rates and frametime behavior before spending on a new motherboard, processor, memory kit, and graphics card together.
At the prices being reported, the 5090 is approaching the cost of a used car in some regions. Waiting may be the safer choice if your current PC is still usable, since launch shortages and inflated pricing may settle. A future refresh could also provide better value, although there’s no guarantee of when that would happen.
I mostly play games, and newer releases are starting to push my current build hard. I’ve saved for this upgrade for years, but I’m trying to understand the connector risks before spending that much.
