I'm currently running an RTX 2070 paired with a Ryzen 5600X for 1440p gaming, but I'm hitting VRAM limits, so I'm considering upgrading to an AMD 9070XT, which is priced around £600 and seems like the best value right now in the UK. My current power supply is a 2017 Corsair TX750M with only two daisy-chain PCIe 8-pin connectors, while some of the new cards require three. Is it safe to daisy-chain an additional connector for power, or should I just go ahead and replace the PSU altogether?

As for my experience, even with an older system running a 6080 XT on a 750W PSU, I never ran into issues. Just make sure you keep an eye on the temperatures and performance.
Using a pigtail for the third connector should work fine, but I'm skeptical if 750W will be enough, especially for an overclocked card. Undervolting may help if you have issues, but just be cautious with your power draw.
Given your PSU's age, upgrading it might be a good idea. A newer model with 850W capacity would offer better stability and efficiency, especially since you mentioned it’s from 2017.
For sure. My old PSU lasted over 15 years, but I'd still recommend getting a new one to be safe.
Definitely check the strength of the 12V rail on your PSU. If it's 300W per rail, swapping it out is wise. The RTX 2070 pulls around 200W, so the 9070XT's 300W draw means you want that extra margin just to be safe.
That's true! The TX750M is showing its age. An 850W upgrade could help with future-proofing too!
