I'm planning to upgrade my desktop with a new 5070 Ti graphics card, but I'm using an older Seasonic X-850 power supply that has served me well across multiple builds. It's been over 10 years since I got this PSU, and I'm concerned if it still has what it takes to power this new GPU. Seasonic offers a compatible 12VHPWR cable for my PSU, suggesting it can handle the upgrade, but I'm thinking about buying a Cablemod cable instead since the official one is hard to find. Should I keep using my reliable X-850 for this upgrade, or is it time to invest in a new power supply?

I've been using a Seasonic TX Prime 850W PSU with a Cablemod 12VHPWR cable for my setup. It's been running smoothly for about three weeks now. Just so you know, with the right cable, your PSU can safely provide up to 600W if needed, which can be a good option too! That said, it's always better to err on the side of caution when it comes to power supplies.
I wouldn't risk it with a PSU that's over 10 years old, even if it was high-quality when new. I had one fail on me once, and it wrecked another system. I'd recommend getting a new PSU, especially since the 5070 Ti is a power-hungry card. Better safe than sorry, right?
Honestly, after a decade, it's probably time to consider a replacement. PSUs degrade over time, and while they can last, the risk increases as they age. If it's been about 10 years, I'd think about getting a newer model for peace of mind. It's great that you want to keep reliable components, but don't push your luck with such an expensive GPU. If your PSU fails, it might take other components with it!
