I recently upgraded to a Zotac 5070 Ti 16GB after using a 4070, and I'm a bit concerned about my power supply. I have a Gigabyte P650B with only one cable for the GPU, which splits into two 8-pin connectors. I read that my cables might not handle the GPU's power needs well, potentially only rated for around 225W instead of the 300W the GPU might require. Just to give you more context, here are the rest of my specs: Ryzen 5 5800X3D, Thermalright Phantom Spirit Evo 120 cooler, 32GB RAM, and an MSI MPG B550 Gaming Plus motherboard. I game at 1440p with high graphics settings. I'm looking for some advice or experiences if anyone's been in a similar situation. Thanks!

Your PSU is kind of sketchy. While it might technically work, it's an older model and not rated for the GPU's demands. Just get a good 750W or higher one to avoid any issues. Better safe than sorry!
Exactly! It's not worth the headache; an upgrade will save you trouble later.
I suggest investing in a solid 750-850W PSU. One with a native 12V-2x6 connector will give you peace of mind and ensure your components work properly, unlike your current setup which sounds dubious.
Totally agree! The right power supply can make a huge difference in stability.
For sure! You don't want to risk frying any expensive parts.
I really wouldn't go for it. While a 650W PSU can work, using a split cable with a 5070 Ti feels like a bad idea. It's just not worth the risk of damaging your new card.
Honestly, it sounds risky to stick with that PSU. I'd recommend upgrading to at least a 750W unit. It's better to be safe, especially when running high-end components like your GPU.
I upgraded to an 850W PSU after a similar situation and it made all the difference. I wouldn't risk using a 650W for such a powerful card.
Yeah, I had a similar experience where an old PSU caused major problems.
