I'm currently using a Ryzen 3600 and RX 5600 XT setup, but planning to upgrade to a Ryzen 5700X and RX 7800 XT. I overlooked the PSU requirements and found that my current Seasonic Focus 650W Gold PSU is 50W below the recommended specs from AMD. Should I stick with this PSU, or do I really need to upgrade to a 750W or 850W model? Any advice would be appreciated!

According to some reviews, the 650W should handle your setup, but I recommend considering a 750W PSU that meets ATX 3.0 standards for better efficiency. If you're outside the US, finding a reliable PSU might be a bit tricky. I’ve seen some decent options like a B-rated 750W unit on tier lists which should serve you well. Here's a good deal for an 850W Gold PSU that's competitively priced: [PCPartPicker List](https://pcpartpicker.com/list/kx2cNz).
You're probably good with the 650W PSU since it's more than double the combined max load of your CPU and GPU. However, for peace of mind and to handle potential power spikes, you might want to consider upgrading to a higher wattage PSU, maybe even a 1000W for future-proofing. Better safe than sorry!
I think the 650W should be just fine for your setup. A lot of times, AMD and Nvidia provide conservative wattage requirements, and they don't account for quality PSUs. Since you have a reputable brand like Seasonic, I believe you're covered. Just to be sure, check out this wattage estimator at PCPartPicker to confirm: [pcpartpicker.com/list](https://pcpartpicker.com/list). Save your money for now!
Thanks! I think I’ll test the CPU and GPU when they arrive first, and save up for a higher wattage PSU if needed. Unfortunately, I’m not in the US, and the best option here is a DeepCool PN850M which is rated B on the tier list.
