I'm considering using a Seasonic Focus GX-650 80+ GOLD power supply for my PC build, which includes an NVIDIA RTX 3070 graphics card, a Ryzen 7800X3D CPU, and an ASUS ROG Strix B650-A Gaming WiFi motherboard. I found the PSU at a great price locally, but I'm wondering if 650W is sufficient for my setup, especially since I've seen recommendations for higher wattage PSU. Any insights would be appreciated!

I would recommend going for at least a 750W PSU for that setup. It gives you a little more headroom, especially for future upgrades or if you decide to overclock.
According to NVIDIA, 650W is the bare minimum for a 3070. It will work, but you might get better performance and efficiency with something around 750W. If you can afford it, I’d say that’s a safer bet!
I'm leaning toward the 650 since it's almost free, but the 750 would cost me over $110. Seems like a tough call!
Yeah, I hear you! I think I’ll just go for the 650 then since it’s cheaper.

I did some digging, and a 650W PSU should handle my EVGA XC3 Ultra and the 7800X3D just fine without stressing it too much, according to the specs.
