I'm planning to upgrade my system with a 3080 graphics card alongside my Ryzen 7 5800X, and I currently have a Corsair RM650 Gold power supply. I'm wondering if this 650W PSU will be enough to power my setup without any issues, especially since I'm thinking of overclocking the GPU.

Yes, a 650W will work, but I'd be cautious. You could either undervolt both your CPU and GPU to decrease their power consumption, or consider upgrading to a 750W PSU for better stability.
Make sure your PSU has enough PCIe power cables for the GPU! While 650W might work, it's cutting it close. Ideally, you should have 750W, or even 850W for more headroom. Each cable should ideally run separately, especially for a card that draws over 300W.
You can technically run a 3080 with a 650W PSU, but you might face some challenges. The 30 series GPUs have high power spikes, which could cause your PSU to shut down temporarily to avoid damage. If you have other GPU options, like a 7800 XT or 4070, those might be more suitable for your current PSU setup.
