I'm curious about the longevity of a 650W power supply unit (PSU) for future setups. The specific model I'm looking at features two 8-pin connectors, and I'm considering it for use with an RX 7900 GRE, which also has two 8-pin power inputs. However, I've seen that the recommended PSU for this GPU is 750W. What are your thoughts on whether a 650W unit will be sufficient going forward?

If you plan on upgrading to more powerful GPUs later, a 650W PSU may not cut it. Thankfully, PSU prices seem stable for the moment, but it’s always a good idea to consider future-proofing your power supply.
If you're sticking with decent mid-range GPUs, a 650W unit should last you a while, especially if it's ATX 3.0 rated or good at handling power spikes. Higher-end GPUs tend to eat power like crazy, though, so you might want to think twice if you're going super high-end.
A 650W PSU might be enough for now, but it really depends on your overall build and how efficient the PSU is. For your RX 7900 GRE setup, it's a bit of a gamble since it has high power demands along with your other components. Just keep an eye on the total wattage you'll need!
Yeah, I agree! It's better to have some headroom.
