So, is a 650W PSU enough? If you are eyeing a mid-range to upper-mid-range build, maxing out around an RTX 4070 Super or an RX 7700 XT—the answer is a resounding yes. Leaving that extra headroom means your power supply runs cooler, stays quieter, and lasts much longer. Instead of blowing your budget on a mediocre 850W unit just for a bigger number, you are far better off investing that money into a premium, top-tier 650W power supply. Happy building!
