  • Did a power calculation and it was about 650W for the whole PC. Don't really like being that close to the full output power. Don't know if it's still true but I was always told PSU's ran happiest at about 50% load.

  • But those calculators already consider absolute theoretical peak power with a safety margin. It would be running at a fraction of 650 W most of the time.

    What would be the average power?

  • It's also straightforward to power-limit the RTX 40-series GPUs and cap the maximum wattage without losing much peak performance at all.

    With an RTX 4090 GPU set to a 60% power limit and a modern high-end consumer CPU capped at ~100W TDP, you can easily run an entire RTX 4090 system with a decent 500W PSU and only lose ~8% peak GPU performance.
