I have been running 4090 with 13900KS (both water cooled with AIO) for 18 months now. Typical power consumption during use is around 70..80W (as measured from the wall). Max I have managed to press for under stress testing is 660W. System’s 850W power supply feels just fine, should have got a smaller one.
