“I currently run a 4090 with a 1000W power supply. The specs for the 5090 show a 1000W minimum PSU required. Will it actually be enough? The 4090 uses 45 Watts when it is at 0% utilized. I am guessing that the 5090 will use close to 90W at its low end.”

1000W IS ENOUGH!
Sorry, there was a problem. Please try again later.I'd plan on getting a 1200W PSU, but you'd still get a lot out of the card with 1000 watts.
Sorry, there was a problem. Please try again later.Actually, 1000w is enough. It's been used in other test systems and in pre-built system pre-orders from reputable builders. The card will draw what it wants, it's not going to run better with a 1200w power supply. If it tried to pull too much, your game would crash or you'd get a blue screen and power kernel error in your system event viewer log.
Sorry, there was a problem. Please try again later.While the 5090 is a much stronger gpu, it's power optimization is also just as advanced compared to the 4090, so the 1000 minimum makes sense.
Sorry, there was a problem. Please try again later.No. 1000 watts is not enough. And you never want to run a power supply at max power. go to pars picker and add all your pc components , it will calculate your wattage.
