A 1000W power supply is sufficient for this system as configured, including the RTX 5090 and Ryzen 9 9950X3D. That said, some users prefer higher wattage (such as 1200W) for additional headroom, especially if planning future upgrades or sustained heavy workloads. The power supply is upgradeable, as this is a standard desktop system. If you want additional headroom, you can replace it with a higher wattage unit as long as it fits the case and uses compatible connectors.
