Is an 850W power supply enough for an RTX 4090?

๐ŸŸก Yes, but...

Barely. NVIDIA recommends 850W minimum, but 1000W+ is safer for high-end CPUs and overclocking.

โš ๏ธ Low Confidence
๐Ÿ“Š Why this confidence level?
  • An RTX 4090 draws 450W TDP with spikes up to 600W.
  • Combined with a power-hungry CPU (i9/Ryzen 9), 850W leaves little headroom.
  • For peace of mind, get a 1000W or 1200W PSU, preferably ATX 3.0.
