Is my PSU compatible with RTX 4080?

๐ŸŸก Yes, but...

NVIDIA recommends 750W. 650W may work for efficient builds. Check 12VHPWR connector.

โš ๏ธ Low Confidence
๐Ÿ“Š Why this confidence level?
  • RTX 4080 draws 320W TDP.
  • Most 750W PSUs handle it fine.
  • The card needs a 12VHPWR connector or adapter.
  • Native ATX 3.0 PSUs are ideal but adapters work with quality 8-pin cables.
