Pros & Cons

Pros

  • ✓ Intel ATX 3.1 certified for modern transient power spikes
  • ✓ 80 PLUS Gold efficiency keeps heat and draw down under load
  • ✓ Fully modular cabling, so unused leads stay out of the case

Cons

  • ✗ 750W ceiling is tight for a 4090/5090-class build
  • ✗ Listed under retro-gpus, but it is a modern ATX 3.1 unit, not period-correct
  • ✗ Warranty length is not stated in the listing, so verify before buying
  • ✗ Standard ATX depth may crowd small-form-factor and SFX-spec cases
