Pros & Cons

Pros

✓ Zero RPM fan mode keeps the PSU silent at low and medium loads
✓ 80 PLUS Gold certified for less waste heat and lower running costs
✓ 100% Japanese 105C capacitors rated for multi-build service life
✓ Ten-year CORSAIR warranty spans several system rebuilds
✓ Fully modular white paracord cables suit white-themed builds

Cons

✗ 750W ceiling is tight for a 4090/5090 plus high-core-count CPU
✗ White cables and housing clash with black or RGB-neutral builds
✗ Modular design means unused cables still need storage somewhere
✗ Fan stays off under light loads, so airflow-dependent cases get no PSU assist
