Pros & Cons

Pros

✓ ATX 3.1 with 12V-2x6 connector delivers up to 600W to RTX 40 Series cards
✓ 80 PLUS Gold plus Cybenetics Gold certified for efficient power draw
✓ 135mm fluid dynamic bearing fan stays silent under 50% load via Zero Fan Mode
✓ Fully modular cables cut clutter and improve case airflow routing
✓ 100% Japanese capacitors for low ripple noise and longer hold-up time

Cons

✗ 1000W is overkill for mid-range or single mid-tier GPU builds
✗ Fan spins up past 50% load, so not silent under heavy gaming
✗ Cybenetics A noise rating sits below the quietest A+ supplies
✗ Single 12V-2x6 connector limits high-draw multi-GPU setups
