Dimension Scores
The 80 PLUS Gold and Cybenetics Platinum certifications, alongside ATX 3.1 readiness, indicate very high energy efficiency and robust power delivery.
The Cybenetics LAMBDA A+ acoustic certification and iCool Intelligent Fan Control Mode, which keeps the fan off at low loads, point to very quiet operation.
The use of 100% Japanese Capacitors and a 10-year warranty suggest a high standard of component quality and durability.
Its fully modular design allows for connecting only the necessary cables, significantly improving internal airflow and case aesthetics.
Best For
- Mainstream PC builds needing 650 watts of power with an emphasis on energy efficiency.
- Users who value a quiet PC, especially during light tasks or web browsing.
- PC builders planning to use ATX 3.1 compatible components.
- Anyone building a white-themed PC, given the availability of white cables.
Not Recommended For
- High-end systems with power-hungry GPUs and CPUs that exceed 650 watts.
- Users in areas prone to frequent power fluctuations or brownouts, due to reported concerns about its performance in such conditions.
Watch Out For
