What Buyers Say
Users frequently highlight how quiet this power supply runs, often noting it's nearly inaudible even under load, which is a big win for noise-sensitive setups. The fully modular design gets praise for making builds cleaner and easier to manage. The inclusion of a native 12V-2x6 cable for modern GPUs is also a recurring positive point. However, some builders have mentioned that the cables are a bit stiff, which can make routing them neatly a bit of a struggle.
“Needed a PSU for my new RTX 4070 build, this thing is SO quiet I thought it wasn't even on at first, but man, those cables are a pain to bend around my case, almost broke my fingers. Still, 10 years warranty is sick.”
Common Praise
- Operates very quietly, often described as nearly inaudible during use.
- Fully modular design simplifies cable management and improves PC case airflow.
- Includes a native 12V-2x6 connector, ready for current-generation graphics cards.
- High efficiency ratings (80 PLUS Gold, Cybenetics Platinum) are appreciated for energy savings.
- The 10-year warranty provides significant peace of mind.
Common Complaints
- Cables are reported to be stiff, making them difficult to bend and route in some cases.
- The 'Not compatible with all built-in computers or systems' warning is vague and requires extra research from buyers.
