Pros & Cons
👍 Pros
- Single +12V rail design delivers stable power for demanding modern graphics cards.
- Japanese main capacitors provide reliable performance and longer component life.
- 120mm hydraulic bearing fan operates quietly while maintaining effective airflow.
- Multiple built-in protections guard against power surges, overvoltage, and short circuits.
- Wide input voltage range of 100V–240V supports use in different countries without a switch.
👎 Cons
- Non-modular cable design means unused cables must be tucked away, complicating cable management.
- Two PCI-E connectors may limit compatibility with high-end graphics cards requiring three or more power cables.
- 650W may be insufficient for the most power-hungry GPU and CPU combinations.
- No 80+ Gold or higher certification, so efficiency is lower than premium-tier power supplies.
