👎 Cons
- While 650W is sufficient for many systems, it may be insufficient for high-end PCs with multiple power-hungry GPUs or extreme overclocking.
- The Zero RPM Fan Mode might temporarily disengage the fan, which could lead to slightly higher internal temperatures before the fan kicks in.
- Being fully modular requires careful cable connection, and some users might find it slightly more complex than non-modular designs with pre-attached essential cables.
- The 80 PLUS Gold certification is excellent, but higher tiers like Platinum or Titanium exist for even greater energy efficiency.
- The power supply's physical dimensions are not provided, which could be a concern for very compact PC cases.
