At a Glance
Solid Baseline Performance
With 450W, the power supply is suitable for basic PC systems, though it offers limited headroom for power-hungry graphics cards.
Average Efficiency
The 80 PLUS Bronze certification ensures decent energy efficiency, but it falls short of higher standards such as Gold.
Non-Modular Cables
As the cables are fixed, unused ones cannot be detached, which makes cable management inside the case more difficult.
