At a Glance
Solid base performance
With 550W, the power supply is suitable for basic PC systems, but offers limited headroom for power-hungry graphics cards.
Average efficiency
The 80+ Bronze certification ensures decent energy efficiency, though it falls short of higher standards like Gold.
Non-modular cables
As the cables are fixed, unused wires cannot be detached, which makes cable management inside the chassis more difficult.
