Product rating
Information
- •This is THE standard size of a power supply that fits 90% of cases except mini cases. If you don't want to think too much, go with this, it's the most classic.
Pros
- •Very reputable brand for its power supplies. We have personally never had any issues with it, the quality of materials and noise are perfect. Highly recommended!
Cons
- •If you have a low budget, the 'Bronze' and 'Silver' certifications are viable options. However, we recommend at least going for a 'Gold' certification because the power supply is one of the important pillars of your PC and should not be neglected!
