Buying a PSU that's too big is generally not harmful, though it might be unnecessary and costlier. While it won't damage your components, an overly large PSU won't be as energy-efficient at lower loads, leading to both higher electricity bills and initial expenses. It's best to match your PSU size to your system's power requirements for optimal performance and cost-effectiveness.

FAQs & Answers
