COOLER MASTER BRONZE 650W 230V

It’s important to understand what efficiency is and what the ratings actually mean. The efficiency rating indicates how much power is retained and/or lost when transferring it from the wall to your components. It does not indicate the overall quality of the PSU. A PSU doesn’t need an 80 PLUS Gold rating to be safe and reliable. And a PSU with an 80 PLUS Gold rating isn’t necessarily either of those things. The MWE Bronze V2 guarantees a typical efficiency of 85% while being both safe and reliable.
