The 80 PLUS Bronze efficiency rating, DC-to-DC + LLC circuit design, single +12V rail, active PFC, and temperature-sensitive fan make this power supply unit true to its original purpose. This PSU will handle all your core computing needs without the hassles or challenges of additional speciality features, software synchronisation, or other bells and whistles. Just plug it into your system and get to work. For a great mid-tier computing experience, you can't go wrong with the MWE Bronze V2.80 PLUS BRONZE CERTIFIEDIt's essential to understand what efficiency is and what the ratings actually mean. The efficiency rating indicates how much power is retained and how much is lost when it is transferred from the wall to your components. It does not reflect the PSU's overall quality. 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.120MM HDB FANThe constant struggle between cooling and noise is as old as the consumer PC industry itself. Keeping your components cool without having to hear about it while you work is still one of the most significant challenges for all fan-based cooling technologies. The MWE Bronze's solution to this problem is a thermally sensitive 120mm HDB fan. It spins based on the system's temperature, constantly adjusting to keep your PSU running smoothly and safely with the minimum amount of noise required.SINGLE +12V RAILGetting power from the wall to the PSU and then to your components is tricky. The power comes in one voltage level, but your components need a different one. That power has to be transferred to/through a converter to make it safe for your parts to use without overloading.The lines/rails used to power the converter from the wall must be reliable and consistent to ensure your system's overall performance. That's why the MWE Bronze only uses one +12V rail for this process. This way, all components in your system are constantly fed the same power from the same source, guaranteeing consistency across all connections.DC-TO-DC CIRCUIT DESIGNPower comes in multiple voltage levels. The wall delivers power at a single voltage level, but you need that voltage level to operate correctly. The process of converting raw power from the wall to the multiple voltage levels your components need requires specialised components to complete it quickly, efficiently, and safely. The MWE Bronze's DC-to-DC + LLC technology was painstakingly crafted to accomplish this goal. The Dual Forward circuit layout has been designed to convert 12V power to 3V and 5V levels with minimal ripple noise, 80 PLUS Bronze efficiency, and reduced risk to your connected components.
