The MWE White offers a simple, reliable way to power your system safely and efficiently at a low cost. The 80 PLUS 550W white efficiency rating, DC-to-DC + LLC circuit design, single +12V rail, active PFC and temperature-sensitive HDB fan offer a power supply unit that stays true to its original purpose. This PSU will handle all your core computing needs with none of the hassles or challenges of additional special features, software synchronization or other bells and whistles. Just plug it into your system and get to work. For a great core computing experience, you can't go wrong with the MWE White. The 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 your work is still one of the greatest challenges for all fan based cooling technologies. The MWE White'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. Power comes in multiple voltage levels. The wall delivers power in one voltage level but your components each need a specific voltage to operate properly. The process of converting raw power from the wall to the multiple voltage levels your components need requires special components to complete this process quickly, efficiently and safely. The MWE White'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 efficiency and reduced risk to your connected components. For many PC Builders with aesthetics in mind, cabling can be on of the most troublesome parts of assembling a PC. Cables can be confusing, too short or too long and they almost never look good. The MWE White uses flat and flexible black cables to help deal with these problems.
