Delivery and Shipping

Add some general information about your delivery and shipping policies.

MWE White offers 80 Plus Standard certification, ing an average efficiency of 80% at typical load. The DC-to-DC + LLC circuit design allows the unit to convert power from a single +12V rail for a reliable, efficient, and safe user experience. The thermally sensitive HDB fan cools based on the temperature, adjusting constantly as the system needs support. Not only does this waste less power but it also creates a quieter overall user experience by not running the fan at maximum noise level when not needed. The MWE White is a great budget option PSU for that computing experience.
