be quiet! are a name KitGuru consider synonymous with quality. Today we look at their latest Dark Power Pro 11 550W unit – a new lower capacity model set to supplement the 850W, 1000W and 1200W units released in May this year. The 850W model earned our highest award back in May so we have high hopes for this 550W unit.

All of these supplies are modular designs and feature 80 Plus Platinum efficiency (up to 94 percent). be quiet! have been able to achieve such high efficiency levels due to the new Half Bridge + LLC + SR + DC/DC topology – I discuss this in more detail later in the review.
