An impressive supply for quality single-GPU builds. German PSU manufacturer be quiet! released an update to its popular, premium Dark Power Pro line just a short while back. Now referred to as the 11-series range, the original trio, understandably, focused on higher wattages and premium pricing. The 850W, 1,000W and 1,200W models performed well and were ripe for a recommendation to the enthusiasts who wanted super-stable power at high loads, but those with more modest energy requirements were left wanting 80 PLUS Platinum-level efficiency.

Though that isn't the case as of today; be quiet! has extended the Dark Power Pro 11 range to accommodate 550W, 650W and 750W capacities. Designing for lower capacities is inherently more tricky, explaining why the mainstream supplies are later to market.
