Be Quiet! Dark Power Pro 10 850W – Introduction

Some weeks ago we had a look at the Dark Power Pro 10 650W, the first power supply that we received from Be Quiet!, an European manufacturer which is just starting to enter the North American markets. Today we are having our second review of a Be Quiet! power supply, the Dark Power Pro 10 850W. Although the name and even the appearance of these two products is virtually identical, the 850W version is based on an entirely different design which boasts even better performance and higher efficiency.  Can it really be that much better than the already excellent 650W version? We will soon find out.

Unfortunately, although they are readily available in Europe and even some Asian countries, availability remains a great issue with Be Quiet’s products in the US and Canada. The 850W version can be found at Newegg for $239.99 plus $5.99 shipping. This is slightly higher than the MSRP of the power supply is virtually no competition at all in the North American market as very few retailers carry Be Quiet! power supplies. The Be Quiet! Dark Power Pro 10 MSRP prices for the US market are:
