Users can expect to buy the product around 125 Euro (including VAT) according to the be quiet! press release. The Pure Power 11 FM series are middle category power supplies, with pricing in mind but also good performance. The retail package is well designed and includes at the front all the needed information for users. As with all be quiet! PurePower 11 series, the 850watt has five (5) years of warranty.

Everything is well packaged.

There is a printed manual inside and the main PSU is wrapped around plastic bubble bag.

The PSU has the typical ATX power supply dimensions, meaning it will fit in most cases. At the top there is a big 120mm fan with low noise levels. be quiet! says that the fan is thermally governed to strike the best balance between effective cooling and quietness. Airflow-optimized fan blades reduce turbulence, enabling best-in-class quiet functionality and the almost inaudible operation.

The power supply has a matte black finish like most of the tested power supplies we have recently have seen at our labs. All the edges are not sharp, so you can handle it without any worries. The rear has a honeycomb design, that helps lower PSU's internal temperature, since drives the produced hot air out of the case.

At the back we can find the power ratings of the product. The power supply has two +12V rails with two rails, one is getting 40Amps and the other 36Amps output. The +5V boosts 22A, while the +3.3V rail 22A. Lastly, the +5VSB gives another 3A. The dual rail design for sure would be ideal for sudden high load scenarios even in general single rail 12V are better.

There are several cables included for users to connect many devices:
