A few months ago we introduced you to one of the three models we then had Be Quiet! had presented on the market, it was the 750W model, which had positively surprised us for its great malleability and load resistance. We were therefore left with a promise from the German manufacturer, one that would land on the market with new solutions from the same family, raising the bar even more, and today, we are here to talk to you about the very good model. 1000W.







Introduced the new models from 850W e 1000W, revised internally, with first-class components, and are created to offer the best to the most demanding, supporting the most demanding configurations.

We have the BN325 model, in super preview just to let you know, a few days ago we announced the launch. The new model has a goal, to be completely modular, to fully support overclocking operations, which we know are typical of the most powerful configurations. Pure Power 11FM 1000W is an 80 PLUS Gold model, Dual Rail for 12V, therefore a guaranteed delivery stability, and much more, which you will discover in the full review.

In the package we find the typical and now solid quality to which Be Quiet! got us used to it. We have one 24mm 20/550-pin ATX connector, two 8mm 4V 12/600-pin EPS / ATX cables, two 8mm and 6mm PCIe 500/150-pin connectors respectively, one SATA / MOLEX cable and two Classic SATA. We then have a 120mm fluid bearing type fan, which ensures a noise range that should dance in the range tra  32.1 dB(A) e 23.6 dB(A).







It is made of aluminum with a great absolutely premium build quality, as well as the cable entries, of excellent quality. And the design, albeit simple, doesn't mind at all. The cable entry is perfect, as is the extraction, which is not difficult as unfortunately not infrequently happens with lower-end PSUs. The new product features flat black cables for all common connections while an ATX 20 + 4 pin power cable with a black sheath. The power supply has a size of 160mm x 150mm x 86mm. This PSU however, does not have a PCIe 5.0 power connector, but we will not see it at the moment, it should be a standard that should be used with next generation high-end graphics cards, all in the making.
