We would like to thank be quiet! for supplying the review sample.

The be quiet! Pure Power 11 FM (Fully Modular) line lists three models of different capacities: 550 W, 650 W, and 750 W. I will take a look at the strongest member of the line to check on how it fares against the competition in the 750 W Gold category, including the new Corsair RM750x (2021) with the Magnetic Levitation fan, Cooler Master V750, MWE Gold 750, and the XPG Core Reactor 750. A strong competitor is also the Seasonic GX-750, but I don't have 230 V data for this model.

According to be quiet!, all Pure Power 11 FM models operate quietly. Thanks to the fully modular cable, installation and cable management will be easier than with the semi-modular and non-modular Pure Power 11 models. For the new Pure Power 11 FM line, be quiet! cooperated with CWT and used a new platform. The Pure Power 11 and Pure Power 11 CM units are based on FSP platforms that are not as capable.

The 750 W fully modular Pure Power unit is fully compliant with the ATX12V v2.52 specification. Hence, it's highly efficiency under incredibly light loads and compatible with Alternative Sleep Mode. The maximum operating temperature for continuous full-power delivery is set to 40°C, and a quality SilentWings fan measuring 120 mm across handles cooling.

Normally, 12V2 would be stronger since it has both EPS and two PCIe connectors.
