3. Tests - Conclusion
The included 120mm fan is a 4-pole fan motor and spins up to 1300rpm with 22.5dB (A) at 100% load. be quiet! lists the included fan as their own design mainly for silence. The overall noise seems very good.
For our tests, we used the following test PC system:

- Asus ProArt X670E-CREATOR WIFI Motherboard with the latest BIOS
- MSI 4070 GAMING X TRIO 12G with the latest Nvidia Drivers installed

Stressing the Pure Power 12 750Watt needs something equal to an NVIDIA 4070 Graphics card, since the used in other tests MSI 4090 isn't proper for this PSU category. We didn't notice any problems during our testing and the newly designed VGA connector that the ATX3.1 standard orders worked very well, in general, we didn't have any problems with the 12VHPWR connector in our tests with the various PSU we also had tested in past.
- Conslusion
The be quiet! Pure Power 12 750Watt power supply series is an update to the already established Pure Power 12 M series, adopting the latest ATX standard and especially the ATX 3.1 that has a re-design of the 12VHPWR connector for NVIDIA graphic cards since all AMD cards are still using the PCI-e 6+2-pin connector. The new series packs an 80Plus Gold certification and the new improved 120mm fan can work even at full load at low noise levels. Users can select from 650Watt up to 1000Watt models, depending on their system needs. The retail price of the 750Watt model is around $104.90 / €104.90 / £89.99 and maybe in the upcoming Black Friday 2024, users will see even further retail price drops. Overall the Pure Power 12 series are entry-level power supplies from be quiet! and apart from the "be quiet!" brand name also includes 10 years of warranty and good efficiency at their operating margins. The fixed cables, while somewhat annoying have great quality and if you have a medium size PC case you won't have any problem managing them around.
