Epilogue
We have a new winner in the 650W category, where there are not many ATX v3.1 offerings. This is excellent news for users seeking a mid-capacity PSU that offers good performance and exceptionally low noise output. The Pure Power 13 M 650W honors its brand’s name with its silent operation, which resembles that of a passively cooled PSU. Moreover, the same unit occupies the top place in overall performance in this wattage category, with the XPG Core Reactor II in second place, also featuring a similar capacity, and the MSI MAG A650GLS in third place. be quiet! hit the 650W category hard, and I hope that future production batches retain the same good performance, especially the same fan speed profile.
The main competitor of the Pure Power 13 M 650W is the MSI MAG A650GLS. The performance difference between these two models is notable, favoring the former, and the same is true for noise output, where the difference reaches 20 dBA. If be quiet! releases the Pure Power 13 M 650W at a good price, it will be difficult for the competition to catch up.
