Excellent power supply. I haven't had a better experience yet. We're talking about 750W, Platinum Complete silence. from 10 cm. You can’t hear him at all!!! Under load up to 500 W the same. The fan runs 200-300 rpm. The most important thing for me is that there is no throttle squeak/buzz/buzz. Complete silence. In the old passive SeaSonic at 400W, it was just a high-frequency squeak that was produced. Not found  Aleksey Kalita: use be quiet! BN307 few months |
Broke down after 2 months of use (purchased for subsequent computer upgrade in March 2020). PC configuration: i5 9600k + RTX 2070S. The computer shut off and something smelled burnt, turned out to be the power supply, the computer was in desktop mode, and there were no storms or power surges, the second home PC was working fine at that moment. Returned it under warranty and got a refund, bought a slightly cheaper EVGA SuperNOVA 650 PSU. PS Will never buy BeQuiet again, at work two 500W "system power 9" units failed even in office PC configurations. Quiet and seemed reliable Broke after 2 months |
Burned on the first day of use during the game Metro Exodus 05/17/2020 Looks high-quality but did not meet expectations Burned quickly Anton: |
