The be quiet! Pure Power 13 M 850W is dead silent but is this enough to allow it to compete with the rest offerings in the tough 850W category? Read the full review to find out, no spoilers!
The be quiet! Pure Power 13 M 850W is (or will be) included in my best ATX v3.x & PCIe 5.x PSU picks article.
The Pure Power 13 M series by be quiet! is a line of fully modular ATX power supplies aimed at users who want a balance of performance, efficiency, and silent operation. All models are certified by Cybenetics, achieving Platinum efficiency and a perfect noise score (LAMBDA A++). One of the standout features is full support for the ATX 3.1 and PCIe 5.1 standards, ensuring compatibility with the latest GPUs and next-gen components, including high-powered cards like the NVIDIA RTX 40/50 series. It is not common to see a 550W ATX v3.1 compliant power supply, but the Pure Power 13 M line does.

From a design standpoint, the Pure Power 13 M units emphasize quiet operation, employing a custom 120mm fan from be quiet! known for its low noise levels even under load. The modular cabling system is a practical addition, helping reduce clutter and improve airflow within the case. With models ranging from 550W to 1000W, the series offers flexibility for different system builds, from mid-range desktops to high-performance gaming rigs. This is not a high-end line, targeting users who want a good-performing and quiet PSU without breaking the bank.
In today’s review, I will evaluate the second strongest member of the line, which features a maximum power output of 850W.

Thank you for the review Ari! Looking forward 550w version of the Pure Power 13M if you can review it in near future. It costs 101,90€ in Europe and probably the best offering at that price range with 10yr warranty for a low power high quality PSU.
I´m coming from Seasonic G-360 (360w) 80 Plus Gold which i bought 1/2015, but for the new system could be wise to change it even though G360 is high quality PSU that in test bench put out 450w before shut down and had high efficiency (90,7% 50% / 88.3% 20%), Japanese 105°C capacitors, very silent ADDA fan etc. I might still get +/- 5 extra years out of this, but if it kills other parts when dying then it gets expensive. I´m hoping to get similar quality for new PSU (reliable, silent, efficient) and don´t need high power version due to opting for modest 6C/12T CPU (65w TDP) and using old GTX 1060 3GB GPU for random gaming, internet and HTPC use. Unless you say to me that i should keep the current one as long it lasts?
I will do it in time. I will review the entire line, I just take it in order of Wattage.
Hi, Which one would you recommend at 850 watts? The corsair rm850x or the be quiet! pure power 13m? I would love to hear your opinion on which one would be a better option! The pricing is the exact same where I live.
Tough choice. Both are very good. I really cannot tell; it’s down to what you want more. I like the Corsair RMx series a lot; it’s among my favorite choices for builds. However, the Pure Power 13m is dead silent, which is not to say the RMx is noisy. Having the same price doesn’t help LOL
