The be quiet! Pure Power 13 M 1000W is one of the most silent PSUs in this Wattage category, honoring its brand name. But how it compares against the tough competition from Corsair, MSI and the rest brands? Read the full review to find out!
The be quiet! Pure Power 13 M 1000W 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 strongest member of the line, which features a maximum power output of 1000W.

The PowerZone has relatively loud transformer noise, even in standby. You can hear it from the next room. Otherwise, it’s electrically quiet — no coil whine or other weird stuff — but the base hum is quite loud. What about this one?
Can you recommend a power supply that’s completely silent, even in standby? I’ve tested a few and ended up sticking with the PowerZone 2 because it’s a good all-rounder and gets a lot of things right. But that low hum or faint squeal drives me crazy. Every morning I wake up thinking, “Damn, I forgot to switch off the power strip again before going to bed
