A fairly powerful, high-end power supply unit from German manufacturer be quiet!, built with a focus on supporting modern power standards and maintaining a low noise level even under heavy load. In terms of cost, the model is positioned between the mid and high price range and belongs to the popular Pure Power series. According to the manufacturer, be quiet! Pure Power 13 M will be an equally excellent choice for a modern gaming PC and workstations involved in video editing, 3D graphics, and any tasks where prolonged loads coexist with the need for silence.
Cooling is provided by a 120mm fan with a sleeve bearing. It supports ZERO-RPM mode, where the fan completely stops at low loads. Even at 100% power, the noise level does not exceed 21 dB. This feature will be especially valuable when working with audio, in studios, and in home environments where silence is important. The 80+ Gold certificate and a fairly high efficiency of up to 94% at 50% load help reduce energy consumption and decrease heat emission, which is particularly noticeable during round-the-clock operation.
Compatibility with ATX 3.1 and PCIe 5.1 standards ensures readiness for new generations of graphics cards and processors. The +12 V power reserve allows connecting systems with multiple drives and powerful GPUs without fearing instability during peak loads. The modular cable system helps neatly organize the build and maintain the correct airflow in the case. The built-in protection system covers all critical scenarios, including protection against overheating, overload, overvoltage, and short circuits. A ten-year warranty highlights the high quality of the device and the manufacturer's confidence in their product.

Review of the 850W version. The components inside are quite decent, judging by existing tests and teardowns. Compared to competitors, I wouldn't say it's globally more expensive because of the be quiet! brand (I bought it in a "white" store for 176 EUR, and saw it on sale for around 161 EUR). Generally, as I see it, the brand's budget lines get a bad rap, but in the mid-range (this model) and high-end (which are really overpriced) segments, the devices are quite decent. Quiet. From my estimates, it doesn't turn on the fan until around a 400W load. I had a Ryzen 5700x system (65W) + RX 7800XT (274W), and everything else also consumes something, but it never turned on even under full load. After replacing the card with a 9070XT (304+W), it started to activate, but the RPMs were minimal. I just don't have anything that fully loads it, but in any case, I can't hear it in any scenario because under load, the system's noise overall will be noticeably higher than from it. Additionally, the manufacturer's claims and all the network tests indicate that it is very quiet even at high speeds. Plus, the fan doesn't spin unnecessarily, and when it turns on, it's at minimal RPMs = its lifespan should be long. In my unit, there is no component whine, either without load or under load (although I haven't heavily loaded it, simply because there's no way to). In the new 16-pin connector for the graphics card, all pins sit quite evenly (at the same depth) and don't wobble back and forth, as sometimes happens with some cables. And it's round, not flat, which makes bending easier if necessary. I'm a bit surprised by the implementation of the video card power, which is 8pin. It is claimed to be 4x8pin, and it is, but with two cables. Accordingly, it has 2 connectors on the unit, but they are not 8pin, they are 12. Not bad. But the cables themselves are different (you can see this in the photo). One goes with two parallel strands, each using 6 contacts from the connector on the unit and goes to its 8pin connector on the video card. But the second has two sequential 8pin connectors, and the connector to the unit does not use 4 out of the 12 pins. My question is, why do it that way? So they made two big connectors on the unit just to save on one cable and leave some contacts unused? Especially since the second included cable is full-fledged? Wow. Many manufacturers just make an 8pin on the unit and hang 2 sequential connectors on it, here they made 12pin on the unit, which might not be globally different, but it costs more. And then they save on the cable. And it's clear that it's somehow calculated and everything should be fine, but still. Although in fact, if you have a card with 2x8, you can just use the one with parallels, if it’s 3x8, then take two parallels and one from the sequential. And there are no 4x8 cards in general at the moment.  Dima P: use be quiet! BP027 few months |
The 750W version doesn’t exit the fanless mode even under a 300W load (simultaneous stress test of a CPU at 65W and a GPU at 180W, plus peripherals and motherboard). It has withstood repeated power surges in the network of 300V and more, with some protection handled by an ordinary power strip with a varistor (but its activation threshold is around 400V, so I assume the PSU reacted faster). In the Pure Power 12M, the same fan is always running and can be heard when the PC is idle. In this model, at least it will start together with other fans and get lost in the air noise. I think it’s about time to design models with the possibility of replacing the fan without losing the warranty. Restrained design, good component base, fanless mode, reliable cables for any occasion. As with all be quiet! models that are not from the top segment, this one comes with a standard rifle bearing fan. There's a paired PCIE cable, so if you only have one connector on your video card, you'll have to tuck the extra cable somewhere in the case. Vitaliy: use be quiet! BP026 few months |
