be quiet! Pure Power 13 M ATX 3.1

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 750W is the third model from this line that I evaluate. So far the higher capacity models achieved good performance and a dead silent operation, so I expect nothing less from the 750W unit. Typically, read the review to learn more!

Das be quiet! Pure Power 13 M 1000W wird für eine UVP von 170 € erhältlich sein. Es ist vollständig mit hochmoderner Technologie wie LLC-Topologie ausgestattet und hat bis zu 5 PCIe-Anschlüsse für sowohl PCIe 5.1-GPUs, als auch GPUs mit PCIe 6+2-Anschlüssen. Es sorgt für eine Kompatibilität sowohl mit gegenwärtigen als auch mit zukünftigen Grafikkarten sowie dem ATX12V-3.1-Standard

Just like with most power supply units released by be quiet! to date the Pure Power 13M 1000W performed extremely well during my tests both in terms of rail stability and noise levels (be quiet! fans have always done well here). FSP is among the top power supply manufacturers around, so this wasn’t really a surprise. What was a surprise is that they used Taiwanese capacitors and even though Taiwan leads the electronics industry in many things when it comes to capacitors Japanese ones have always been the top choice for users all over the globe (Chinsan capacitors however have a very good track record).

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!

Mit etwas Verspätung gesellt sich nun auch das 1200-Watt-Modell zur neuen Pure Power 13M Serie und macht sie damit wieder zur am breitesten aufgelegten Netzteilserie am Markt Startend bei kleinen 550 Watt für Office-PCs, kleine NAS-Systeme oder andere sparsame PCs bis hin zu den 1000 und 1200 Watt für Highend-PCs liefert die Serie nun für jeden die passende Leistung. Alleine für diese breite Aufstellung des Netzteils muss man be quiet! schon Lob aussprechen. Denn es gibt durchaus viele Anwendungen im PC-Bereich, bei denen man eben keine 750 Watt oder mehr braucht und somit Ressourcen sparen kann.

If you are looking for a high-capacity power supply that provides the latest ATX 3.1 and PCIe 5.1 standards at a very competitive price, the Pure Power 13 M 1200W is an excellent choice. At £149.99, it is priced to match several major rivals. However, I can’t ignore the fantastic voltage stability and a generous ten-year manufacturer’s warranty, especially on such a powerful unit. While the pure enthusiast may be more tempted by the more premium Straight Power models, the price difference isn’t going to be for everyone.

The Pure Power 13 M 1200W ultimately stands out for its electrical consistency, delivering stable 12V performance even when pushed by heavy GPU transients or sustained multi‑core workloads. Its internal layout is clean, the modular interface is well‑executed, and the overall construction reflects the same disciplined engineering be quiet! has built its reputation on. That said, the acoustic behavior does shift once the unit is operating near its upper range, with the fan becoming more noticeable under prolonged high‑load scenarios. And while the PSU uses reliable Taiwanese Teapo capacitors, this is largely a result of the unit being manufactured by CWT, which recently has been sourcing capacitors from Teapo for these platforms. Even so, the combination of rail stability, efficiency, and solid build quality makes it a strong option for systems that demand dependable high‑capacity power delivery.

The be quiet! Pure Power 13 M 650W is the forth in line model of the line that I will evaluate. Expect dead low noise and high performance, given my experience so far with the rest members of the family. Is this the ideal 650W ATX v3.1 PSU? Read the full review to find out!

The be quiet! Pure Power 13 M 550W is the last of the line that I will evaluate. This is one of the very few ATX v3.1 compliant PSUs with only 550W max power.
