Epilogue
There aren’t many ATX v3.1 PSUs with a maximum power of 550W, so the new Pure Power 13 M with a similar capacity is a highly welcome addition to this wattage category. Not only does it offer high performance, but it also features a remarkably quiet operation, reminiscent of a passively cooled PSU. Kudos to both, be quiet! and FSP for offering such a good product in a category where there aren’t enough competing offerings. If you’re looking for an ATX v3.1 PSU with a maximum power of 550W, the Pure Power 13 M 550W is a no-brainer.
If its 3.3V OCP triggering points were set correctly, it would easily earn an award from me, but a while ago, I decided not to provide any awards to units that don’t have perfectly set protection features. This means that most of the PSUs that I review don’t receive an award, but I need to apply more pressure to brands and manufacturers regarding the settings of the protection features. I consider Hardware Busters to be the ultimate source for reliable and unbiased reviews, so I prefer to have less exposure (since when a brand receives an award, it tends to advertise it heavily) rather than effortlessly providing awards that don’t help the industry improve.
The main competitor of the Pure Power 13 M 550W is its sibling model, which delivers 100W more power and is one of the best in the 650W category. Given that both Pure Power 13 M models have exceptionally low noise output, and considering a possible low price difference, I would prefer the stronger model to be more future-proof. Now, if you don’t plan on upgrading to a more powerful GPU and believe that 550W of maximum power is sufficient, the Pure Power 13 M 550W is an ideal choice.

All in all, be quiet! The Pure Power 13 M 550W is an excellent choice, offering dead-silent operation and high performance. With this review, I have completed the entire Pure Power 13 M line, and I am now moving on to review other PSUs.
Some of you might wonder why I don’t review all models in a single review. This is because I cannot include 30-40 entries in my graphs. (Actually) I can, but they will be next to useless. Additionally, it is highly recommended to compare PSUs with others of similar capacity rather than directly comparing models belonging to the same line, which in this case includes models ranging from 550W to 1000W.
Before investing in a new power supply, read my article on the Best ATX v3.x PSUs to compare all alternative PSU offerings. You help me a lot by using my affiliate links, which don’t increase the price of the product. I receive a commission from Amazon every time you do it, which can make a significant difference for me, especially now that I am working independently, exclusively for my media, rather than for someone else.

Are you willing to evaluate the lowest category Be Quiet series as well? Most notably the brand new System Power 11 series? It has 450W and 550W members, and it is the cheapest Be Quiet PSU on the market. A lot of people are buying them, without knowing how dangerous (or safe?) they are, after the System Power 10 test turned out that they are not that terrible, contrary to the tribal knowledge (System Power 10 Bronze series has been downgraded to Tier E on the SPL PSU Tier list).
If they send them to me sure. SP used to be pretty good for their money.
Can you ask them?
Typo: All links on first page lead to 550W models except for the first one with 1000W.
