Summary and conclusion
With its overall performance, the Pure Power FM 11 1000 is above the Corsair RM1000e, its main competitor, considering the price of these two devices.
be quiet! has developed a new platform with HEC that delivers satisfactory results. The Pure Power 11 FM has a slight edge over its direct competitor, the Corsair RM1000e, which also uses a platform from HEC, but the latter achieves higher efficiency, better PF values, and most importantly, lower noise. I expect a be quiet! product to be as quiet as possible and not noticeably outperform its significant opponents, which is the case here. This brand has earned its reputation with quietly operating products, so it has to continue this tradition, even in the slightly cheaper ranges.
Still, the Pure Power 11 FM is a decent product that I think should perhaps be priced slightly lower to be more competitive, especially in the demanding US market. Here in Germany, however, the positioning is more appropriate. The RM1000e currently costs even 10 Euros more, but has a longer warranty (7 years compared to 5 years). If you combine all of the above points, you will quickly see that there are definitely differences between the two power supplies that speak for or against one of the products.
What I would like to give the power supply, however:
- Make this device ATX v3.0 and PCIe 5.0 capable
- Reduce the average noise level (fan!)
- Tighten the load control and transient response at 12V a bit
- Lower inrush current with 230V input
- Tuning of the APFC converter to achieve higher measured values
Per | Contra |
Full power at 47°C Sufficiently high total power Efficient Highly efficient 5VSB rail Properly set OCP at 12V and OPP Quiet operation at light and medium loads Good ripple suppression Bridging time longer than 17 ms Low inrush current at 115 VAC ALPM support Option for 12VHPWR connection Fully modular Adequate spacing between peripheral connections Good solder quality 5-year warranty |
Noise at high loads Load regulation at 12V and 3.3V exceeds 1% deviation High OCP on the side rails High inrush current at 230V |
Many thanks to Aris, whose data I am allowed to use in the future and will do so, if readers want such network tests. Today’s article is once again a gauge of whether this topic resonates with you. And I also specifically chose this power supply this time because I had it myself in practical use with an NVIDIA RTX 4090 FE cranked up to 600 watts. From this point of view, the price of 150 Euros on average is really okay.
