When it comes to its form factor, the PSU spots the 2.52 version. For the form factor EPS, it’s the 12V 2.92 version that’s being used.

Hands-on with the be quiet! Dark Power 12 1000W PSU

be quiet! Is known for its products’ silent operation, but we wanted to test if these claims are true.

For the noise levels, the Dark Power 12 1000W had an idle noise of 31dBA. With average loads, it operated with 37dBA noise levels and that’s pretty good.

The fan speed profile was highly relaxed under normal operating temperatures. As a result, the fan noise output didn’t exceed 37dBA. This was really quiet, and we had to move close to hear the fans working. 

The PSU was able to handle high operating temperatures. But of course, the fans started increasing in noise under full load.

be quiet! Dark Power 12 1000W PSU utilises a new FSP platform of ultra high efficiency in every load region. 

Other than that, it keeps the output of noise low, and that’s even during harsh conditions. So if you want to build a quiet yet efficient system, the Dark Power 12 1000W PSU is ideal. It’ll be the best power supply to use for your build. 

The Dark Power 12 1000W PSU is a bit on the pricey side, so you’ll need to invest in it. It’s something we’d highly recommend since it performs great, it looks good, and it’s a very quiet PSU to have.

be quiet! Dark Power 12 1000W PSU Review Summary

The Dark Power 12 1000W is an excellently designed PSU inside and out, so its 10-year warranty isn’t a risk. Its exterior design has a great-looking black aesthetic that looks solid and durable, making it stand out from the crowd. 

We usually don’t pay a lot of concern for a product’s exterior design. But with the Dark Power 12 1000W, it immediately caught our attention.

In fact, we’re glad that be quiet! didn’t include RGB lighting for this product. RGB would only increase the PSU’s price without adding benefits to its performance.

For its components, it utilises top-notch parts like the Japanese capacitors, modular cables, and Silent Wings fan.

The Dark Power 12 1000W isn’t exactly a smaller version of the Dark Power 12 Pro, but it’s quite close. Both power supply units have the same premium modular design, silent fan, Titanium certification, and built-in overclocking control. It’s less expensive than the latter which is excellent for those wanting to spend less on a high-end PSU.

The Dark Power 12 isn’t as fancy and expensive as its predecessor, but it’s well-constructed and excels in performance. It’s an excellent choice for PC builders who don’t need a high-end PSU. And aside from this 1000W model, you can also choose from the 750W and 850W variants.

Overall, we were satisfied with the be quiet! Dark Power 12 1000W PSU and we highly recommend it. If you want to get your hands on this product, it’s available in various stores worldwide. Check out the company’s store locator to find authorised sellers and retailers.
