The be quiet! Pure Power 10 700W CM is another capable power supply release from the highly regarded German company. It was able to deliver high quality power closer to 800 watts, before safely shutting down. As we would expect from be quiet! the build quality is excellent, and the paint work and dramatic orange accenting is very appealing. The only negative point we could make on the appearance is that the surface of the chassis is a fingerprint magnet.

As before, cosmetically we love the appearance of the Pure Power 10 unit – we like the orange trim around the fan housing which has sometimes been omitted on be quiet! supplies (such as the be quiet! Pure Power L8 series). The modular cables are all very high quality and this unit is capable of handling a powerful dual card SLI or Crossfire build.

Load regulation is stellar and the rails hold close to reference levels, which is impressive. Ripple suppression has been improved over the previous version we tested last year and technically it didn't show any potential for concerns across several days of heavy stress testing.

So, I have handed out a lot of praise for the cosmetic appearance and the technical proficiency of the unit, however I do need to raise a concern.

I have raised this with bequiet! consecutively for three years after reviewing the Pure Power 8 and Pure Power 9. be quiet! are cutting costs by using low grade 85c rated Chinese capacitors by TEAPO. I appreciate that many sources say Chinese capacitors are getting better, but I can only base my decisions on my own findings. I have seen TEAPO capacitors leak and explode in our labs over the last 5 years.

It really is far from reassuring to see be quiet! using them in any of their products, especially as the company place a focus on ‘quality German engineering' and the standards of German build quality. Sure, some people might never have a problem with the unit, but my experiences in our own labs would always raise a point of concern over this.

This unit is priced around £100 in the United Kingdom, so I don't think there is any room for 85c TEAPO capacitors in this Pure Power 10 product. be quiet! should spend the extra 1-2 euros and adopt Nippon Chemi Con or Rubycon capacitors – to remove all doubt of potential longer term failures.

We have no store links as we go live today, but you can expect to see stock on leading etailers such as Overclockers UK. They currently are stocking the Pure Power 9 700w HERE at £99.95 inc vat, and it is likely stock will arrive with them this week. We have been told there will be no changes in pricing over the Pure Power 9 range.

Pros:

• quality paint work and exterior build.
• very low noise fan.
• high grade modular cables.
• can deliver 777 watts before shutting down.
• technically a very solid design.

Cons:

• 85C Chinese capacitors used which is disappointing to see in ANY be quiet! product.
• 80 Plus Gold Certification would have been better.
• shipping box could be better, the power supply can move around a little during transit.

Kitguru says: Another very competent power supply from be quiet!. Technically the be quiet! Pure Power 10 700W CM proved a very good performer in our tests.
