be quiet! Straight Power 11 1000W Power Supply Review

Rating: 8.0.

Today we take a look at one of the latest power supplies from be quiet! – the Straight Power 11. This family includes models ranging in capacity from 450W to 1000W – and we look at the flagship model today. It is an 80 Plus Gold, fully modular power supply and has just been released in the United Kingdom.

One of the main selling points for a be quiet! power supply is the adoption of their SilentWings 3 fans – they are simply the quietest fans on the market, and probably my favourite. They push plenty of air, and do so without making much noise.

Many of the new models of power supplies we are reviewing are 80 Plus Platinum and Titanium certified, but the Straight Power 11 is only 80 Plus Gold Certified. Gold Certification is perfectly acceptable and the bonus is that the price points are  more competitive.

Another selling point is based around the fact that this new FSP platform design doesn't use any power transfer cables internally. This will aid airflow, reducing internal temperatures and potentially help reduce fan speeds. A SilentWings 3 fan is already quiet, but a slower spinning one under load is even better.

be quiet! Straight Power 11 Features:

  • Virtually inaudible SilentWings® 3 135mm fan
  • Funnel-shaped fan opening of the PSU case for high airflow intake
  • Wire-free inside the PSU on the DC side for enhanced cooling and longevity
  • Full cable management for maximum build flexibility
  • 80PLUS® Gold efficiency (up to 93%)
  • Powerful multi-GPU support with six PCI-Express connectors
  • Japanese 105°C-rated capacitors ensure stability and reliability
  • ErP and Energy Star 6.1 ready
  • 5-year manufacturer’s warranty
