be quiet! Straight Power 11 Platinum PSU Review

The Straight Power PSUs are designed to be an excellent middle of the road when it comes to power delivery and the balance between noise and efficiency.  The base model starting Straight Power Platinum starts at 550w and finishes out at 1200w to encompass every high-end enthusiast build you could imagine.  The PSUs in Platinum feature an 80plus Platinum rating which delivers a 92% efficiency rating at 50% loading meaning that more power is converted into usable power than excessive heat.

The primary cooling fan is 135mm bequiet unit using SilentWings 3 technology.  The fan is a custom size for the bequiet PSUs though features all the same specs including a virtually inaudible 15.5dBA sound rating.  The blades feature a high pressure design and super long lifespan of 300k hours.

The Straight Power 11 1000w features a fully modular cable design that allows you to use only the cables required for your system.  Unlike other modular PSUs you will find a different power plug for each cable type.  PCI Express cables are located in the middle feature a unique 12pin plug design.  Drives are located along the edge and use a flat 5pin plug design and the 12v CPU power are available as a dual P8 connector next to the main 24pin ATX cable block.

Unlike on other bequiet power supplies the Straight Power 11 doesn’t feature the OC key or fan headers.  Truth is nobody needs fan control at the PSU level and only a select few hardware enthusiasts would benefit from the OC Key which binds the 12v rail into a single mono block.
