Fully Modular Design
A fully modular design with all black ribbon cables simplifies installation and allows you to use only the cables you need for a cleaner build.

High Power Density
The FlexGURU series features higher power density, 20% higher than any Flex PSU in the same category.

Firm Installation with Beetle Technology
FSP pioneered the development of the Beetle technology in its Flex ATX PSU. The new Beetle technology strengthens the fixation adequacy by 25%, which allows the PSU to fit into most Flex ATX chassis available on the market today.

Excellent Thermal Performance
The FlexGURU series differs from the general Flex PSU by offering a built-in inner 40mm fan. This reduces noise and offers maximum cooling at all times.
