This Flex ATX PSU has a real power rating of 250W (continuous). Due to its small dimensions it is ideally suited for Mini-ITX applications. The small 4x4cm fan has a double ball-bearing to extend its lifetime and it's located on the inner side to reduce the noise level. GUB series also protects your PC by providing complete protection (OCP, OVP/UVP, OPP and SCP). The 80 PLUS® Bronze certification also meets the Energy Star Version 6.1 Power Supply and Power Management Requirements for Computers: Effective September 10th, 2014.
