FSP Flex ATX 250W Fortron FlexGURU 250-50FGBBI

The PSU seems sturdy, however the noise is absolutely atrocious and unfortunately unacceptable for a SFFPC. There is both the air noise and a sort of a whine from the fan. I bought this thinking it is quieter than other Flex PSUs, but if this is quieter I can't imagine how loud a "normal" Flex PSU is.If you are building a SFFPC this is not appropriate unfortunately, I recommend considering some other solution.

This is a nice, efficient power supply. I believe one of the best flex ATX supplies you can get. The only disadvantage is that it isn't really 'modular', you probably need all the cables anyway.
