That greatly depends on the rest of the configuration. For a Haswell or Skylake based system, that wouldn't be a very good choice at all unless you want to turn off the C6/C7 states in the bios since that unit is not Haswell/Intel low power state compatible.
There are also a whole lot of cards that won't run properly or safely on that 520w unit, or at the very least, call for a higher capacity unit according to recommendations, so knowing the card model or desired card model is kind of important before making a PSU recommendation. If for example, he wanted to run a 380x, that unit would not meet recommendations, especially if the CPU is also going to be overclocked.
