Looks fine , but the 550 W of the PSU would be enough for your build . The components also look a bit expensive . For example you could get GTX 1070 video cards starting at 430 Euroscardoveralllist # sorta 8 c 369 , and the EVGA SC , MSI Gaming or Gigabyte G 1 Gaming models are not worse than the Asus ROG Strix . Unfortunately PCPP doesn ' t cover the European markets very well . Many available items don ' t show up or are a listed with outrages prices . Still a great tool to plan PC builds , but terrible for finding good prices . For comparison here is the same build with the suggested changes with German prices .

The build would work fine . Just change the PSU . You really don ' t need more than roughly 500 watts .
