Hello all!

I have been trying to conceptualize the power consumption needs of this build. I have input these components to both ASUS' and eXtreme Recommended Power Supply calculator.
ASUS's: 450W
eXtreme Power Supply: 463 to 518W

Under these calculations, would a 600W be ideal or could I get away with a 500W PSU? I'm thinking corsair will be a good brand to buy from. Any other considerations for these PSU requirements?

    The CX Series power supplies are very poor.

    Get this one for your build , it's a good fit , and made by the best SEASONIC.

  2. Looks great! I'm sure the credibility of seasonic is solid. And the 550W should be ideal. Only thing is and this of course goes with the territory of a mITX build, because it is non-modular do you think with proper cable management the PSU will keep its longevity?

    I'm still a little unsure of this one in particular because of the difficult time I'll have using a non-modular PSU for a small case/mITX build.
  3. Yes it's a very solid unit.
  4. Ok. Thanks for the input! +1
  5. No problem!
