  4. Thanks :)
  5. It has enough power but isn't Haswell certified , and has poor capacitors.
  6. I did some research about haswell compatible psu (since I'm just a newbie in building computer rig :)) and the difference is that non-certified consume more power than the certified ones?... I'll stick to what I have now and hopefully will make a perfect build next year :)

    Exactly, non-certified PSUs have a higher power consumption when idling since they don't support the low power states of the Haswell CPUs.
