Is the 150W power supply that comes with Antec ISK 300-150 enough for the following build.

  • i7-4790k
    MSI Z97I AC Motherboard
    g skill ripjaws 1600 mhz 8GB ram
    samsung evo 850 120gb SSD
    No. Graphics card
    Will be overclocking
I need a compact CPU.

If the inbuilt power supply is not enough, Can I have a external power supply unit for the same Antec ISK 300-150 case. Pls. suggest.
 
No it will not be enough, especially if you are overclocking.

Do you know what form factor the 150W supply is ?

I would suggest an itx case such as the Cooler Maste elite 110,120 or 130 as they can all fit standard ATX power supplies but are still very compact and have decent airflow.

I will not add a dedicated GPU. If I don't overclock it, is it enough?.

If I need to overclock will 250w be enough?.
