How to find the right voltage of power supply for this systems?

ofive · Feb 12, 2014

Hello to all members.
I want to build two desktop computers and have bought all parts in microcenter store. I haven't got power supply for none of them. Can anyone help me to decide which is the right voltage for each system. Here are the parts:
System 1:
Core i5 4670K
AsRock Z87 PRO4
840 EVO
HDD Maxtor 160GB 7200
Ballistix Sport 8GB DDR3 1600
PNY GeForce GTX 650 Ti 1024MB

System 2:
Core i7 4770K
AsRock Z87 PRO4
840 EVO
WD Blue 1TB 7200
EVGA GeForce GTX 660 Superclocked 2048MB
(Ballistix Sport 8GB DDR3 1600)*2=16GB

Also i will add a DVD-RW for each so please consider this too.

I would be thankful if anyone help me with this.
Best regards.

A decent 550W will run both builds.

Is this 600W ok even if i overclock the processor or in the second system the graphic card too?

Glad to assist.

Don't forget an aftermarket cooler if you overclock.
