Voltage HELP PLS

[Waffle404]

Hi I'm from Italy and I'm building a new PC; I'm buying these parts from America

CPU: I5 3570 (3.40 GHz)
GPU: EVGA GTX 760 SC
RAM: 8GB Corsair Vengeance 1600MHz
HDD: Seagate Barracuda 7200RPM 1TB
MOTHERBOARD: Asus P8Z77 V LK
CASE:Corsair Carbide 400R (from Italy)
PSU: OCZ ZT 750W (from Italy)
OS: Windows 7 64bit
Optical drive: old one
Monitor: Samsung Sync Master BX2240 (old one)

So I'm not sure if all these parts are compatible in terms of voltage,I don't want my PC to fry as soon as I give it power...
Also could you tell me if they all go well together and if the PSU is ok? I know it looks like a bit of an overkill but the Nvidia site says 500W PSU so...
Thanks for your help

Your good, the system only uses as much power as is needed - It's not like you flip it on and it suges all the wattage through everything
