I am planning on buying all of this but need to know what the correct power supply would be. I was thinking 750 watt but a friend says to go with 650 watt, your thoughts?

ASUS P8Z77-V Deluxe
Intel Core i7-3770K Quad-Core Processor 3.5 GHz
Western Digital Caviar Black 1 TB SATA III 7200 RPM
G.SKILL Ripjaws X Series 16GB
ASUS Blu-ray Burner SATA
Cooler Master Hyper 212 Plus CPU Fan
Cooler Master HAF X RC-942 Case

+ two Seagate Barracuda 250GB Hard Drives.

Considering that GTX 650 Tis don't even use 100W under load and that your CPU is a 77 watt part, your maximum power consumption is very unlikely to be above 200W, therefore 650W is overkill even if you add another GTX 650 Ti.

So you should only get a 650/750W PSU if you have serious plans to upgrade your GPU in the future to something much more power hungry.
