Power Supply Consumption Safety

[Kirbyarm]

Hello again everyone!

I have just three final questions before I start hitting the checkout buttons. The first question statement is, if an 80 PLUS GOLD 650W power supply is safe and sufficient to run a PC with these components:

-ASUS GeForce GTX 770 2GB 256-Bit
-Intel Core i7-4770K Haswell 3.5GHz
-SSD: SAMSUNG 840 EVO @ 250GB SATA 6Gb/s
-Motherboard: MSI Z87-G45 @ HDMI SATA 6Gb/s USB 3.0
-G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 1866
-SeaSonic SSR-650RM 650W ATX12V
-Cooler Master Hyper 212 EVO with 2 fans for push-pull
-ASUS DVD Burner
-1 TB HDD

I know the power supply wasn't needed in the list for question one, but it is for question two, which is, are all of the above components compatible with each other, and can I surely build a working PC with these specific components?

Third question is can I use Windows 7, or are the components too modern and will require Windows 8?

Yes, it's enough. Though I'm sure you know the i7-4770k is overkill unless you're rendering stuff.

Also, Windows 7 will run any components that Windows 8 will.

Thank you for the answers. How about the second question? Are those components compatible to build together in one PC?

Yes I am aware that it is overkill, but I don't want to settle for the non-HT i5 4670k as I really do want HT.

The CPU + motherboard have matching sockets. The cooler fits the correct socket. The RAM is correct. The motherboard has the right slots. Etc. It should be fine, just as long as your case fits full ATX motherboards.
