Hey guys, I have a problem I am facing, I want to get a PC with the following specs:
i5 4670k STOCK (Will overclock to 4.2Ghz)

*EDIT(Updated CPU Cooler)* Noctua NH-D14

Gigabyte z87-HD3

8GB DDR3 1600MHZ Ram

1TB SATA III HDD

HD 7950 STOCK (Will OC to 1125 MIN)

650w CORSAIR VS.

The problem I am having is that I'm not sure if I should go ahead and purchase the PC or not. The reason for this is because I looked around and people say that you need more PSU power to OC your GPU and CPU. I will overclock both quite a bit but they will be stable. I just want to clarify if the PSU will be enough power to OC to the amount I want (Given above). Any help will be appreciated.

Also, I have 2-3 other PSUs which I can choose from as they're in my budget.
They are:
650W Corsair TX V2

650W Corsair TX Modular.

Please help me out! Thanks!

650W will be enough to get a good OC with that build. Just don't plan on heavy hardware upgrades. Modular psu always comes in handy. But if your case is big enough, nonmodular is ok.

Are you 100% sure that if I overclock both, this will be enough PSU power for BOTH overclocked? Keep in mind how much I will overclock my CPU and GPU (given above)!

It could be close, but should work unless it's a great OC. To be sure, and above all to still have a good efficiency when OC'd, you could opt for a 700W or 750W. I'm ordering the XFX PRO750W for my next build.

Looks like a decent build, PSU i would go with the Corsair Modular TX 650w unit as there easier to work with, as for your CPU cooler while the noctua is a very good air cooler it massive and will swallow your whole case, id be more inclined to go with a similar performing H80i all in one liquid cooling unit or something similar.

Glad someone confirms 650W would do. But the Noctua really fits in almost any normal case. Unless you'd buy some tiny mATX case or a very small tower, you wont have any problem. Besides ... its a beauty :D

I will go ahead with the top range 650w Modular TX then. Thanks a lot.

That's true. My case is massive haha! Thanks for all the help and I will decide soon. I won't be taking 700w as I'm sure 650w is enough! Thanks!
