Pls give me some advice: i5 2500k, HD 6870, 8GB DDR3

[saintshing]

Hi, this is the first time I am building my own pc so I need some advice.
I'm consider the following spec
and would like to know if there is any thing that I need to add,
like is the power supply enough?
Do I need to add more fan/cooling system?
Are the cpu, gpu, memory and hard drive compatible with the motherboard?
Would it be noisy or generate lots of heat?

Thanks in advance!

Thanks for your opinion.

Can you tell me why this psu is better?

I will just say I have used that psu in 3 builds now and has had no problems. As for you build being compatible I will say it will work fine. I have built over 50 computers in my time and have yet to have a component not work with the rest of the system. The link below is for another psu that I have used in a few builds. If you were wanting to stick with a 700watt.
