PC ASSEMBLY HELP IF THIS IS OK?

looks good to me. Make sure you get a good brand-name PSU though.
Corsair, PC Power & Cooling, Seasonic, etc.

Research specific models and check out reviews, esp on sites such as bit-tech and jonnyguru

ok.. but what if i would get generic psu.. i mean. not branded psu... hows that? is it ok?

It will probably sound like a small hairdrier and cost more money as it is likely to be inefficient. Would you buy a generic car? You buy a brand name as they are more likely to give good performance over time.

Looks like you're spending a decent amount on the rest of the components, why cheap out on the one component that could break every single other?

For your system, all you need is a Corsair 400CX (30 amp 12 volt rail)

If you know that you will upgrade soon, get a Corsair 550VX (41 amp 12 volt rail)

Or even a Antec 500 watt BASIQ

Any of these are much better than a 600 watt generic PSU.
