Will a seasonic 430w power a 4850?

Not the writer, just attempting to explain the ratings. Seasonic isn't lying, the PSU can deliver 30A on the +3.3V as long as you don't load down any of the other rails. And it can deliver 30A on the +5V if you don't load down any other rails. And if you load down both +3.3V and +5V but none of the other rails, it can only deliver 150w (about 18A on each rail). That's where the combined rating comes from. Same story for the +12V rails. Which is basically what the article said, but here it is in my own words since you'd rather not read it.

Please, read my correction above. "Editing: I did the maths wrong. 30*5=150. Ok."
 
Its a classic ATX12V Rev. 2.0 unit, that adheres to the design guidance for 400W configurations almost exactly:

Notice that +3.3V and +5.0V are limited to 150W combined.


so based on this, I can run a 4870?? (not including the second pcie connector required)

Also, if I installed the 4850 and everything works fine would it be ok to overclock? Does pushing the power supply lower the potential headroom I had before, or is it simply dangerous to try?

what about your CPU? What is it and is it OCed?
