400w is still a no, but 700w would be fine.

Which 680 are you going to get? PCI express 3.0? x8? x16?

Make sure your mobo has the proper slot. Usually oem mobos are crap.

Also instead of a A8 3870k, try to find a Athlon 651k. You're not going to be able to overclock on that mobo though.

I recommend selling your HP and starting from scratch.
