I was looking for some psus and I found the M12II series of SeaSonic 620W. Will it run a 4770k or a 4670k?

If not, may I have some power supply recommendations? Thanks. :)

Yes it will run those Haswell cpus without any problems. You should also know that all PSU on the market right now are compatible with Haswell CPUs, it's just that some of them can't put Haswell system into C6/C7 power saving states.

Yes, some say that you need to configure it in your bios for it to be giving such small amount of power to your cpu, since old power supplies are unable of doing that. I checked this site http://www.seasonic.com/product/pc_retail.jsp where most seasonic's power supplies are mentioned and it says that it's not haswell ready. Should I be worried?

No you shouldn't. Just need to disable C6/C7 from BIOS.

Move up to the M12II 650W model that is Haswell Ready as shown on Seasonic's web site.
