Some much older PSUs are not capable of delivering low enough power for the new C-states introduced in Haswell and beyond, those PSUs however will be of very poor quality anyway.

I'd say anything after 2013/14 should be perfectly fine for Haswell and beyond - and you wouldn't exactly be buying a 5+ year old PSU now-a-days anyway. So I wouldn't worry about it if I were you.




Obviously newer PSUs won't have any issues powering older CPUs without the extra C-states as well.
