With the Haswell CPUs the power regulator was moved into the CPU itself, and there was a potential problem if the power supply didn't handle the new "very low" power states correctly. Your machine could go into a "rest" state and cause a reboot. Now with this latest generation called Skylake, Intel has moved the power regulator off the CPU again and onto the motherboard. So, does this mean the possible problem is solved? Or do we have to check if any PSU we want to buy is compatible with the power states of the most recent CPUs? If so, how do you check for compatibility of a PSU with the new CPUs?
