It is here...I have a HP p7-1423w that I bought in December 2012. When you unplug the power cord, the green light on the PSU stays on for a few minutes. In my area, we get frequent power outages for a few minutes at a time...I'm convinced that's what killed my last desktop. With my new computer, it starts normally after every power outage...no safe mode message or anything. It's great. I haven't yet been able to find any literature on this, but I know I have it.
