Ok,ill tray it,but just for knowage,what is c6,c7 stat mean,and why most psu does not suppert it?
The C6 & C7 are sleep states that Intel's new Haswell CPUs intorduced. The idea was for the computer to go into a deeper sleep state that uses even less power then earlier sleep states. The problem is most power supplies were not ready for this new sleep state so when the system dropped to this new lower state the power supply thought the system had turned off not gone to sleep, so they won't wake up with a simple keystroke as before.
You can't expect power supply manufacturers and computer resellers just to throw their existing stock away over this issue. Just turn off in Bios or add a case fan, problem solved.
