Corsair 780t power button problem

[oldestgregg]

I bought my white 780t case in may and its been working perfectly however the last three days from cold boot the power button has not been turning the computer on. I pressed it 7 or 8 times today before it worked and I'm at a loss to what the problem may be as its been fine up until now. If I turn off the PC now and use it ,it will work with maybe a second delay but from a cold boot its very problematic. IIRC I may of used the reset button to power it this morning. Anyone have any ideas and could it be related to Windows 10 as that's the only element that's changed in the last few month

Update, all the USB ports are still getting power and the mobo lights on but even the mobos power button wasn't firing it up so I changed kettle leads and it seems to of fixed it!
