PSU failing to wake computer from sleep.

Out of the blue, following behaviour:

  • PC boots out of cold state
  • When I put it to sleep, and try to wake it later, half of the time, I hear a click, the sleep light goes out permanently and it doesn't react to power button presses anymore.
  • I have to fully shut off (with the I/O button) the PSU before I can start my PC again.

Faulty / failing PSU? (A 3 year old Corsair RMX850)

The fact that I can sometimes get it to boot fully and click around in Windows leads me to believe that the actual components are fine, and it's just the power required to wake from sleep that is failing in the PSU?
