Ticking Noise on PSU

Solution
If it's a very rapid tick it might be some small thing being hit by fan blades as it rotates. Does the sound match the speed of the fan? If so, you may have to open the PSU case to find and move the part before it is damaged. BUT that may void your warranty, so think carefully before proceeding.
