Power supply ticking/clicking

[Grouchy187]

Some times when I play games, I start to hear a ticking/clicking from my pc. I originally thought this was caused by my hard drive, but I have since then put a different hard drive in and my pc still makes the noise.

I normally keep my pc in a desk cabenit, not closed, so it is hard to hear where the noise comes from. When I put it somewhere else I can't seem to recreate the noise to help identify the location but I think its the psu.

Anyway its a corsair tx750 and here's a short vid of the sound...

Any ideas based on the sound? It appears to be happenning after playing games for a bit, anyone know of a intensive program that might cause it to flare up (that way I could better identify the part, maybe rma it, all should be under warrenty)

Looks like the fan is touching the PSU case. You can check it outside the PC with a short on the green and any black wire:

Plug the PSU into the wall only after you make the short and don't touch the wire.

I cannot get the sound to start up now that I have the PC in an open area... Maybe its because the cabinet forces the air pushed out by fans into the psu exhaust area? I did dust out the pc roughly around the time it start, might have pushed it further back then I usually had it...?

Probably. Check if you can see dust inside the PSU. Use a vacuum cleaner if you do.
