I just got a new PSU, an Antec 750W that is an inch longer than my old Dell Bestec PSU. I installed it fine though it was kind of tight. Turn it on and it's making a ticking sound. I take it out and discover the PSU fan is hitting either a wire or cable tie around the wire inside the PSU. I pulled on the cables a bit and the sound went away.

When I put it back in, it ran fine for a while...now the ticking started back up though not as loud. I tried pulling the cables out a bit but its still ticking. I could probably fix it if I took it back out, but every time it starts hitting it! What should I do? I bought it at Newegg.

Thanks!
