Have been noticing lately that my PSU makes some serious noise

[Kaspar_5]

I have a system sporting the following components:
GTX 760
Intel i5-4570 CPU
2x HDD
1x SSD
2 extra fans + stock cpu cooler

That is all I have in my case that should take power.
The PSU that I have is a 550W Enermax ETA550AWT-M. When I built the system I got the impression that the PSU should not be too powerful so I didnt go for too much watts.

Now the computer is 2 years old and the PSU is getting noisy. I shot some compressed air into it to clean it but the noise did not get much better.

Should I think about buying a new PSU and if so should I get a more powerful one?

550w is plenty for your setup, but I would go to 650w for the future.

So you do think that I should swap the current one out?

If the noise is getting worse I would , plus the SEASONIC is a better PSU.
