HOW to tell if my PSU is going

Hello,
I have an HP Pavilion a6623uk I think my PSU could be going as I have noticed that the noise has increased since Wednesday.
Normally I noticed when my pc boots up the noise is loud but it fades away after sometime but now it stays loud and the air coming out of the fan section of my PSU has a reduced capacity. My mini tower has a fan at bottom of the below all the ports at the back and one housed within the PSU two air vents one on the right-side large and a smaller one on the left side.
The psu 300 watts
What do you think could be wrong?
