I am having some issues when starting my computer. The PSU fan becomes very noisy. This happens randomly and when it happens, I will just unplug my PSU and then plug it back again. I don't have any issues on my PSU before. Also, there are times that when I turned my PC on, I will need to press the power button twice before it actually turn on. Is this an issue with my PSU or do I need to worry more on possible issues?
It seems to me that your PSU got dirty. Please check it that is it got dirty or not. If it is dirty clean it, make sure clean it only with no smooth cloth not with water. Clean it properly. After that if the fan makes noise, theirs might be some problem with the PSU.
This problem does not necessarily mean that your PSU is faulty. There are other factors that can make the PSU fan noisy, aside from defects. The most common factor is dirt and the positioning of the fan to the rest of the PSU. If it gets too close, it will make noises. The same holds true if it is dirty. If the layer of dirt is too thick, the fan may drag it when it spins, causing the noises. As for the power button not registering the boot-up on the first press is primarily due to the switch not being able to toggle the actual button.Â
This happens the carbon content of the button is chipped or has diminished due to age. This would also explain why sometimes, it registers the press, and sometimes not. It is also possible that the spring-loaded mechanism might have been jammed from the inside, causing the inside switch to be stuck while toggling. The best way to find out is to first test a substitute PSU, and see happens. Also take note of the noises made, if it is buzzing, etc. (like the sound of sparks when plugging electrical appliances).
If your power supply’s cooling fan is starting to become noisy, it can have a big effect on the power supply itself. It can cause heating to the power supply because the cooling fan may no longer rotate at its default speed. There are two ways to fix the problem with the cooling fan. First, you can apply lube on the cooling fan to lessen the noise it creates.

The other way is to simply buy a new cooling fan for your power supply since cooling fans are just cheap to buy. To make sure you are buying the right size for your power supply, you can remove the cooling fan from the power supply. This is probably necessary if you are not using a normal tower CPU.
But if your CPU is the standard tower-type, you no longer need to remove the cooling fan out of the power supply because their power supply has the same built. You just need to buy a new power supply cooling fan like this one from eBay: 120mm 2pin Power Supply Replacement Cooling Fan.
