Why does a power supply lose power over time?
A power supply will drop its ability to supply power over time due to the capacitors aging and drying up. There is little difference in this regard between a expensive power supply and a cheap power supply. However a cheap power supply is very unlikely to be able to supply the power that it claims on the label.
How long does a power supply last?
Solid state electronics should last for a long time. Unfortunately, Power Supplies contain two kinds of components that do have a limited lifetime. The worst is the capacitors. Large capacity capacitors such as the ones you will find in some power supplies contain liquids that can leak - particularly after overheating that deforms the case.
Do power supplies wear out?
I have 5 of them. As previous poster stated, Power Supplies do indeed wear out. That is a reason FOR getting a quality one, not a reason against.
Do power supplies have a lifetime?
Unfortunately, Power Supplies contain two kinds of components that do have a limited lifetime. The worst is the capacitors. Large capacity capacitors such as the ones you will find in some power supplies contain liquids that can leak - particularly after overheating that deforms the case. Visual examination may spot problems.
Does a cheaper power supply age faster?
A cheaper unit will age quicker and may not have been able to do what it claimed from the start. What power supply do you have and what are you planning to have it run? A power supply will drop its ability to supply power over time due to the capacitors aging and drying up.
Why does my PSU not output the maximum capacitance?
So all we have is some capacitor datasheets and someone somewhere concluded that you that means that the PSU itself degrades within time and does not output the maximum capacitance. Wich is just totally wrong. The capacitors don't really have something to do with the max. capacitance - look at for example be quiet Pure Power 10.
[Discussion] Is there any actual empirical evidence for the
Given that PSUs rely on beefy components, degradation to capacitors and transistors can be a real problem. Obviously, better quality components will last longer, which is why some PSUs
Do power supplies lose their wattage over the course of a few
A power supply will drop its ability to supply power over time due to the capacitors aging and drying up. There is little difference in this regard between a expensive power supply
PSU life expectancy / performance degradation
Barring specific hardware malfunction, does PSU performance naturally degrade over time (i.e. become less efficient or less stable in power output)? If so, what's the average
Do PSU's tend to derate as they age? | TechPowerUp Forums
If you have dirty power from the wall, your PSU will last a shorter amount of time than if it were to receive good clean power from a good high-quality uninterruptible power
Do PSU units wear out over time? | Tom's Hardware Forum
The practical effects of not getting quality components and treating them right is that someday sooner than latter your power supply could fail, and I've seen and heard of some
Does a power supply wear out?
Power supplies usually produce a significant amount of heat. Each heating and cooling cycle of the device causes the components of it to stretch a little bit and degrade the
Does a portable outdoor power supply have a life
Due to the aging of the built-in lithium-ion battery, the portable outdoor power supply has a limited life span, but this does not mean that it is completely unusable once it reaches its life span.

How Long Can an Unused PSU Last?
Some modern power supplies that use high frequency switching can get by without transformers, and possibly even without capacitors. If your unit has achieved that level of
