When do you replace a power supply : r/buildapc
It''s hard to provide a solid answer for your question. I have an old Win98 build with a power supply that is over 20 years old and it is doing fine. I have an old 486 machine with a power supply from the late 80''s that is still running fine. Naturally, these old systems are not left on 24/7 like my modern PC, but they do get used pretty often.
When Should VRLA UPS Batteries Be Replaced?
Typical VRLA batteries in large UPS should be replaced after 5 years; depending on how they test & type of battery, it may be less time. Batteries contained in closed modules or small UPS should be replaced every three years or less. All batteries should be replaced if they test at 80% or less of rated backup time as part of a full discharge test.
Capacitor placement in distribution systems for power loss
Abstract: For compensating reactive power, shunt capacitors are often installed in electrical distribution networks. Consequently, in such systems, power loss reduces, voltageprofile improves and feeder capacity releases. However, finding optimal size and location of capacitors in distribution networks is a complex combinatorial optimisation

how often are bad capacitors responsible for LED monitor failures?
If you suspect any power issues, you really should check the voltage output from the power distribution board first. If the voltage should be 5v and you get within 10% of that range, capacitors are not the issue. Lots of other failure points in TV''s to look for. Led issues, Tcon board, bad mainboard (resolder), power distribution, firmware etc...
