Windows 10: How long to keep computer switched on?

    Hi,

    If we're talking ripple current then we're talking PSU, right ? Often the weakest component in any rig which makes sense as it does take all the inrush current. A well designed PSU uses current limiters and should put out a stable voltage and current. Most residual ripple is HF crud caused by the choppers anywway. Pretty harmless unless you're into wideband high-end audio and then some...

    Personally I believe in UPS's I have 2 business computer running 24/7 and in the last 1o years or so I have had on MB fail and 1 PSU. The MB was less than a year old. the PSU was so old I don't remember when I bought it. I usually upgrade MB and CPU ever 3 to 5 years and buy 1 gen back.
    I have lost one notebook at least to lightning in thunderstorms, it was not on a UPS at the time, I won't let that happen again. I also no longer leave my notebook running when I'm not using it. With SSD's Start up and loading window is a 15 second operation there is no advantage to leaving it running.
    The business computers I do for several reasons

    I would be highly upset if I only got 2-3 years of service out of my electronics that are energized 24/7. I think the above is...ummm....a large percentage of hooey.
    pffft well shouldn't you at least google ?

    Aluminum electrolytic Capacitors load life’s ratings are generally expressed between 1000 and 10000 hours at their rated voltage
    anything beyond that are you being lucky just due to factors stated in document .

    " By de-rating, the life expectancies beyond 15 years can be achieved. When life expectancies exceed 15 years the expected life of the capacitor should be limited to 15 years mainly due to the sealing materials deteriorating over time."

    I stand by my statements. When applied to the home PC environment, 10,000 hour (2-3 year) capacitor life is hooey.

    so bottom line you get 2 ~ 4 years are guaranteed lifetime of a capacitor , then any time above is just subjected to give and take ?
    meh , cheers

    I've always turned my computers off at night and never have I had any sort of issue.

    Yes I was relating all this to PSU's in the main.

    The failure mode of electrolytics used in switching supplies can be insidious. Small value caps often abound, and some are used for really critical processes within the power supply, not just cleaning up the final voltage rails produced. The result of that deterioration can be destructive to the power supply, even though outwardly all is well.

    The point I was trying to make is that these parts do have headline lifetime figures that seem very low, but that when used below their maximum ratings see that lifetime increase dramatically.

    Most of my computers always run 24/7 with even restarts only when updates or other SW demands it. There's nothing that ever broke that could be attributed to non-stop running. On the other hand, even as they are all overclocked to safe, stable maximums, they are always properly (and over)cooled and kept clean. I pay exceptional attention to PSUs and power supply to it. I also put good ground in house wiring with safety equipment at the mains. I shut it down only when I'm leaving home for longer periods, like whole day or longer.

    MY! What a lot has come from a simple question from a non-tecchie! I have a lot to digest indeed.

    Frankly, these days it does not really matter much leaving them on 24/7. The average house has loads of things left on all the time or in standby - tvs, satellite boxes, router etc.
    That's because people are lazy. Too much effort to switch the appliance off and pulling the plug out. Just to prove a point,..people were/are upset because their Xbox console machine does not have a facility in the software that ejects a disc from the hand controller,..they actually have to get up and press the little button on the machine. Oh how inconvenient. lol
