    I doubt a 12 year warrantee supply would last 12 years at full load 24/7; the manufacturers are gambling on it being run at a lesser load.

    On a side note, a 1000W supply run 24/7 for 12 years would burn well over $10,000 in electricity.

    Its wrong to assume that a PSU with longer warranty is better quality. That doesn't necessarily have to be true.

    You can do varios things:
    a) gamble and hope that most people forget about the PSU or stop using after certain time
    b) finance it with other Products and make the money with other products and pay for the Failure rate that way.

    It doesn't have to be higher quality. It can also be an Accounting/Marketing Stunt!
    Especially with insanely long Warranty Times...

    The mining people would be pushing power supplies to their limit; I wonder what sort of failure rate they see.


    Look at the EVGA warrantee, they exclude such 24/7 use

    https://www.evga.com/warranty/power-supplies/

    "
    Any damages to the components, hardware and/or assembly of the Products including but not limited to damages caused as a result of neglect, abuse, accidents, misuse, or unusual physical, electrical or electromechanical stress (including due to uninterrupted use of the Products, or use of the Products for blockchain processing, cryptocurrency mining, or similar purposes).

    Looks like many Manufacturers exclude mining in their terms.

    That includes, but not limited, to Seasonic and others.

    But contnued use of a product is an expected use, Here is a trace from Lipack with AVX2:

    good points. some lower end psu's ive seen have lasted ages. no doubt due to relatively low power draw. it's the fans that clap out in some cases.

    i'm puzzling over getting a 5yr warranty as cheap as is reasonable to get psu..... but still. having that long warranty is a nice replacement option. imo. assuming they honour the warranty.

    in terms of dollars. my mcscrooge mind seems to be calculating that a 5yr warranty equates to half the value of a 10yr warranty psu. excluding all other factors. like reliability and fan noise. Reliability is the top concern...

    if it proves to be reliable for the warranty period who cares about other factors?

    2 psu's
    550w cx (5yr)92 aud
    550rmx (10yr)139aud.
    i still lean toward the rmx. also higher efficiency.
    550vs 65aud (3yr) - might need 3 of these in a 10 yr period?...or i might not. still, the warranty means a lot to me. it is a company standing by its product. and relying on a product outside of its warranty is a gamble. not to say products dont last beyond their warranty period. often they do.
    i'd give the bitfenix a whirl based on the recommendation but i dont have that option where i am.

    Warrantees can be a hassle; down time and return postage costs.
    I have been known to fix dry solder joints and oil fans on new items
    just to avoid the hassle of return.

    Read someplace that shops make most of their money on the extended
    warrantee, but don't know how true that really is.

    Despite this, I needed a new fridge recently and got one partly based
    on the fact that the compressor was warranted for 10 years.

    I also tend to get Crucial RAM second hand because it has a lifetime
    warrantee, so if it tests bad I can always fall back on the warrantee.

    The great thing about fixing something is that there is a high chance
    that one is attending to a weak point and might be able to replace
    it with something stronger (failing capacitors come to mind).
    Another favorite is when the replacement has been re-engineered
    as the weakness of the old part has been recognized and corrected;
    the end result is that the repaired item can be better than new.
