    Default Brand new 8yo Corsair HX 850

    Few months ago, checking old boxes with stuff, I found an unopened Corsair HX 850. At some point I was steadily buying parts for a new rig but afair went for gaming laptop and forgot about that beutiful PSU laying around.

    Anyway, I'm in the process of building a rig atm, 400W tops (i3 8350k, RTX 2060) and would like to ask, is there any reason not to use this PSU? Or anything to be wary of if not? It's 6 - 8 years old, not sure exactly, my youth is a blur heh.

    I ask because I saw opinions online that it's bad to leave PSU unused, capacitor aging, current leakage, deterioration, weathering, corrosion, erosion, cracks, horror, pain and death.

    Thanks in advance.

    No, caps degrade and things change.
    The old HX is not a good PSU and might cause you problems.
    At best some annoying noise coming from the PSU.
    At worst some random reboots/shutdowns.

    Capacitors can degrade faster when not in use than in use, but I'd use it if I were you; but that's just me, not saying the Payne is wrong.

    For the csps.
    connect the psu to the computer and grid for one day without turn on the computer.
    open the computer for one day in idle.
    one day not heavy use.

    It's CP-9020032-EU. Also says "Corsair Components 2011" on the box so I guess 2011.

    Btw I think it's still under warranty, Corsair prolonged it from 7 to 10 years for this model among others (if I got this right).

    Ok. CP part number isn't THAT old. The really old ones had part numbers that start with CMPSU.

    He's being dramatic. Assuming it was the really old HX, it would not be a good PSU by today's standards. 10 years ago, it was fine.

    Naa, just lazy, as always...
    Or forgetting the important part...

    Seems to be a double forward unit though, PUQ-G:

    You did.
    At the time it was a decent PSU.
    But PSU don't get better or age well.

    So I'm NOT saying that it was shit then, I'm saying that its not a good unit for modern systems and components/today because of its age...
    With capacitors that were used (according to jon, they have a burn in test in the factory), that then were in store for almost a decade, its a problem.
    Because you need to "reform" the capacitors after a good amount in storage.
