    Default Help Choosing new PSU

    Hello, I have this kinda old pc that i need to replace psu, i want to get a not too expensive one but that can still decent and hopefully keep it when i decide to upgrade.

    Pc specs are:
    Intel Xeons X3430 (oc to 3.5ghz)
    Nvidia GTX 770
    Asus P7P55 LX As Motherboard
    2 Mechanical hard drive and 1 ssd

    I want to get a 500-550w psu so i can reuse it when i upgrade to something better.
    On amazon IT i can find these psu for my budget:

    Cooler Master MWE 500 White-v2
    Corsair VS550 (the one with white label so the one made by hec?)
    Seasonic S12III 500
    Thermaltake Smart RGB 500w
    EVGA 500 W1, 80+ WHITE 500W
    Antec VP500P Plus EC

    Any help is welcome.
    Thanks

    Out of those only S12III 500 and MWE 500 are at all worth the attention. MWE is DC-DC based, while S12III indy regulated, but latter is full range.

    Thanks for the help, I tried to look up what the benefits are about being full range and i find that can run fine on both 110v and 230v? or i'm wrong?
    Since i live in EU that use 230v shouldn't be an issue for me.
    I know that dc-dc has better effecency but the coolermaster is only 80+ white while the seasonig is bronze what should i prefer in this case?
    Also i read here that people don't like much that seasonic so i should go for the coolermaster?

    Even on 230V grid full range can be handy, if you live in area with frequent browouts, since mains voltage can dip below 200V and that would stress weaker primary side components in case of limited range PSU.

    OTOH DC-DC isn't just about efficiency but also about voltage stability at low loads (even though Seasonic also says it supports C6/C7 so its low load performance is adequate).

    I see.
    What would you personally buy between the two? the price is pratically identical (10 cent cheaper for the seasonic)

    Is not my pc but is for some relative so no clear plan in mind, but probably something that range from a low to mid tier like a possible ryzen 5 5600 and a gtx 3060 as a best

    In that case go with a quality PSU, that's not a PC for a cheap PSU.

    Make it al least a Cooler Master MWE Bronze V2 450W.

    And certainly don't choose a higher wattage lower quality model over this one. So don't go with anyone you named, those are all lesser choices.

    Ok thanks i'll get that one then.
    Will be the wattage enough even factoring the aging the psu will have (since i don't think will upgrade this year since virus etc)

    A good PSU doesn't lose power over the years, that's a myth.
