    Upgrading a pc, is current psu ok?

    Hi all,

    I have finally got round to upgrading my pc from an old athlon to a ryzen 5 3600. Yay.
    The stuff has just been shipped but I thought I didnt need a new psu.

    Looking at the connectors i think i will.

    Ok, so new mobo is an MSI X470 GAMING PLUS MAX, the manual states the power connectors as
    24 pin - atx power
    8 pin - cpu power 1
    4 pin - cpu power 2

    and my current psu is an EVGA supernova 650 P2, spec states
    24 Pin ATX 1x
    EPS (CPU) 2x 8pin (4+4)

    But looking at it im not sure.

    Any thoughts would be great, thanks.

    Stay safe

    Re: Upgrading a pc, is current psu ok?

    I'm running a 3600 with just a single 4 pin CPU power connector. That should be good for 150W, so your 8 pin EPS connector is actually overkill.

    More to the point, how old is the PSU? You might find it doesn't like modern power management, a modern chip can change how much power it draws very fast. You might well get stability problems with it.

    I would have thought you would be ok, doesn't the second eps split into a 4 pin block?

    Re: Upgrading a pc, is current psu ok?

    Yep you're fine. You don't need 8pin + 4 pin. 4+4 is already more than enough.

    I am running a Ryzen 5 2600 and a GTX1080FE off a Corsair SFX450 450W PSU. 650W is more than enough power.

    Well if it makes you happier the capacitors in PSUs do degrade over the years so it isn't a bad idea to replace anyway if the PSU is as old as it sounds

    It isn't an old PSU:
    https://www.tomshardware.com/uk/revi...pply,4364.html

    It has a 10 year warranty,and at worst will be probably be just 4 to 5 years old.
