    You want something with higher +5V currenct capabilitys, wich doesn't go out of spec when pulling a bit more fromn +5V. That limits the options quite a bit, since the A7N8X-E DLX doesn't seem to be one of the newer SOcket A boards that use the +12V CPU connector for the CPU but instead still uses the +5V rail for the CPU...

    For that CPU I'd guess something in the ballpark of about 50W or maybe 75W - wich should be fine with most modern DC-DC units.

    Question PSU

    I'm really leaning towards a SeaSonic SSR-450RM 450W PSU for my old PC. What do you guys think?

    Heres a Newegg link to it..

    https://www.newegg.com/Product/Produ...82E16817151124

    Edit: I like this PSU for it's 20A on the +5V, and it seems that the PSU has a 20+4 plug for the mobo in the pictures (of course I could buy an adapter if it doesn't) Oh and it's Modular, def will help with cable management in the old case!

    ^ Excellent choice, quality PSU with DC-DC regulation that will cope OK with your +5V heavy / +12 light system:



    And it even comes with a Berg connector for the floppy (much to OW's delight ).




    EDIT - BTW you're very lucky that your relic has survived ~15 years without going up in smoke. That 2002 vintage Future Power WIN-400PS is a ticking bomb stuffed full of Fuhjyyu crapacitors. Kill it with fire ASAP before it lays eggs.


    Also while you're at it you should check that the mobo's capacitors at least look OK (none bulging, oozing or leaking).

    I would not say it's excellent. It is true that with his load he won't run into any of the problems the unit has. The series was no huge success, that's why it's already getting EoL'd, AFAIK.

    Lol, Seasonic G-series is already 4,5 years on the market, when Focus launches it's almost 5 years, that's a long time in hardware land. be quiet! Pure Power 9 and 9 CM weren't a succes, they got replaced within a half year and 3/4 year.

    Is and is not. Here it is not sold for close to a year. You mistake old stocks for actual availability so than it would be more like 3 years and something. Which would actually point towards conclusion the demand is not so high and they stay on stock. Well with those chopper-speed fans, no wonder.

    G-Series is a good design with some (fixable) flaws.

    Pure Power 9 was putting lipstick on a pig, i.e., taking poor design and hoping to milk as much as possible out of it.

    How do you fix high fan speed, high ripple and non-working overload protection to the point the rectifiers for that strange semi-synchronnous rectification short?

    How do you fix
    high fan speed,
    Really? That should be pretty obvious for someone with experience with PSUs.

    high ripple
    S12G 550W didn't exceed ATX spec in any of your tests, as long as loads were in spec. G-450 was even praised by c_hegge for having "excellent" ripple suppression. What exactly is there to fix?

    non-working overload protection to the point the rectifiers for that strange semi-synchronnous rectification short?
    Probably should have been configured a bit more strictly then.
