I'm on the hunt for a new psu that can do Athlon XPs too. There used to be a modernish Corsair psu model starting with V something but it got discontinued. I saw some unbranded ones on fleabay stating a high 5V rail but their quality could be anything.

There still are some new ones available with 30A on the+5v rail that keep in spec with little 12v usage. I think you could look at the 700W and higher PSU, just to get these amps.

I use one of these with my 8KRA2+:

Here's another that should work.

Could try to look locally cheap old OEM units like FSP 250 - 350w. 5V rail on those usually has 22-28A.

My Supernova 850 has the attached specs

Max output is a bit low.

The CPU tells us nothing about what PSU you want, the motherboard does. Reason being, late socket A straddled the line between 5V boards and 12V boards. Nforce2 boards often used 12V.

To be fair, for +5V system, you can pick PSU with rather anemic specs, but you must be certain that it has OCP protection for that rail set above 150%.

Correct, even 25A of high quality PSU can do 125W and 30A can do 150W.

Question is how much 5V OCP is set on Seasonic PSUs?

Cheers,

Depends. Previously Seasonic had rather strict OCP.

To avoid having to store 10+ cases, i have a bunch of "fixed" configs, plus a test bench where i assemble the other configs when i want to use one.
On this bench, i'm using the same PSU for everything from Socket 7 to S1366 : SilverStone SST-ST1000G https://www.pccasegear.com/products/16483/sil … 0w-gold-st1000g
I bought it 2nd hand for ~45/50€ (but with one missing cable i think)

I never had issues with my AthlonXP3200+/MSI K7N2 (but i don't know if +5/25A is enough at full load)

Like many of the tail end Socket 462 motherboards, the K7N2 has a P4 connector, so a strong +5 isn't important in the way it is with the Socket 462 boards that don't have the P4.
