Pretty sure it doesn't. If you thought of that because of that 40A rail on the PSU, it ain't even close to that 🤣. It has a 30A part from what I remember when recapping it, and the 12v should be a 20A rectifier if my memory serves me right.
I mean the Duron and Sempron were basically the Celerons of AMD's Socket 462 line, more or less. The Duron is basically as low power as a Celeron in terms of TDP.

I'll definitely try a 1800 if I ever find one out in the wild. IIRC the K7VZA 3.0 does support some Athlon XPs as well, if I remember correctly (T-Bred A and B, as well as Palominos).
Not really its just that I know that Athlon XP (Especially Barton class 3000+/3200+)likes to have a decent amperage on the +5v rail and since Duron essentially runs on the same platform I was curious if it too likes a heavy +5v rail. Its nice to know it doesnt need one and is happy enough with a more normal delivery.
I have an unlocked Barton 3200+that was picky about the PSU I tried to run it with, ended up using a 600watt Chinesium PSU that has 35 amps on the +5v rail and it seems happy enough with it, its also got a -5v rail too ...so if I ever find a 462 board with an ISA slot it could in theory run ISA sound cards that need the -5v rail.
Duron should be somewhat lighter on the 5v line, kinda similar to how a lower clocked Athlon XP would also have somewhat lower TDP.
I remember back when we were building higher end Thunderbird systems (1100 to 1400 MHz or so), we'd sometimes have weird stability issues which could be fixed by swapping out the (on paper sufficiently powered on the 5v line) PSU with a PSU with wayyy over the top amperages on 5v. For any 1400MHz Thunderbird we'd want at least 30A if only because we knew it would at least plug that potential hole of stability issues (because getting those early ASUS A7V and A7V133 boards stable enough for our tastes was a challenge in itself and the more potential issues you could prevent, the less we had to go through if any stability issues would emerge).
I found that using a PSU with mediocre amps on the 5v line would often lead to odd stability issues like for instance intermittent BSoD's and often unreproducable system hangs, even with PSUs that should have strong enough 5v lines on paper. Since then I've always used at least 30A-on-the-5v-line good quality PSU (for that time) for any sA system except the lowest clocked ones which I did trust putting a 25A unit in there (think 900MHz Thunderbird or so).
