I would first consider to employ some power saving features using e.g. Rain.
Also how about a Geforce2 MX400 as graphics card?

You can try to reduce the Vcore, maybe also the multiplier of the CPU. Try running 7.5x133MHz with reduced Vcore instead of 12x100MHz.

Stuff from this era just wasn't very power efficient, especially Socket A.

Yeah, undervolting should work, though I suspect this will save a few watts at most.

Considering the temperature of both chipsets I would say it will require same power to run, wouldn't it? But it's a good try anyway. 😀

I think too that maybe to go down to 1000 mhz and some 0.x volts less will save who knows, maybe 10W.
Probably switching to the 370 socket would be better, I have a Celeron Tualatin config to build but I never really liked it.

Not to mention fan noise...they seems like my car fan. I reduced the voltage of both the cpu and chipset one risking high temps but saving my ears. 😁

And what about a Barton 3200+ running at 100x11? I think the A7N8X could run in this mode but never tried on the A7V133. I could benefit the lower process and bigger cache.

Some of the lower end Thoroughbred chips use under 50 watts, the 1600+ and 1700+ models to be exact.

As Aideka says Thoroughbred 1600/1700 has a TDP in the low 40s. I recently put one in my MicroATX build to try to bring temps down.
These run at 1.5V and have the advantage of full support in desktop boards, unlike the mobile and embedded processors.
Search for DLT3C to find these on eBay.

90W at the plug actually doesn't seem too bad considering most Athlons have TDP of around 60W just for the CPU.

What about Geode NX1750 ?

Its rated 25W and runs 1400Mhz, also Socket A
(If your Board supply Vcore of 1.25V..)

Finding a desktop board with support for those seems very difficult:

from what I know your MB can run mobile Bartons,

so take a mobile Barton and underclock/undervolt as much as you can? probably the best perf/W for socket A.

Yeah considering how much hot the Duron runs it's not that bad but I get to these only using this video card that usually ran quiet cool. I was thinking to use some very older cards like the Matrox Mystique PCI but maybe I would slow it down too much and if I put some Voodoo2 I will get to the same wattage. The Kyro 2 was probably much faster on the GUI considering it's a 2001 solution. Maybe I could try the Savage 4 or the G450 but the cpu is the point here. I was expecting that the sse duron ran at lower temps.

Well, temperatures are "easily" lowered by using an over the top cooler 😜. Some copper core cooler with support for 8cm fans is all that is needed.

Yeah that's right but for now I'm using a classic XP original heatsink with half fan speed. Temp are always more than 50 celsius degrees.
Now measuring 85 watts during surfing the forum. 😁

Well, if you decide to upgrade the heatsink at some point I have to recommend either Zalman CNPS7000 or GlacialTech SilentBreeze 3, both of which are pretty quiet, and should be enough to cool even the hottest Athlon XP's. I think the Zalman CNPS7700 might also have the mounting hardware for socket a available. The stock heatsinks of those Athlons are not too good in my experience, but the processors themselves seem to cope with exessive heat pretty well.

When the TDP values from the top links are true, then you have ~50watts. Don' t know how much of these values are correct...

Looking at cpu-world, the values for the 0.13micron 1600+ and 1700+ are around 44-45W for the typical power dissipation and up to 50W for the max. power dissipation. Only this SFF version seems to have ~35W.

The Morgan Core with 1200Mhz is almost around 5W higher, that means to recommend a standard XP T-Bred is not really an option.

What makes really sense, is to use a mobile Athlon, with 25W or 35W TDP. But here is the question if the mainboard supports these CPUs...

I've used A7V133 and A7V boards extensively years ago. Afaik CPU support depended a lot on the specific revision of the board (at the time I used these boards, 1.05 seemed to be considered a turning point for Palomino, which is still a 0.18 chip). I don't know if there are any tricks to use more modern CPUs in older boards, this could very well be the case since my knowledge on these boards is old as well.

But once these were set up and running, I found them very fast as well, running a Palomino with 1GB SDRAM and Windows XP I think (and some random GF MX I think), but I've also build rigs with this board using ME and less RAM (I got like at least 6 of these boards I think? All for free and they were being tossed out, so I took em all! 😁)

But when it comes to power draw, the best option of that era will probably be Tualatin.

When it comes to power draw, the best option of that era will probably be C3.

True, but 386SX was I think also wanting something with performance roughly similar to his existing rig.
Tualatin has virtually similar performance for about half the power draw of the CPU, but I should've stated power draw vs performance anyway.
