Default Strange psu with a 12,8A rail

Hi, new in here and searching for some advise.

I'm typing this in my sister old compaq Evo machine, who is in urgent need of an upgrade. The 1,5 willamette + 384Mb of pc133 sdram + nvidia vanta can't cope with her actual basic needs.


I was hoping the psu could deal with a 780g micro atx board + 4850e and 2 gb of ram and I opened the box to check the non atx format psu sticker:

Compaq series PDP116P , model PS-7231-6CF (I guess CF has nothing to do with crossfire ready )

5V -->11A
3,3V -->17A
12V -->5A
-12V -->0,15A
12,8V -->7,5A
5,05V AUX-->1,7A
3,3V AUX --> 2,2A

After reading all that I suppose I will have to shrink the component budget in order to include a new case and psu or do I have a remote possibility of not blowing anything if I install a modern board?

Thanks for your help

5A on the +12V rail? A 12.8V rail? 5V AUX? 3.3V AUX?

It wouldn't work on anything but what it's already running. It's utterly proprietary. You're going to need a new case and PSU.

Bsod, I've got one of those exact same PSU's that came with a Compaq. It's got the 12.8V rail. I believe the CPU is an AMD XP 1700+.
