Strange psu with a 12,8A rail

[bsod]

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.

That´s what I supposed, thank you for the confirmation.

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+.
