Hi all,

I have this Compaq D815E. Seems like a very interesting motherboard with support for Tualatin CPUs and also has Intel i752 on-board graphics. Unfortunately it won't power with standard ATX PSU because of different pinout. I did some research but cannot seem to find an exact pinout for this motherboard. Various conflicting information on the internet but nothing seems to match.

Here is the exact motherboard model:

After hours of searching, I think I have pinpointed the system this board was on:

According to the listing, this PSU was inside:
HIPRO HP-D2537F3R

I kindly ask for help on finding correct pinout to create an adapter and use this board with standard ATX Power Supply. Thanks in advance 😀
