Hello,

I recently received a desktop computer, Siemens Nixdorf Scenic Pro D6 - actually is just the case and the motherboard. The motherboard has a power connector like a normal AT board (2 6-pin) but it also has an additional 6-pin connector. Above the 2 normal AT 6-pin connectors it says 5V and above the additional 6-pin connector it says 3.3V.
Since the case came only with the motherboard inside and there was no power supply, I don't know what kind of power supply is adequate for this board so not to destroy it when the computer is started.
Do I need a special designed power supply for this computer or is it possible to use some sort of adapter to power up the system?
The motherboard contains a Pentium Pro processor with VRM, cooler, integrated audio and network chips.

Thank you in advance for any suggestions!

I found this website: https://www.phantom.sannata.org/viewtopic.php?t=14422
On the pictures named "psu""sound_power""cpu""overview" you can see the power supply sticker with brand and model number, also most of the connectors and colors.

It looks like White Yellow and Orange are not where they supposed to go on a regulat AT connector...
Either they use non standard colors or they are really mixed up...

Also based on the orinentation of your picture the upper connector should have 3 ground pins on the left and 3 3.3v pins (purple) on the right.

Many AT PSUs will have the 3.3V plug that looks like third motherboard plug except the wires is two wires in orange (3.3V) and one red 5V, and three wires are black.

Get ATX to AT adapter cable and this PSU with this third plug to meet this needs.

It's a single CPU motherboard. There is a mention on the motherboard about D983 model (see the picture).
