I learned that I can buy a Mean-Well RT-85B power supply to replace my Aztec power supply in my Kaypro 2 from 1983 (I have the Kaypro 2 that was a rename of the Kaypro II and uses the full-height single-sided drive mounted horizontally just like the Kaypro II).
I was going to go ahead and purchase one but then I found I already had an unused power supply that may be a suitable replacement. But I don't know enough about power supplies to know for sure, so I am asking here in hopes that someone can give me some guidance.
I ended up with power supply pictured below by accidentally ordering it as a replacement for a power supply for an Acer small form factor I picked up at a surplus store. I clicked the wrong button and ended up with the wrong part. This part was for the models that supply the power to the drives through the motherboard instead of directly from a power connector to the drive. Anyway, I ended up with this supply that I couldn't use. After researching the RT-85B I am wondering it this unused PS may work for me.
This is an FSP220-30FABA. The DC outputs are
+12V 18.0A
+5Vsb 2.5A
-12V 0.3A
and looks like this:
Obviously it does not have the same connection header as the RT-85B and I would have to rewire to make it adapt to the Kaypro.
But what I wanted to know is if this PS will even work? It has +12V, +5V, and -12V just like the RT-85B but the Amps are listed differently. I don't know if this PS has the right specs. Can you help me understand the Amps and how these numbers either do or do not match what I need for the Kaypro?
The RT-85B has these DC outputs:
+12V 3.5A
+5V 8A
-12V 0.5A
Thank you for any help you can give me.
