Thanks for the quick reply! The pinouts were correct and I got it fixed and running again.
For anyone wondering in the future, I purchased a 300W 'Apevia PS-ITX300W Mini-ITX/Flex ATX 300W Power Supply - Black' off amazon for 35$ and it proved more than enough to be a replacement. I could have gotten away with a cheaper PSU with less cables. All you need is a PSU with a modern 'standard' ATX connector and a cpu connector.. or an additional connector with two extra +12V Pins.

hey im in this position now and im wondering if this psu is still working for you. also did you have to modify it or can you just use the 20pin without the +4?

You have to modify the pin-out. The wires that are -12V and -5V on a standard supply (though some no longer have the -5) have to be swapped to +12V. That's the reason for the additional 2 +12V wires -- to insert them in place of the others. The pin-out diagram is still there. Did you look at it?
To just check if the supply is the problem, you can just remove the -5V and -12V and power up without drives. But you need the extra +12V with drives installed. You can also make an adapter and use a standard ATX supply externally to test it.
