Hey everyone, if you are interested, I ended up solving this with some help of a forum member here:

Hey Keith, thanks again.
I looked up those Panasonic OS-CON caps. Seems like 16v is about as good as I can find in 270uF. I suppose that'll be fine for 12v considering it's a computer PSU that is supplying it, therefore it should never really stray near 16v, right?
And what if I didn't care...
Hi Keith,
Thanks so much for the reply and the information. That's really great.
I am going to source some low ESR caps capable of handling higher ripple current and see if that solves the problem.
All the best,
Dax.
Hey gang,
I have tested two different brands of PCI-e riser boards with an audio DSP card containing 8x SHARC 21469 ICs. Both of the risers seem to work perfectly, but their capacitors get too hot to touch within about a minute.
The max current draw for that card is allegedly 8W, which seems...
