-What size capacitors should I use?
-What voltage should they be rated?
-Should I use polymer or electrolytic?
For +12V rail, cap's positive on yellow +12V wire, cap's negative on black ground wire. For +5V rail, cap's positive on red +5V wire, cap's negative on black ground. & so on.Originally Posted by superrobowizard
-How should they be installed? bridging the negative and positive?
You aren't and I will not.
so, I still think that adding caps won't solve your probleman array of mostly polymer capacitors. Take note, you folks who think polymers are the answer to all ripple problems... we still got 90mV on 12V2 with these. It ain't all about the caps, people

... Would it be bad to get a capacitor rated at above 16V? Would it fry my hardware, or just be a bit overkill?
Nope, those are Nichicon VZ, that series is not low ESR.
Chemicon LXV should cut it. But notice how the 16V 3300uF Panny FM is half the ESR of the 16V 3300uF Chemicon LXV (0.012 vs 0.024 Ω). The lower the ESR, the better.
