Voltage ripple in PSU lines
I was thinking about buying a new PSu recently, a Fortron 530W . Thinking about this decision i was pondering the idea how voltage can ripple cause instability in overclocking.
Solution : regulate the lines more. My Dad proposed putting a capacator on the lines to even out the current. I know the Mobos and PSU already have allot of regulators like this but I was thinking allong the lines that more is better. Would this idea help at all? Any ideas on circuits on how to use this Idea? This is a place of innovation so I thought I would ask here. Please comment away.

First, a quantity:
Specs call for max ripple to be at 50 mV, for the +3.3 and 5 volt lines, and 100 mV on the +12. Can't remember what frequency though (Since87 would know). |

Hrmmm... I would imagine that with the price PSU's are going for these days that the inductors are dioded against inductive kickback (kind of a "duh" on my part, but you never know), so in an "ideal" system, you shouldn't have a problem putting caps on the output lines, but I would imagine the precharge and drain times associated with the caps might present a problem, unless you can match them evenly across all the voltage lines. Even then, it might screw with the timing on the RC networks.
