That makes sense. A CD drive uses 5v and 12v, so it loads the 5v. But that also takes some power (albeit little) from the 12v line. To help prevent false peaks, adding a couple 4700uF 16v caps may help. The output of these supplies are fairly quiet from switching noise, but PC motherboards have caps all over the place in key areas to help. A cheapie PS might not be as tight.

@mvalentine6: I guess I missed your question. Even though it was posted a while ago: The 5v line is generally rated for a much higher current (usually at least 20A), so unless you plan to run the 5v line to the max, adding loading won't help.
