Added another drive-

[Kiggles]

I threw in a DVD-rom drive recently, and I wasn't sure my PSU would handle it well. It's a 350w running two HDDs, CD-R drive, Athlon XP Barton, and a GF6800NU. I was concerned because the +5v was typically at 4.77-4.79. Running, but I didn't think it could support anything else.

Well, one DVD-ROM drive later and the +5v rail is up to 4.85v. Am I missing something, or is this somehow typical?

an optical has an extremely small parasitic draw most of the time,
when you spin it up thats when it will nail you for 2A +12V (24 Watts)
after its spinning it will drop to about a quarter of that
the +5V draw is pretty variable with model from say 0.7 to 1.5V (all of 3.5 to 7.5 Watts)
and though Im not positive Id bet its related to laser burning with a lower state draw for basic reading

in short it should have next to no impact when not actually in action
