OK, I feel like a real ***** -- we've been having some issues that I think may be power supply related. I'm trying to see what I've actually got in terms of a power supply, BUT...I can't find my original documentation that would list it (that's bad, I know, I think it's just filed somewhere where I can't lay hands on it), AND I can't seem to find anything on my computer, i.e., Device manager, etc., that identifies the psu by name, wattage, etc. I'm running XP, can't find it under Device manager or anywhere else. I don't want to take the unit apart (yet). Any help is appreciated, thanks.
