First of all, I have to say i'm VERY glad I found this site by accident. All praise to google.
I've been reading up on these forums, and I've decided to power my touchscreen via the Monolithic 20-pin connector coming off of my power supply, OR the 4-pin for the P4 mobo's.
I didn't see these covered in other topics, and while the search function is great for generalizations, In a forum with such plentiful posts as this one it would be near impossible to weed out a very specific result that may or may not hold the answer... I tried, and after 2 hours of searching I'm just making a new thread...
First of all, I found the documentation for the 12" Touchscreen I am considering (HERE:
http://cgi.ebay.com/Elo-Touchsystems...QQcmdZViewItem) and the manual I found claims it uses 10 watts of power. Is that it? Is LCD that efficient? I thought the 12" width as opposed to the standard 7" or 8" would call for more power. I figured it would call for a larger PSU for that matter...
Also, about drawing power from the PSU within the mainframe, I assume you guys are talking about splicing the wires from the molex to the external wires leading from the adapter into the back of the monitor, correct? I know it's stupid, but clarification is always nice. It makes sense, being a 12V DC current on both paths, but I want to be completely positive before I mod anything.
EDIT: Wait... I just realized by simply saying MOLEX it was probably implied to use the Hard drive power cable... I thought about it and that is a 12v down that wire... But that leads me to another question. How would wiring the power to the 4-pin P4 connector make a monitor turn on automatically, as opposed to the hard drive connector?? I'm and A+ Computer Hardware Certified Tech and this stuff is still confusing me!
