Hi again.
I am going to add some various fans to my computer (you may have seen my post about my unexpectedly powerful case fan...), but I'm not sure about the power that I can get from the +12v leads.
My power supply is a 400W switchmode ATX PSU. It has the usuall connections. However, I have 2 CD drives and 2 hard disks, so all four of the large drive connectors are used, and one of the small ones (for my floppy drive). Connectors in themselves aren't an issue, I can make adapters, however, the power I can get over one lead is an issue. I have posted the table that is on the side of my PSU. My PSU has five sets of leads coming out of it - standard ATX, auxilarly ATX, 2 HD/floppy (remembering that each HD/Floppy thing has two large and one small drive connector on) and one extra connector (with some orange leads and things...)
in total, therefore, there is 5 yellow (+12v) leads coming out of the PSU. Would these all be connected together inside the PSU? If so, can I load them up until I reach the max current for the 12v supply? Or can each lead take only their 'share' of the total (i.e. total current on 12v divided by 5)?
On one of the HD/Floppy sets of leads, I have 2 cd drives and one floppy drive. If I also connected a couple of fans to this set of leads, so you think this would cause any problems to the drives? (as long as I was not going above the max current). Which brings me onto my next question. How do I know how much current my various drives draw?
Thanks, all info and suggestions appreciated

P.S. If this doesn't make much sense, please tell me, and i will re-write it!! (its getting late...)
