I've used up all the connetors on my 400 watt psu and i want to add about 5 fans to my case all that use 4 pin connectors so i want to use an old 300 watt psu i have laying around just to power the fans, so i dont have to to use a splitter to give me more connectors and maybe damage my 400 psu ,my question is how do i rig up the 300 watt psu so that when i turn on my computer both psu's fire up?
thanks in advance

If your second psu is an ATX one, check at http://www.burningissues.net/how_to/power/psu.htm and it shows you how to do it. I've never tried it but it dosen't look that complicated.

I used this method and replaced the relay with a RadioShack mini unit Part# 900-2327 which they may or may not have in stock, but can be ordered. I would give the link for the method I used but it's a dead link, still based on the link above.
