PSU switchover issues

  1. Hey guys, I hope someone can help me out, i browsed through the forum but didnt really find an answer to my question.

    I'm trying to add a new power supply to my pc so I bought a 400W (as apposed to my old one 266W) and turns out theres this 3-pin cord creature that sticks right next to the 20(4)-pin cord into the motherboard. Now I know it is used to monitor the fan power supply. But the new PSU i got has a 4-pin cord instead of a 3 pin.

    I've seen some people suggest that its no big deal if I leave it unplugged, but Im not ready to screw up my pc just yet.

    here's how the cord looks like btw:

    the one with blue wires.

    thanks a billion,

    Look for an adaptor at your favorite store. That's just a general answer. I don't entirely understand your 2 cord configs. That blue cord in the pix looks like a normal 3 pin fan plug. Many times thode 4 pin plugs have a way of plugging into the 4 pin outlets. I just looked at your 2nd post and now I'm wondering if you are talking about thr 4 pin female cpu power connector. Need more information or that is, more precise descriptions of all parts involved and what you are trying to do.
