    I never knew there were to types of power supplies. Is there a way to get a 20 pin power supply to fit on a 24 pin motherboard?

    It will fit in there.
    Read the motherboard manual to find out if it will work that way.


    (some of them will work that way)

    Thanks, I tried it and it doesn't work. The motherboard manual doesn't say anything about it either.

    Yeah it will fit, you just end up leaving a square block of 4 pins empty

    Just replace the power supply. If its old enough to only be 20 pin, its probably not up to the current requirements of modern motherboard and video cards even if you hacked it to fit.

    Thanks guys, I was trying to stick it in the middle leaving two empy pins on either side. When I tried putting it on an end leaving 4 pins empty like you said, it works. :bigthumb:

    This is a brand new system and I just bought the parts a couple of weeks ago. Is it good to run it with this PSU or should I return it and get a 24 pin. It's a 350 watt Rosewill PSU. :dunno:

    Well, I wouldn't be too concerned about the 20 vs 24pin, but I would consider getting a better power supply period. I would stick with a name brand such as Antec, Enermax, PC Power and Cooling, or Seasonic. You'll end up with a better power supply that will last longer.

    Thanks. This is just a secondary workstation build so that's why I went cheap on it. My primary rig build will be next month. :bigthumb:

    On the contrary, a "modern" motherboard, like one for a Core 2 Duo processor, will have lower power requirements than their P4 predecessors. I ran a P4 system on a 350W PSU with several drives and a graphics card without any problems. When I bought the parts for my system, the guy at the store warned me that if I got a beefy videocard I might have to upgrade my PSU as well but, otherwise, everything should work out fine.

    So, yeah, your system sounds fine...
