  1. alright,so right now i have a 250 watt power supply and i want to upgrade to 300 watts. my friend gave me his atx-730 300 watt power supply (made by enhance). I opened up my computer to replace my old power supply and while i was unplugging it i realized that my old power supply has a connection labeled "p7" which is 4 pin connector arranged as a square (2x2). The problem is, the atx-730 doesnt have one of these connectors. I dont know what this connection does or if i should continue without the p7 part. anybody know what i should do?

    If that cable was just 'there' without being connected to the motherboard, don't worry about it.
    It is only needed for Intel P4 CPUs and lately also for AMD64 S939 CPUs to supply extra power to the CPU. A motherboard that requires it would have a matching receptacle for it.

    yeah that 4pin plug is just the ATX 12V connector. Older mobos don't require it.
