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?
