Motherboard, CPU, memory, power supply at minimum. Probably want a video card if you actually want POST to complete, otherwise you'll just get beep codes.
I plan to have the video card in, will anything come up on the screen without a CPU or some RAM? I'm going to have to find a speaker, I don't think I got one with my case, its very tiny if it did.
Oh yah, I can't figure out which way to put the Power Switch, Reset Switch, etc on the pins on the motherboard. Does either way work? You know what I mean? The wires coming from the switches and LEDs up front that plug into the motherboard.
There are correct headers for reset, speaker & pwr. You need to make sure that they are in the correct postion. As far as positive and negative I have never paid attension to that.
You need memory and a cpu to show the bios on the screen. If not it will just beep.
So get this, there is this little 4-pin power connecter. I noticed it but thought nothing of it because the 24-pin power connecter had a little 4-pin plug attached to it. I thought it could be used in either spot. Well I got a BTX/ATX PSU, its more BTX based than ATX based, lol. There is a second box of parts in my PSU box, it contains an adapter to make it more ATX based, lol. So when I get home I bet by bottom dollar that once I slap on that adapter and plug that 4-pin power connecter in it will all work just fine, lol.
You learn something new everyday, well.....almost everyday.
I'll update this thread when I get home and try it, I'm soooo excited!!!.
