System Half Built Power On Question

[Ryck]

Okay my friend ordered some parts, not all at once.
Here's what he has got so far :
PC Power and Cooling 510 Deluxe Sli
Intel 945 Board
Inter Pentium D 830
2 X 1Gig Sticks of Mushkin DDR2 Green Ram
Zalman 9500LED Heatsink and Fan
Antec Case

Okay I have assembled what he has gotten so far for him, earlier this morning. He calls me and ask me what would happen if he plugged in the power supply and tried to power it on.
I told him I honestly did not know what would happen. I told him he would be better of not trying, I thought there has got to be load on the 5volt rail or something for the power supply to actually allow itself to be powered on? I thought I had heard that somewhere.

Okay so the question would be what would happen. This system has no video card, no drives what so ever. So what would happen if he powers it on. I told him the Power supply would not start and power on the system, would that be correct?

as long as the psu is plugged in and the processor is in and the ram is in it will attempt to start. if the viedo card is not in there then it will start beeping at him. if the heatsink is not on the processor he could fry the processor...but as long as the psu is plugged in to the main board it will turn on if he tries..

is the psu plugged in to the board? then it will try to power the board....

if it's not plugged in then it won't turn on unless there is a wire of some sort running from the green wire to any of the black ones...

He said it does nothing at all. I guess I will have to go check what is going on.

It should try to post, but it won't. If he just plugged in the PSU and turned it on, it shouldn't do anything. Just tell him not to mess with it until its done. It won't post without a video card.

I just went over early this morning before work and looked at it. He told me he rerouted the front panel connectors because he wanted to hide them. They were hidden to begin with!!!
I checked them and he put them back on wrong. I told him that I was going to take the pc home with me and when he gets the parts, I will assemble the rest at my house.
That should solve the problem with him screwing with it.
