dell xps 8300 need front panel conmector diagram. wont boot

[emperorbun]

can anyone provide a diagram for front panel connector for dell xps 8300? i just moved the motherboard into a new case ( corsair air 540) and got a new psu. When I try to power the system on, I hear a click towards the back of my case and it doesn't turn on. Also there is an amber light next to the 24 pin main connector.

My old psu boots my computer but right after the starting windows screen, my monitor shuts off but my computer is still on. I live in the U.S, California to be exact and I do not see the the 115 or 230 voltage u are talking about on my old psu

But I do see the 115 and 230 on my new corsair hx 850 psu though.

Well I'm gonna buy a new motherboard and processor and see how it goes. Still not comfortable with the new psu though.

Don't forget new OS as well, or wait.

Let see again a few things.

Why did you get new PSU? Did you upgraded your video card?

Have you tried disconnecting fan controller?

Remove fan controller cables, use old PSU and original XPS components (if you upgraded GPU, use original one) in new case.

If this doesn't work, go to your old XPS case, be very careful, remove your on/off switch with wiring and attach to your motherboard to test only - turn it on, will this work? This is where the problem is, also check your front USB panel from XPS case, you most likely want to remove it as well (to use it on new case) - there is possibility that it prevents you from booting. Dell is notorious with proprietary wiring as well, trust me on this.

As you can see, I moved from original case to Cooler Master, I had some glitches as well, original wiring saved me, so I suspect that this is the case.

So, would you try to fix or you would just get new motherboard, new OS etc....?

Thanks for ur help btw. I have tried the old psu, removed the new fan controller, tried the old video card but it did not work. I have ordered a new os, motherboard, processor. I am going to reuse my old hardrive from the xps 8300 and try to install windows 8 on it.

Well dammit, sorry we couldnt help you more but it is weird that your new psu wont turn on your pc and the old one does, maybe the new psu its shutting down to prevent a s/c , dont really know you could try your new psu on another pc and see what happens.

My new mobo and processor is comming today. I will test it and tell u the results.

Look on the motherboard for silk screen label of the functions:
- HD LED
- PWR SW
- RESET SW
- etc, etc.... (they are almost always there, VERY small print thou....)

Also, look at the motherboard for a part number, once you know that you can google it & usually fine the layout pretty quickly....

--Thanks man! If you look behind the hard drive connector this is a diagram of the front panel connections. Its not right next to the actual front panel its sort of above it and perpendicular to the panel itself.

I just saw bigred840's post and the connector pin-out is there just like he said, although I had to put on my magnifying reading glasses to be able to distinguish it; thanks guys!

These are NOT indicated at the F_PANEL 12-pin connector on the motherboard; only a column of RXXX and CXXX numbers, referencing resistors and capacitors. I need the pin-outs for the connector too; at least the two for the power switch!
