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.

Did you install anything new aside from the case and psu?

the fastest way to know if you have a faulty psu its to use the old psu and see if it turns on correctly.
try removing ram, drives, and cards 1 per 1 till it turns on to check what was the problem.

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....

I installed a molex fan controller along with the new psu and case. There is no diagram on the motherboard to reference.

It should be pretty simple to find one, but first you need to Know the Brand and Model from the Motherboard. To know this please take a look at your motherboard and check for these:

This information might be in diferent places, once you have them you can google it up and you will Find the Motherboard Diagram.

Have you tried removing the the rams or gpu?

btw in that motherboard you have:

1 x 4-pin ATX 12V Power connector
1 x 24-pin ATX Power connector

Have you checked that they are properly pluged in? and disconect the new fan for now.

Have been reading alot about this amber light on dells, it seems its a common problem with them. Most people just buy a new motherboard when this happens.

An amber light in the motherboard means that theres a problem with the power transfer, and because the light its turn on that means the psu its working correctly.
Try using your old psu and see if the problem its still there. Worst Case scenario you are going to end up buying a new motherboard but dont worry that gen its really cheap.

Yeah i didnt get that post i think you wrote it at the same time i answered, weird so your Psu can Boot your Pc but it wont completly turn on? What voltage do you have your psu at? You have 2 options the 115 or the 230 , which one are you using and what country do you live in? Also for checking it really fast, check your old psu in the backside it should show the proper volt, 115 or 230.

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

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.

--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.
