Dell XPS Pinouts? Power connectors?

[TheNuzziNuzz]

Hey there, sorry for the lacking title...So here is the scoop:

I have a dell xps 8700. I installed an SSD and a r9 270x in it, capping prety much all of its capability. So next I decided that my pc's temperatures were getting too hot. So I got a new Thermaltake chaser case. I had succes in transfering all the parts(At least I think so), and then it came to plugging stuff into the motherbord. I was able to connect everything except "F_Pannel" and the "P4" connector to the motherbord. I could't connect the P4 Because the cable wouldn't reach the MB, but the F_pannel is where most my trouble sits. So the dell case connect to F_pannel via one connector, and the new case has many connectors for HDD led, the power LED, reset button, and the power button. So the problem I am having besides connecting the P4 is finding out wich pin coresponds to wich pinhole for the cases front IO. There is no color coordination, and I have had no luck finding the motherord manual. PLEASE NOTE: I need to know what orientation (+ & -) each pinhole should be in. I really hope that made sense. So here are some resorces that I have looked through along with some more system specifics.

I have a Dell xps 8700

 

I am planning on calling dell support and asking for their support on the matter, if I get anyware, i will edit this post.

 

Thanks for any help any of you can provide! If you have any more questions, just ask!

If it doesn't work it may be a while before I can post/repost again

For LED's it isnt a problem if you reverse the polarity, LED does not short anything out, infact, if reverse biased, it blocks current.

Switch polarity does not matter too.

If an LED does not work, just flip the connector.

pictures are worth a 1000 words in this case..

P4 needs and extension:

panel connections are case related. since moving to the chaser case, the

panel connections are not proprietary (dell thing), but most motherboards

are able to separate the connections (power, pwr LED, HDD LED, reset

a picture of this area is worthy).

Im sorry, I don't think i understand

I'm sorry, I don't think I understood what you said in the second half there. One of the things I am asking tho is what pins do i connect the cases pinholes too? I can't seem to find any instruction on that...

 

Also, Did you say that it doesn't matter if you get positieve and negative polaritys mixed up? and if so, for both the LED's and the Power button?

 

Ultamatly, i just want to make sure i'm not about to short my bord as soon as I plug my machine in. P4 connector wise, where I am today is sunday and most stores are closed. I was kinda hopping I could get my rig back up and running today. Is it not worth the risk attempting to make a P4 extension?

[airdeano]

hence the picture ask.. we don't know either..

 

only the LED (pwr and HDD) are polarity sensitive) the pwr and reset are just

continuity switches.

 

the CPU power is keyed as it will only connect in one direction (non-damaging).

So could I potentially damage any parts by mixing up the polarity? And I think I may have found the name of my MB. I will edit this response later with all the possible modle numbers that I found. Also, I think I mentioned this before, but I retraced the wire placement of the f_pannel pins from the previous case and am going to try and use that placement, the only problem is again, I don't know the polarity.

[TheNuzziNuzz]

Alright, I think I have everything working and the problem solved. Today I was able to turn on my computer. For other people having this issue. It really was just trial and error. You have to play around. Like said in a prevous post, mixing the polarity won't any harm. Anyway, here is the diagram that worked for me on my Dell Xps 8700

 

[] [] [P] [A+] [A-]

[]    [P] [b+] [b-]

 

+=Positive polarity

-=Negative Polarity

P=Power (Polarity Doesn't matter)

B=Pwr Led

A=HDD Led

 

If the above polaritys Don't work, jsut try flipping them. I havn't tried the reset button, so if anyone else out there is able to hook that up too please post what you did!

 

Anyway, thanks for the help guys!

This is an old topic but if anyone is still interested...

On the dell forums, user rdunnill provided a graphic for the FP pinouts for the XPS 8300/8500/8700. I did make a few corrections to it since the PWR BTN polarity was incorrect and added RST pins.
