Dell 850 watt modular power supply in a 5676
I have installed an hu850ef-00 850 watt power supply in an Inspiron 5676.
It seems that the socket, or the modular cable may not be a standard 24 pin ATX main connector. I have all the pinouts for the power supply after getting the third one. The first two didn't work.
The current supply is good as far as I can tell. The power supply turns on when the power on pin is grounded while not connected to the motherboard.
I'm looking for the motherboard 24 pin "ATX connector" on the motherboard pinouts.
I have a standard 460 watt PSU back in it, and it's working perfect, But will be adding another video card, and some 18 TB hard drives.
Worst case scenario I can just take out the 460 watt power supply and reverse engineer the pinouts by jumping it on, then circuit testing. I'm trying to avoid having. To do that.
I want to have a power supply that runs cooler, as in more in it's sweet spot.
What is the proper modular main cable for a 5676 Inspiron with a VYXHD motherboard?
What are the "ATX" 24 pin pinouts for a VYXHD 0VYXHD?
I have the Alienware R5 main cable currently.

@redxps630 Hi and thanks. I just saw this. I knew about the jack color coding on the power supply, But it was awesome to get confirmation.
It turns out I needed cables from a few different alienware models to make it work in a 5676 Inspiron.
For example an Area 51 R2 04V2VJ main ATX wire (this does away with the need for the stock ATX 2.0 extension cable used on the 5676), this extension doesn't carry any negative voltages. Specificly the -12 and negative -5 volt wires aren't in this extension,
However the power supply versions I tested had no negative voltages on the respective pins on PSU, And the motherboard in question doesn't require them. But -12 is mainly for ISA and High-end soundcard reference voltages
I used and tested HU850EF-00 for voltages on all pins.
An Area 51 R2 -R? PCIe power cable for the video card,
and a GP6MV from an Alienware Aurora R5 through at least R9 for 4 wire CPU power.
The stock 5676 CPU power extension is required with this cable for it to be properly routed to the motherboard.
I only use NVmE so no need for additional power cables, But if any needs to know part numbers I can help
I got it working about an hour and a half ago. It's way more quiet, and shows better numbers in benchmarks.
The main hiccup I had was that the two 850 watt PSUs I got for it had defects.
These have since been repaired.
Thanks again

yw. Cass-ole: “ProTip: Delta N1WJD is better than Huntkey 48Y6D”. “
*R5 R6 share the 51-R2 power supply but get their own unique cable set
*R5 R6 will have either one of the shown cable versions, paired to Delta N1WJD or Huntkey 48Y6D”

@redxps630 cass-ole really?
I was posting what I found out for anyone else that was reading the thread.
I was in no way implying that you needed me to tell you anything.
You're extremely knowledgable.
I greatly appreciate your answers.
The part numbers requirement I was offering was for anyone else reading this thread that may have questions. Not implying you need any help.
