Aurora-R4, Intel X79 Mobo/ GPU compatibility
So, i've been doing some research because my graphics card just died. Luckily i had a spare which will allow me to watch netflix..that's pretty much it. I called Dell/Alienware Tech Support to figure out what PCI-E version i can run (2.0/3.0). I had a Radeon 7850 in my PC which was a 3.0, So i assume i can use 3.0 even if it over clocks it. My question: I'm looking at an MSI Radeon 280x, However i can't seem to find a picture of the pin connections for the external power. I want to say i have 16 or 18 pin connections and am curious if the MSI card will run without any issues before i go drop a good portion of my pay check on it.
Alienware Aurora R4, i7 processer, Intel x79 chipset, 8g DDR3 ram, PCI-E slots x2, 1.1 slots x2, Tech support said my PCI-E slots were "Unlocked". However did not specify which version it was made to run.

Thanks! I will check the Power Supply when i get home,
-----P14 (6 pin)
\---P15 (6+2= 8 pin)
-----P16 (6 pin)
\---P17 (6+2= 8 pin)
This portion doesn't make sense to me though, So instead of having the same two wires that were plugged into my Radeon 7850; plugged into the new ones you suggest testing a combination of wires and seeing which ones will work? I'm trying to determine if the 280x will work before i go out and buy it.

Yes, Aurora R4 has Intel x79 chipset
It's mATX motherboard has two PCIe x16 v3.0 slots (also backwards compatible with older v2.0 cards) ... also two x1 slots. IIRC, at least two SATA-3/600 for your SSDs.
It should run any $400 video-card. Single card solution is best (due to power reqs and cooling). Check for the Dell 875watt PowerSupply. Be sure it has the proper-pinned power-plugs natively available for you to use.
My Aurora-R1 has the 875w Power-Supply and is (DPN) OGM34R
-----P14 (6 pin)
\---P15 (6+2= 8 pin)
-----P16 (6 pin)
\---P17 (6+2= 8 pin)
Assuming the power supply wire colors indicate the 12v rails going to the video cards:
Try with a power connector from each wire set at the same time.
Meaning, with a single card ...
use either P14 OR P15
and ALSO
either P16 OR P17

I checked, 875W power supply..i was too lazy to open my PC up after work so i called Alienware tech support and they said i have every single type of power pin in my PC (16/18 and everything below). the gentleman i talked to said i can take any graphics card on the market and run it in my PC (which i affectionately call Big Bertha due to the size). I had a AMD Radeon 7870 in it which after just shy of 4 years died. I can't post the link to the new card for some reason, but it's anMSI R9 280X 2048 Stream Processors 3GB 384-bit GDDR5 Ram PCI Express 3.0.

The card i'm looking at is an MSI R9 - 280X. I can't post a link because it says it's "Media".

I had a AMD Radeon 7870 in there, which finally went out after just short of 4 years.
