My system came with a R9 270 which I want to replace with a Sapphire Dual X R9 R280x.
That card needs a 6pin and an 8pin connection and the manufacturer's site say a 500W PSU is advised.
So, I'm concerned that I get a new PSU that fits my case, has the right connectors for all the 8700 components, and is say north of 600W.
Could anyone point me in the right direction.
My system info is......
Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz, 3601 Mhz, 4 Core(s), 8 Logical Processor(s)
Welcome to our community.
We’ll surely try and assist you. To answer your query, XPS 8700 supports the following graphic configuration. The XPS 8700 ships with integrated graphic option, but you can opt to buy a separate discrete graphics card. Following are the options,
Integrated — Intel HD Graphics 4600
Discrete — NVidia GeForce GTX 635, 1GB DDR3 (Optional)
Discrete — NVidia GeForce GTX 660, 1.5GB GDDR5 (Optional)
Discrete — NVidia GeForce GTX 645, 1GB GDDR5 (Optional)
Discrete — NVidia GeForce GTX 650Ti, 2GB GDDR5 (Optional)
Discrete — AMD Radeon HD 7570, 1GB GDDR5 (Optional)
Discrete — AMD Radeon HD 8870 2GB GDDR5 (Optional)
With regards to the PSU, a 460 W power supply is recommended for XPS 8700. Having said this, you can surely try the one you’ve mentioned on the thread. However, we cannot guarantee the performance. Dell has not tested the graphics card and PSU apart from the above listed options for this particular system.
I already have the Sapphire Dual X R9 R280x.
The question is about a PSU that has right connectors for all the 8700 components, a 6pin and an 8pin connection and at least 600W.
has a number of PSU's that were upgraded for those of us that needed more power for high end nVidia cards. The same PSU's will work for the AMD card.
cliff notes: Seasonic X-650, EVGA 650 G2 or EVGA 650 P2 are popular PSUs, will fit the 8700 case and have modular cables that will power that card. The modular cables are almost a must-have in the 8700 case since there is not much room.
I'm not familiar with the AMD cards, however I've heard some put off a fair amount of heat.
I had an issue with an overclocked GTX 770 in an XPS 8700 causing the overall case temps to get too hot so I added a front intake fan. scroll about 1/2 way down this page and you'll see one of the systems where I did this. a front intake, and removing the un-used PCI blanks helped the hot air get out of the case.
A final note, I've not kept up with the AMD cards, but I did read about some cards having issues booting or getting a black screen. I'm not sure if the A10/A11 BIOS updates fixed this or not.
Thanks Dan. I will try one of those.
I AM nervous about getting a 'black screen' but as I have the card already, I can fire ahead with a new PSU, and think about swapping the card later if I run into problems.
Sorry, I just haven't kept up with which AMD cards work or not.
I would search the forums. copy / past the line below into google...

Or, ask a new question with a title like this:
Sapphire Dual X R9 R280x in an XPS 8700 - will it work?
I think it might grab attention for those that have gone with AMD cards.
I did what you said and found this post, so it doesn't sound like I will have a problem.
Doubt you're still following this topic but found it through a search and figured I'd add my input for anyone else who might consider going a similar route. I recently put a Sapphire's r9 280x Dual-X model into my XPS 8700, which is that card's little brother and it fit just fine. Had to reroute (slightly) a few sata cables but I added 2 extra hard drives to my pc when I got it so I probably had less space to work with than you did. The only thing that really gave me any problems was finding a way to wiggle my new psu with all its wiring into position but even that wasn't too bad.
The comment on the SATA cable is right on. You may need a longer cable to route under the card and still be long enough to get to the HDD / OCC.
I have an 8700 and i bought a EVGA power supply and it fit very well. I had a full sized geforce760 gt. It fit but barely. I recently got 1050ti small version and it fits well to. this have been a very good system and upgrading it myself was very easy.
I want to use my XPS 8920 as a (6 monitor) stock-market trading computer.
I've upgraded the video card to a 6 monitor Radeon card. Now I need a more powerful PSU to handle the screens.
So I purchased a Corsair CS650M 650 watt PSU, BUT to my disappointment I have discovered the Dell Mobo has a ATX style P2 4 pin power connector!
The Corsair PSU does not have a ATX style P2 4 pin power connector.
Does anyone know of a solution here?
I dont mind returning the new Corsair PSU for another one that WILL have a ATX style P2 4 pin power connector
