Dell XPS 8300 and Radeon R9 380

Any ATX PSU will fit in that case, and TBH even if the cutout was a bit off I would just use a dremel and modify it, but from everything I see the one you picked will work fine. Its a great PSU choice.

Now as for the R9 380 with the stock PSU, you will need to use the adaptors that come with it, it will work, but you're pushing it. Depending how old it is you may run into some stability issues with it, but generally it should work ok.

one thing to look out for with dell is there proprietary bios -- was not that long ago the new gtx 900 cards would not work on xps but dell did come out with a new bios tyo cover them [a-10 I believe ] that gave support for the newer cards

now will it cover the newer AMD cards ?? may best do some extra homework on that

example of what I say above

ok if that's what you want to go with / believe ? seems funny then a bios update resolved weather it was uefi or not ?? don't you think?? cause the uefi did not change on the board its the bios support of cards that did ?? then if so what about other boards with uefi that had no issues at all ? this is why we do custom builds and not prebuilts cause they can be proprietary

I never recommend upgrading prebuilts anyway its all your own risk ..

my disclaimer

some models of store bought computers [dell.hp,acer,ect..] may come with a ''locked or fixed'' bios and may not allow you to change certain hardware as a video card.. this is done to protect them from undue warranty claims and refunds .this is not done to hurt you but to protect them. you really need to see if that upgrade has been proven to work in your model first before you invest money in it .. there are a lot of these threads here at toms to look at some models will allow upgrades and some dont.. and a lot of guys here say ya ya ya when is really no no no...it would be sad you spent $200 on a card that wount post after you installed it as most find out. then get told its your psu and you spend more and end up right back where you are now, but its up to you good luck..


you got to know the the boards in these computers are not like the ones we use to do custom builds witch are open to upgrading with in the boards compatibly . the bios is custom made for there design and just for the parts they authorize to be used on there computers there only guaranteed to work as is out of the box as you bought it ,..


also these boards do not have to meet atx standards and there pci-e slot power may not do the required 75w needed for most higher end cards and can be limited to say 45 or 60w that is all thats needed with the low end factory oem cards that it may of shipped with

''They said that it was most likely that Dell's BIOS is somehow restrictive, and that was the thing that was stopping it from working. However, Dell is not making any further upgrades to their BIOS, and so this situation seems like a dead end.''

Glad it worked out!

sad thing is is something as plug and play as a vid card is you have to look at all this now a days

anyway god deal that it worked out

I know it has been a while, but curious what's model for this card? I found there are at least few R9 380 Nitro on their website.

Is it one of these:

I am thinking it's the second one as the first one doesn't have "Dual bios" as its feature. Can you please confirm?
