XPS 8500, video card, power supply, upgrades

Can anyone confirm if this card works? www.amazon.com/.../ref=ox_sc_sfl_title_1;psc=1&smid=ATVPDKIKX0DER

Thanks for the advice! 

Just installed the  GTX 970 G1 with a 750W psu (corsair cx750), worked like a charm. 

The psu is huge but it did fit on the xps 8500 case with some work.  

Wow, Corsair site says that the CX750 is only 5.5in or 140mm long, but it almost looks tighter than my EVGA (which was 165mm).  Maybe it's the shadows in your picture.  

Either way - Good find on another 750w PSU that fits:

(It kind'a makes me wonder how I got one 15mm longer in the case!)

KOEVEN,

Did you leave secure boot enabled?  I am about to do the same upgrade from a GTX660 (with UEFI bios upgrade and secure boot) and would prefer to not disable secure boot.

Did anyone else install a GTX970 with secure boot enabled as well?

Secure boot only works when the card has a certificate in bios and said card did not exist at the time of the machine being made.The same is true for Drivers that do not pass whql. Legacy is removed altogether with UEFI Class 3 bios.

This is interesting.. . Thou I'm through upgrading my 435, it's a point of interest if I change the OS & switch around video cards. I do own a 970 card but it's in another machine. Humm. A new 970 is in the company in-box. Maybe I'll upgrade the 435 at the secretary's desk. Give the old gal something to be buzzed about. Hmm, I guess I can screw around later and check it out. I've got several pcie 2 & 3 sitting around. Nice. My days are planned. Thanks!

I am running in Secure boot mode with a GTX 660 which did not exist when the Bios or computer was made.  

I do not believe there is a certificate for every individual card, but instead certificates for families of cards.  I will update thread after I get the GTX 970 up and running with my results.

The UEFI certificate architechture in UEFI is not a 1 for 1 relationship.  It is setup like a CA with trusted root authorities.  The XPS 8500 contains a root certificate for EVGA (Dell shipped with a EVGA OEM card).  The presence of this root certificate allows EVGA cards containing a UEFI compatible bios that was signed by the root to boot in secure boot.  This is why my GTX 660 works.

Hope this makes sense.  

I will validate if the EVGA GTX 970 was signed with the same root certificate.

Compatible:  Yes!!!!!

Original card with system that worked:  AMD Radeon HD 7770

Additional Info: 

For this card, I recommend you get another case just because the card is so large. It isn't too hard to do an upgrade for the case. You just rewire everything that you wired to begin with. I recommend you watch newegg's part 2 of how to build a PC. The only problem you may have is the front panel connectors because dell doesn't give that info out. I can confirm that the pins will work if following th    diagram.

You cannot press and hold the power button to use the diagram though. The reset button does work.

That's interesting. I had to deal with this i/o problem with several other Dell machines. I take pictures and (find some way to) color code the wires to the i/o slots before I take a Dell motherboard out. Was sort of a task looking for a schematic and ended by one test after another.

With some models, Dell doesn't provide bios updates after a it quits selling. ? Not sure if that's their selling strategy or not. Dell prioritizes certain things that make it  exclusively Dell. They'll never say it.

Manufacturers do that every once in a while. In a competitive market, whether its cars, computers or whatever, the main business is selling you a car or computer, not repairing or spare parts. So making them irreparable or difficult to repair and inexpensive to buy takes presidents.

When I need a board, I usually replace them with something like an Asus or Gigabyte board, start from scratch with software. The good thing about PCs; if it's ATX, it's ATX. The engine mounts are the same.

 Dell prioritizes certain things that make it excusively Dell. 

Ok so here is the update for the XPS 8500.

The reference card for the 970 is finally out.  You can get it at BestBuy.  There aren't many cable management options in this case so the best thing to do is to stuff the excess cables in the second optical drive slot.  The reference design helps keep everything cool because it blows all the hot air directly out the back.  Would recommend.
