adding samsung 960 evo m.2 as boot drive to xps8910se?

The Samsung SSD 960 EVO M.2 will fit and work with the XPS 8910. I installed this SSD in my XPS 8910 a month ago and it works great. It will run at full speed under the PCIe Gen.3 x 4 interface.

I installed Windows 10/Programs to the SSD as a boot drive. I formatted the original 1 TB Seagate HDD and made it a secondary storage drive for general files.

Then I'm totally screwed (pun intended).  Where the heck am I going to get the standoff that separates the card from the motherboard?  Thanks. I guess there is no way I can install this device?

You need to call Dell. I'm sure they have the parts.

I did.   They may have them but won't sell them.  They won't even sell me the screw and never mentioned the standoff piece.  This even though I was going to buy tye M. 2 from them!  They are losing a sale because to lazy or inept to provide necessary pieces.  They suggested buying several sized screws and trying to see what fits.  At least you told be the screw size.   Bottom line is I'd be crazy to attempt this mod without the right parts

I don't know if your system has that standoff piece. When I upgraded mine there was a 32 GB PCIE SSD configured in RAID. There are two holes in the motherboard for a shorter and a longer SSD card and I moved the standoff from the closest to the farthest. You might open your system and see if the standoff is there. It has a screw that attaches to the motherboard and the top has a hole for the M2.0 x 2.5 mm screw. All it does is allow the SSD card to be horizontal to the motherboard when the screw is tightened.

Thanks but since I did not choose the model with the 32 gb m.2 I don't have the screw nor standoff piece in either hole

I found out the problem isn't just the screw. There is a part the screw goes into called a stand off which makes the card sit properly on the board. I can get the screw but the standoff is unique to the motherboard. Dell sales doesn't even know what it is so they won't sell it. If you bought the hybrid drive your motherboard came with screw and matching standoff. Otherwise you are screwed.  I've given up on the idea entirely.

Ask a local PC shop if they can sell (give) you the screw...

I bought my XPS 8910 locally off the shelf from Best Buy. It did not come with a m.2 SSD pre-installed. But the m.2 standoff is already on the motherboard for you to be able to add a m.2 SSD.

All you need is the M2x2.5 screw to attach the m.2 SSD to the motherboard.

I'd have to take the video card out to see right?

When you installed the M.2 did you have to remove the power module and the graphics card?

The power supply swings up. You need to check the manual. I'm pretty sure the graphics card had to be removed as well since the connection for the M.2 SSD is on the motherboard and there is not much access to the motherboard with the video card. Once you get your screw you need to move the standoff so that the notch on the SSD card is over the standoff and you can put in the screw. The biggest problem I had was working with the incredibly tiny screw. A magnetized screwdriver would be a good idea but I can attest that it is possible without. It just falls down and needs to be retrieved. The screw should have a standard Phillips head but you will need to use a very small Phillips screwdriver.

The Power module just needs to be swung out to access and install the M.2 SSD. It is really easy and no tools are required.

Depending on the size of your installed video card, it may need to be removed. If it is a full size video card it will need to be removed.

My XPS 8910 just has a basic Nvidia Geforce GTX 750 Ti which is a small video card, so I did not have to remove it to install the M.2 SSD.

I have a full sized AMD RX480 graphics card.  The manual says to. actually remove the power module (not just move it) It tells u how to unplug it. Then I have to remove graphics card and unplug it. Afgeter all that I may not even have the setback to put the screw in. Dellcares in twitter said you only get it with the preinstalled hybrid drive which I did not buy.   It's just too many things I could screw up.  I give. I'm either going to forget about it or just buy a 2.5 inch ssd and put it in a 3.5 inch adapter and put it in one of the hdd slots. They appear easier to access. I don't mind pulling back th epower cage but I don't want to remove any cards I might break or damage the motherboard. ssd installation looks easier although I know it isn't as fast as the PCLE M.2

Although I've given up I hope this thread helps other novices like me who have the confidence and steady hands necessary for m.2 installation.  Thanks everybody!
