so there is a chance that I can buy one of there 3090 OEM MSI GPUs as a single unit it just depends on the stock and when they put them online?

M8HMD Nvidia/MSI RTX 3090, 24GB for R10 and R12

Dell OEM MSI GeForce RTX 3090

Part number = M8HMD
Platforms = Aurora R12/R11/R10
Card dimensions = Length: 267mm, Height: 114mm, Width: 50mm
Maximum Power Consumption = 350W
Power connectors = Two PCIe 8 pin
Ports = Three DisplayPort 1.4a, one HDMI 2.1
Memory = Type: GDDR6X, Size: 24GB, Interface width: 384 bits
Graphics bus = PCIe speed 4.0, PCIe width x16
GPU = Nvidia CUDA cores: 10496, Base clock: 1.39 GHz, Boost clock: 1.69 GHz

this keeps changing.  initially they only sell to Dell pc buyers.  later on they sell some but all depends on stock info.

Thanks for the reply, my question was more on the line if they sell these GPUs independently for consumers to buy themselves without having to do so by purchasing the prebuilt specifications. 

it is a very slight chance, as Dell-Chris M said recently on 2/22/22 "The OEM RTX 3090 part number 869P4 does show as "not for sale" as a stand alone purchase. Why, because any that we do get from the manufacturer first go to whole system (Aurora R13, Aurora R14, XPS 8950) purchases in the queue."

I do not know the difference between the two oem 3090: Dell 869P4 for XPS88950/R13 and M8HMD for R12/11/10.  I can try to find out and post in community later.

The former is very new that you cannot buy it as part, the latter may have a better chance as Dell is liquidating the stock of R12/11/10 and may have surplus of gpu at some point but no guarantee.

Dell-Chris M also said this in 2020 "Dell doesn't sell its custom card
both the 4Y12V Dell/MSI RTX 3080 and M8HMD Dell/MSI RTX 3090 both state For Sale: NO in the SPMD (Spare Parts Master Database)."

They are incorrect about our external sales site selling our OEM video cards. Out there we sell retail video cards MSI, EVGA, etc.

If you have the Dell 5 digit part number for the OEM video card, example = (M8HMD = OEM MSI Nvidia GeForce RTX 3090 24GB GDDR6X, 1.70GHz, Dual fans, DP/DP/DP/HDMI, Aurora R10/11/12
MSI vendor ID = 602-V388-03S
)

You call Dell Spare Parts (USA 1-800-357-3355) and provide the 5 digit OEM part number and ask if it is available for sell.

M8HMD = OEM MSI Nvidia GeForce RTX 3090 24GB GDDR6X, 1.70GHz, Dual fans, DP/DP/DP/HDMI, Aurora R10/11/12
MSI vendor ID = 602-V388-03S

869P4 = OEM MSI Nvidia GeForce RTX 3090 24GB GDDR6X, 1.70GHz, Dual fans, DP/DP/DP/HDMI, Aurora R13/14, XPS 8950
MSI vendor ID = 602-V388D2-14S
