Graphics card upgrade for dell optiplex 9020 mini tower

Jump to solution

I have a Dell optiplex 9020 mini tower and i would like to put a graphics card in it. As i currently understand it i would need to upgrade the power supple to power a new card. I am currently looking a the Corsair CX500 with a Dell OptiPlex 9020 PSU Main Power 24-Pin to 8-Pin Adapter to allow it to interface with the mother board. The mother board has a free PCI socket. Are there any restrictions to the graphics cards i could put in?

Outside of the actual Dell case I am unaware of any restrictions other than the MODDIY adapter which is REQUIRED because the stock power supply does NOT support a card over 75W.  Standard EPS12v power supplies have 24 pin connector and the motherboard has Dell  connector instead. You also have to use the stock Dell cooler and front panel connections or there will be other errors that prevent POST and BOOT.

HI FeWatts

Thanks for writing to us.

The machines are tested with only one type of power supply at Dell i.e. 290W, with regards to graphics card

AMD, Radeon R5 240, 1GB

NVIDIA, GeForce GTX 645, 1GB

AMD, Radeon R7 250, 2GB

NVIDIA, GeForce GTX 745, 4GB

AMD, Radeon HD8490, 1GB

are compatible.

We see few of our customers who tried to upgrade parts that are not tested by Dell for few it worked but for few it was little to no luck.

Do provide us the system tag# and also confirm the name the system is registered under by

clicking on my name in blue and then select send a private message. Also let us know the contact

number and email address.

The restrictions are based on the Slot length. MODDIY CAB359 is required for new power supply

MINI ITX versions of cards are fine but 10 to 12 inch long cards are not.

 Cards over 75W require EVGA 750 B1 power supply and the MODDIY Adapter.

The graphics card i am looking at is the Sapphire Radeon RX470 4gb version. I don't think it is to long at 9.5 inches, and it's recommended minimum power supply is 450w.

If this is to large would the EVGA NVIDIA GeForce GTX 1050 Ti 4GB SC fit ?

The GTX 970 is a 300w card.   MINI ITX 1050 Ti cards are 75w to 150W.  Cards MUST NOT BE full length or they will NOT go in.

Only 75W or less cards work with stock power supply

This card for example is a 1050TI but WILL NOT FIT.

This card will fit.
