I have a Dell Optiplex 980 SFF and want to replace the NVidia NVS 420 4 port video card (because I don’t have the adaptor cable and only need one monitor anyway) with a regular video card. (The onboard video does not work because it is an i7 processor).
Does any one know if this DELL part is compatible: Dell PN: XF27T - AMD Radeon HD 5450 512MB PCIe x16 DMS-59 Port Low Profile Video Card.
Thank you in advance
dms59 requires a special video cable
What you want is an ASUS EAH5450.
This is why Single Slot Only and less than 9 inches long is required. The ASUS EAH5450 works fine in all dell models EXCEPT usff which has no slots. Even the TOWER has the 1 Slot wide 8.5 inch Long Limit.
You cant use a THICK card. This is why Dell cards are fanless.
I would recommend a Nvidia 730 card, these are about the fastest upgrade you will get at the moment in the 980 SFF with a 40watt powerdraw which is within spec for that system. Make sure it is single slot and low profile however, such as this card: www.amazon.com/.../B00Q46V738 It may be possible to fit 730 cards with larger heatsinks , however you would need to remove the HDD plastic cover, which could affect system cooling.
The SFF says 25W max for the low profile X16 slot 40W is out of spec and will kill the power supply.
Using cards that take 40W can lead to power supply failure and total death of RAM, CPU, Hard Drive when the Power supply Fails overvoltage and Fries everything.
