Optiplex 755 SFF, Radeon HD 5450 compatibility?


Will this card XFX Radeon HD 5450 1GB DDR3 graphic card in Dell Optiplex 755 SFF work ?

Two questions in particular- My Optiplex has a core2duo cpu, and the standard 275W power supply? Will the above card work with the existing supply?

Another question- what is the version of PCI Express in Dell Optiplex 755 SFF - the version of PCI Express in the XFX Radeon card I want to buy is v2.1. I cannot see the version number in the Dell manual, nor can i see it anywhere near the PCI e slot in the motherboard of my Dell Optiplex 755 SFF PC?

Yours sincerely,

Re: Radeon HD 5450 1GB DDR3 graphic card in Dell Optiplex 75

The TDP for a 5450 is 25W so yes its fine.

Its the same TDP as the 2400XT listed in the spec


The card below is for Desktop or SFF.

You cannot use any card in USFF because it does not have slots.

Specifically DELL HFKYC


 Slightly different name but same spec.
