Graphics card for OptiPlex 9020 SFF

Jump to solution

I've got an OptiPlex 9020 SFF and am wondering what is the best possible graphics card that can be installed given the following constraints: 

  1. Single slot - due to the PSU being a short distance away from the PCI Express x16 slot 
  2. Length < 17 cm (6.5") - it appears the SFF can only take cards of length upto about 16/17 cm 
  3. Only low profile/half height - due to SFF 
  4. Powered by PCI Express only - due to PSU not having additional power outlets, and PSU is a 255W 90% unit 

I'm considering one of these options: 

Will either of these cards be compatible with my 9020 SFF. Are there other better options I can consider?

I believe only a ASUS EAH5450 SILENT(LP) Radeon HD 5450 is going to work.

This R7 250 would fit but I'm doubtful about the power as the 5450 uses 19W and the R7 250 uses 68W

Thank you for your quick response. 

I'll pass on the Radeon 5450 - I already have that in my desktop (a Dell Zino 410), and its a 'meh' card - good for media, but just average for games. I've also heard that the stock Intel HD Graphics 4600 that I have outperforms it, so there's no upside to using that card. 

Why do you believe the R7 250 would have power issues? I'm happy to have it explained to me that I'm wrong, but my line of thinking was that the R7 250 uses only the PCI Express x16 slot for power (i.e. up to 75W) and doesn't require any 6- or 8-pin power plugs, and the 75W is something that any motherboard should provide per standard.

Low Profile cards by definition are 25w max.

Radeon 5450 = 19W

R7 250 =  68W

Thats why Fanless cards are used because they cannot afford the power for the fan. All sizes of ×4 and ×8 PCI Express cards are allowed a maximum power consumption of 25 W. All half-height cards are initially 10 W; X16 cards may configure themselves as 'high-power' to reach 25 W, while half-height ×1 cards are fixed at 10 W.

Even if you get a Tower You CANNOT USE Double wide cards because they don't Physically fit. Tower X16 Slots are marked 75W and have a 305W power supply not 255W.

Cheers, that was most useful - I wasn't aware of the 25W cap on low profile cards  

I've seen Wikipedia also states the same information: https://en.wikipedia.org/wiki/PCI_Express#Power 

In that case, I'd best stick with the Intel IGP.

I've been digging into the power limitations a little further, and am probably more confused than ever!  

Firstly, according to Wikipedia, the PCI Express specification does state that x16 low profile cards are limited to 25W draw. 

However, on the Dell.com (i.e. US) site, one is able to configure the OptiPlex 9020 SFF itself with an AMD Radeon HD 8570 card. This card has a 66W TDP despite it being low profile. The support manual states that all OptiPlex 9020 SFFs ship with a 255W 90% efficient PSU. 

I've examined my motherboard, but don't see any wattage indications similar to what SpeedStep has posted. 

I know that Dell have bespoke motherboards for their models. So, are they providing additional power to the x16 slot to enable power draw > 25W?

"8570 ddr3, LP, 1 DP 1 DVI"

This is not a pick from anywhere off the shelf card.

It has DDR3 vs GDDR5 ram to save power and is likely underclocked 64% so that it draws 25W or less. Power usage is slightly higher for the GDDR5 card—12 watts under idle and 68 watts at load, compared with 4 watts and 24 watts for the DDR3 version.

Hello SpeedStep,

it is over a year, pls can you update the topic and pick up some new graphics card, which can fit in Dell Optiplex 9020 SFF. PSU is 255w.

Thank you very much

For info, I've installed an AMD Radeon R7 250 card nearly 18 months ago, and have been satisfied with its performance. The specific card I have is this PowerColor model: http://www.amazon.com/gp/product/B00JQU6WQ6
