Low Profile Display Card for DELL Optiplex 320

I refer to my previous question below.


I have not yet purchased the graphic card as I decided that it will be better to have display port instead of HDMI port as my LED moniitor supports Display port and DVI.

My main concern is whether the new display card might exceed the power output for my PSU and overheat.

My main use is to play Bluray (BD) media. Currently, my system can play but the video performance is lagging.

Please suggest the model and brand of low profile display card with your rationale.

Thanks in advance for your help!

There are three important advantages to the PCIe graphics card.
1) You reap a massive boost in system performance because you stopped using shared memory.  When the video GPU is accessing ram, the CPU can't and; especially when streaming video is eating huge percentages of the rams bandwidth, the CPU loses in decoding the stream.
2) The 5450 has hardware accelerated H.264 and WMV9 support so it offloads the video renderring from the CPU.  (I was going to switch you to a GeForce 8400 GS; but the 5450 has lower power requirements)
3) You get the ram previously used by the video back for the system to use.

For your stated purpose, that 5450 ought to give the system all it needs to run 1080P HD video as long as you have 2GB of ram (Windows 7 needs it)
So, go shopping: http://www.google.com/products/catalog?hl=en&biw=1146&bih=766&bav=on.2,or.r_gc.r_pw.&wrapid=tlif130191809825010&q=GV-R455HM-512I&um=1&ie=UTF-8&cid=3411624091569935075&sa=X&ei=i7mZTeS3NpP2swOSv9WJAw&ved=0CFwQ8wIwAQ#

AS per the previous post, the ATI HD5450 draws very low power - actually less than the X1300 you have in there at the moment. At peak 3D, the ATI x1300 uses over 30 watts of power.


Conversely, the 5450 only uses 9 watts and even the 5550 only uses 19 watts:


On the basis of the above and based on your PC already having a card requiring more than 30 watts in 3D games etc, I would suggest the 5570 - this will happily support Blu-Ray playback and some gaming too!

Something like this should do:



Davis McCarnOwnerCommented:
That 5570 card uses 39watts per AMD and the limit for the PCI Express slot in the 320 Desktop is 25 watts (with a 280 watt power supply):

The unit, BTW, also has an integrated X300 video.

I will; however, concur that the 5450 would be a good choice as the specs for most cards indicate 18-20 watts.

Which 5450 card has display port?
Rob KnightConsultantCommented:

My apologies - missed the bit about the PCie 25 watt limitation and thought it was an X1300 not the X300.

Anyway, this should do the trick:


It's also passively cooled too.


I'm curious which processor it has...  if you're experiencing lags and it has one of the single core P4/HT CPUs, you might be better off upgrading it to a dual core rather than switching GPUs.

e.g. 3.4GHz Pentium D 945 - http://preview.tinyurl.com/PentiumD945
~$35 - http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180646114978

You can use CPU-Z (http://www.cpuid.com/softwares/cpu-z.html ) to see which CPU it has now, if you're not sure.
It also shows memory speed, BIOS versions and other info.
Jackie ManAuthor Commented:
MY CPU-Z info is as follows:-

Name                  Intel Pentium 4 630
Codename            Prescott
Specification            Intel(R) Pentium(R) 4 CPU 3.00GHz
Package (platform ID)      Socket 775 LGA (0x4)

I am satisified with the speed and it runs smoothly under Windows 7.

So, upgrading GPU should be a better choice.

What do you think?

Thanks for the inputs.

Finally, I added 512 MB ATI Radeon HD 4550 Graphics (Low Profile, 1 DP, 1 DVI) to my Optiplex 320. The new display card is connected to my Dell U2311H monitor via displayport and all HD videos play very smooth now.


The cost of the display card costs US$35 (including delivery) and I brought it from taoboa.com.
