Graphic Card for HD

Iconic

I have just tried to fit my new card, the Sapphire HD5450, and the Shuttle does not recognize it. It will not even boot up! Luckily if I refit the old card (Radeon X300) the computer boots and loads Vista with no problems. A quick google seems to indicate this might be a common problem with some graphic cards. However most of the problems seem to occur when fitting a new card after using the mobo for onboard graphics. A couple of other solutions were uninstalling the previous drivers or replacing the coms battery but I don't think my problem will be solved with either of these solutions.

Has anyone got any further ideas?

Not even booting is unusual.

Does the computer power up with no display?

Or just not do anything at all?


You should at the very least be able to access the bios assuming you are getting a video output from the card at all

In a thread weeks ago I cautioned you that the SFF PSU may not be be capable of running the new video card. Whilst the draw on the HD5450 is low and indeed is designed for SFF use its still a minimum of 400W.

What spec is your PSU ?

A less efficient radeon 9550 loads up on my old crappy 200w SFF psu.

See what happens if you remove the hard drive and dvd drive. The 5450 uses just over 6w of power idle, and only 18w under full load, so I'd be very surprised if it was due to insufficient power

Yes it powers up with no display. Don't know if it means anything but the CD drive also light up. Of course I am now going to use a HDMI connection instead of DVI. When it didn't work I also tried the DVI connection but that didn't work either

Don't know what figures you need but it seems to be an ENG Switching Power Supply Model number AM630BS20S.
AC Input 115Vac-230Vac Current 4A/2A Frequency 47Hz - 63HZ

Total Output Wattage 200W

I assume I have a crappy 200w SFF psu as well if the figures I gave
Richie-from-the-Boro are correct. Should I still remove the drives?

Hmmm, that is low, I'd hold off throwing money at a larger PSU however since you got power to the system.

Unplugging the drives may help if power is the issue, but I'm not certain it is. If that does solve the problem, and you can load bios without them that's probably your issue.

Otherwise, can you test the new GPU in another machine? It may be faulty.

What ' jaydeeuk1 ' was suggesting was to pull any device that draws power, in order to make available what's left to be used by the new video card. However to get into the BIOS is easy, stick you old card in and make any changes with that ... then change the card back to the new one.

I understood from your old post [ I have not re-read it ] that your x300 was a PCIe [ and not an onboard ] so I'm not sure what you would want to change in the BIOS

I'm not saying you have a crappy 200W, the PSU's fitted by Shuttle were more than capable of a sustained output greater than many cheap 350W units were capable of. I just questioned the wisdom of buying any video card without first knowing in advance of purchase, that that particular brand / model would run in your particular SFF.

Let us know how you get on !

Many thanks for the further replies.

I understand that removing the drives would give the video card more power and that would confirm the problem was with the PSU. It appears to be either that or a faulty GPU.

If I eliminate the faulty GPU option first. I have a computer that has onboard graphics with a spare slot. Is there anything I should check or do before I try this option?
