The power that a video card requires is more complicated than the information that is often provided by merchants who are selling the card/s, an example of this is the amperage that the card requires to be present on the PSUs +12V rail, I have not been able to find this information anywhere and the information from MSI is also less than helpful.
The card reportedly will run hot due to the fanless design and this heat will soon build up inside your SFF case, the temperatures inside the case will also be increased by a PSU that is working harder than it should to keep up with the power demands placed on it.
Can I ask what the main use of the computer is and what the ambient room temperatures are like where the computer is used.
Some testing for you to do;
Test the card with Valley Benchmark (free) details here
and install it. Once it's installed, run the program and post here the information it shows.
The information I want you to post is the stuff that is circled in the example picture I have attached.
If you are running on a vista machine, please go to where you installed the program and run the program as administrator. (this is a screenshot from a vista machine)
To capture and post a screenshot;
Click on the ALT key + PRT SCR key..its on the top row..right hand side..now click on start...all programs...accessories...paint....left click in the white area ...press CTRL + V...click on file...click on save...save it to your desktop...name it something related to the screen your capturing... BE SURE TO SAVE IT AS A .JPG ...otherwise it may be to big to upload... then after typing in any response you have... click on browse...desktop...find the screenshot..select it and click on the upload button...then on the lower left...after it says upload successful...click on add reply like you normally would.
Depending on the results we may need to run further software for comparison http://www.cpuid.com.../hwmonitor.htmlScreenshot instructions are provided to assist those that may read this topic but are not yet aware of the “how to”.
You are welcome btw
