Better PSU for ST20G5?

[uk_sam]

I've got the Shuttle ST20G5 and it seems to be running okay. However I am getting some artifacts runnings Warhammer 40k Dawn of War on the XFX 7900GT. XFX tells me that my 240w Silent X PSU could be at fault as it is rated at 16A on the 12V rail whilst they recommend 25A.

So what options do I have in terms of replacing the PSU that I have already for a more powerful one? Really need some help on this one - cheers.

shuttle have made a 300w unit designed for the G chassis, however i am not sure if the height of the unit would be an issue (i believe it is 80mm high, assuming it is the same size as a 250w unit) also there is the pricetag, around £60 from a cometitor. if you have a larger full atx psu you could try that on the system to see if it is the psu at fault.

Thats a good idea, I never thought about trying a normal PSU just to see if the problem clears up. Cheers for that.
