the make and model of the PSU would help us help you, as a solid make PSU like Tagan and Antec should handle it if you arent OC'ing but a generic £20 one might not be up to the job

Antec Sonata II Piano Black Quiet Case - 450W Smart Power PSU

Think we discussed this in another thread? The Smartpower that comes with the Sonata doesn't have as strong a 12V rail as the 8800 would need I think. Antec Smartpower 450W Spec.

EDIT:
I stand corrected - http://www.silentpcreview.com/article260-page1.html bottom of that page. It will power the 8800 which requires 26A on the 12V rail. It might be cutting it thin though.

i am not doubting your knowledge, only other people have tod me that it should be ample....

seen it running a x1900xtx with 7 hard drives and OC'ed cpu also seen it running the 8800GTS no prob on another rig. I highly doubt it could do a 8800gtx though

was worried if it was enough beforehand so i just used the suck it and see method plug it in if it goes bang u need a new one hehe

See above fred - edited my post. I just feel that getting something with a stronger 12V behind it and more watts would be adviseable. There's nothing worse than a system that suffers with powerdowns and struggles when its under load because of the demands its under.
