Hello,

Was advised I will need to utilize an SATA to Molex adaptor to power the video card I seek to upgrade to (8800gt).

However, I am unsure which of these is needed for my system -- a Dimension e521 :

Nippon Labs SATA-FM SATA 15 Pin male to Molex 4 pin female adaptor

or

ABS SATA To Molex Power Adapter

I have been unable to find documentation for my system that leads me to an answer, so if anyone has any experience with this, your feedback would be appreciated.

Also, judging from the pictures alone, I can't quite tell if these are actually just the same type of adaptor, and the difference in the product names ( "SATA-FM 15 pin male to Molex 4 pin female" and "SATA to Molex" ) leaves me unsure whether they are, indeed, the same type of adaptor.
