Re: Dell Vostro 430 Graphics Card Upgrade
Dell has tested Vostro 430 system with following video cards :
- nVidia Geforce GTS240 GT220 GT 310
- AMD Radeon 4350
Though, Dell has not tested this system with GTX 650, based on technical specifications it should work with your system.
As correctly mentioned by you, GTX 650 requires a minimum of 400W power supply. The video card has a max TDP of 64W. I researched on the same and found that few users have successfully tested GTX 650 over 350W power supply. Also, nVidia Geforce GTS 240 have similar power consumption statistics and have higher max TDP as compared to GTX 650. So, GTX 650 should work with your system. However, I would strongly recommend you to go for atleast 400W or 500W PSU, so as to prevent any PSU overload issues.
For installing/replacing parts in system, you may refer to service manual of Vostro 430 Here.
Note : Please follow safety instructions given in manual before installing/replacing parts.
Hope this helps.
