I have a Inspiron 660 that I need a new GPU for. I currently have a GTX 750 installed, but the HDMI stopped working, (not enough power?). I have a GTX 650 and 660. Will either of those work? (probably not enough room for the 660). I know that the BIOS needs to be able to work with it. How do I tell if the GPU is compatible? Also, do I need to upgrade my PSU? If so, what would be a good option for that? Can I use full modular? Thank you in advance.
1. you have a Dell Inspiron 660 , I need you to track the dell label and provide the complete "SERVICE TAG"
if the label is unreadable, boot into bios (usually F2 or F10) it should also be registered in the details of hardware information section, this will provide all the motherboard details I will need to suggest a proper cpu upgrade, as for cheap upgrade it may be very possible to purchase on ebay/used store to upgrade this cheaply
2. (deleted this lane as I read GTX 970 not GTX 750.. apologies)
3. once you have provided the service tag of the unit I will be able to identify the more than likely power supply that came with the unit (if it has not been changed before, which leads me to my next request; open the case, the power supply is located at the top of the unit (refer to the picture below it is item no. 1, look for the label on it if visible you should see if factory installed, or aftermarket for model and make of the power supply.
With these 3 things I can further help with upgrade and concerns regarding power.
