Solved!
Go to SolutionUpgrade Newbie Question
I have a Optiplex 390 and I need to upgrade the videocard. I am visually handicapped and need this upgrade to run some special software correctly. Someone has recommended the
GeForce GTX 650 Ti 2GB GDDR5 PCI Express. I am a little nervous about getting into the guts of this machine but I noticed that it required 400 watts. Looking at the online manual it says this unit only has 25 watts..Am I missing something. I think this card should just plug in.
I am a bit of a newbie to the upgrading world but not to computers. Any help would be just super :)
I'd suggest a 7750-based video card, as it should be compatible with the existing power supply.
Here's one on sale: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127709

Hi Heymate,
Your computer will support any PCI Express x16 graphics card and the system comes with 265Watt power supply (PSU). So while purchasing the graphics card you will need to upgrade the PSU on the system.
