compatiability
i have a Lenovo k330b desktop. I wonder if this grahpics car would be compatible with it.
Couldn't find manual on Lenovo site so will require taking cover off to look. From specs, appears that is a Core i3 machine using on-board video. Yes, this will be a significant upgrade. Now, with the cover off, to see if will work...
1) The first two PCI-E slots (from center of computer - not bottom) should be free. You plug into one but physically requires 2 slots. (If occupied - which doubt, would be another video card and your monitor cable comes from it, but will be discarded). This is a long card so make sure has clearance to fit lengthwise.
2) Power Supply. Manufacturers are notorious for putting in barest minimum power supply so may need to upgrade. Card specs state 400w required and should be sufficient on an i3 machine but suggest 600w. Make sure the existing power supply has a spare power line for the card, either 6 or 8 pin, adapters are included.
3) Finally, disable the on-board video. Relatively easy and should have instructions from Lenovo manuals or a support ticket.
