This is my specs
Lenovo ThinkCentre Mt-M 3421A16
Intel(R) Core(TM) i5 CPU 650 @ 3.20GHz
4.00 GB RAM
Win 7 Ultimate
Can a lenovo 280W power supply work with I5 650 3.2 ghz (1stgen) and Palit 750 TI?

NVidia specs for that video card and all the other parts of the computer they spec a 300 watt power supply minimum…
So a 280 watt power supply is really scary…

That setup without the 750 Ti would require 147 W. With the 750 Ti, that requirement would go upto 208W. Now that's just with the list of components that you listed, which didn't include the hard drive or DVD drives, etc. I think it should work out just well enough to get by.
