I have a Lenovo K410 (11681DU) -exact model,
and am trying to install an EVGA Nvidia GTX 760.

The power supply for the Lenovo is 280W.
The power requirement for the GTX 760 is 500W.
I also have an E-power 450W external PSU.

My understanding is that a PCI-E x16 can potentially provide 75W to an external component, ie the GPU.
So... would my Lenovo plus my E-power add up to 500W (potentially 525W) or should I just look for a bigger main PSU. And If I should look for something bigger, would 550W be enough or should I go bigger.. (800W)


Note: I am currently running my Lenovo with a GTX 9800, and the E-Power external PSU. I originally bought the external PSU for the GTX 9800 (<-450W requirement), thus the 450 external PSU. ... 50W more... just 50. :pfff:

The 500W number is total for the whole computer when everything is working at it's maximum. The 760 itself only needs 170W of that. Your external should power it but it's going to be close.

If it were mine, I would replace both psu's with something in the 600-700W range. Plenty of power for what you have with room to improve later.
