Hello!

I want to change gpu to GTX 650 Ti Boost.
I dont know if my psu will handle it.
it have 12V1 - 14A(168W) + 12V2 - 15A(180W).
Thanks for help!

I recently installed a GTX 650 Ti into my system I upgraded too a EVGA Bronze 600 which handles it beautifully where as you could get away with a 500w just fine. This card required a 6 pin connector from the PSU so make sure what you upgrade to has one.

Thanks for info.
I know that 500W will handle it nice.
But i need to know if my 400W will make the work with this config.

400 watts will not cut it, I think it would be too close to the red line. At minimum Id say 450 Watts but, even that is stretching it.
