no... that 780ti will draw more then 300W under load... so no.

the Wattage of the PSU doesn't really matter as much as the Amps on the 12V rail of the psu. for an i7 +780ti you should have a 600W-750W psu...

For VGA cards you may be able to use would be a GTX750 and less, and hey I'm sorry your French, have a good one.

the 750ti can work with a 300W psu... if its a GOOD 300W psu. if it's some generic junk it's likely you'll have some trouble, as the 750ti draws a LOT of amps on the 12V rail.

Use pcpartpicker to help pick one out.

I prefer semi-modular.

*Make sure the PSU supports the Haswell C6/C7 low power state.

Seems a little on the weak side perhaps a GTX 750 not the GTX 750 Ti, or maybe a GTX 740.
