The electrican said he would cut the end of the cord i was supplied by evga and attach the 220v plug...is this safe I DONT WANNA BURRN DOWN MY HOUSE ..thanks all
The best would be to buy the cable directly (it's standard, look at the image).
If the cutting/attaching is done by an electrician, he knows what he's doing, it's safe.

Sure it's safe as long as the connections are good. As a bonus, it's only half the current so there should be less heating.
