New to custom building PCs and got a surprise. Can my PSU handle these?

[arcticursa]

Okay so newegg recently sent me an extra AMD Sapphire 280X and I was wondering if I have the power to run two of them in crossfire.

PSU: Antec 750W gaming power supply
CPU: Intel i7 2600k
Motherboard: ASUS p8p67 deluxe
Hard drive: Western Digital 1TB Caviar Black, not sure which since there's like 10 different models on newegg

I'll be watching the thread so let me know if you need more info

i think you will be fine with that 750W PSU
