I'm looking to buy a new psu as my current one is only 250w.

My build: radeon hd 6770 2gb GPU
asus P8Z77-V LX mobo
16gb crucial ballistix sport ddr3 at 1600 (4x4gb)
i5 ivy bridge at 3.40ghz
2tb hdd

i have about 5 things connected via usb too.

please can you tell me how big of a psu I should get in watts.

thanks.
