Is my PSU big enough?

[stimike]

Hey guys, upgrading my PC and wondering if my PSU will be strong enough for this:

i7 930 (going to try to OC to 4.2)
Spire TherMax Eclipse II with 2 120mm
Gigabyte GA-X58A-UD3R Motherboard
G.Skill Ripjaw 1.6v DDR3 1600 (6 gigs)
2 320gb Spinpoint F4 in Raid 0
1 500GB WD Blue for backup
1 SATA DVDRW Drive
2 460 GTX EVGA Superclock
7 120mm case fans

All on this PSU:

Corsair 750TX (750w)

It'll be enough. Though I do recommend keeping your OC to just 4Ghz.

Yeah, I'm aiming for 4ghz but if temps allow it, im goin for 4.2
