That CCFL already has the inverter built in so you just need to plug it into a Molex (4pin) connector. Raidmax aren't exactly high quality PSU and you don't need 1000W for that build.
This XFX 550W
(Tier 1 Seasonic) will work just fine.
If you really want a 1000W pick this EVGA
(Tier 1 Superflower)
