Psu advice for a build

[jammir]

Rig will be running a oc'ed 3570k @4.5, 16GB ram, 500gb ssd and a gtx980ti all on a asus v gene not planning on adding anymore hardware. What wattage should I be looking at?

The supernova g2 seems good deal but won't work in my sff case as the power supply has a internal plug cable and only work when the plug is horizontal

Really want a modular psu so have fewer unwanted cables.

Sorry it's the Silverstone ft03
