Enough Wattage or Not?

Hi folks, will be upgrading a system at the weekend and just need opinions on whether I'll need a new power supply. System will be

i7-2600K, R9 280X, 1x3.5" HDD. All stock.

Current PSU is a Corsair CX430W.

Bit too close to for comfort?

Cheers folks. At the moment it's powering an Athlon II X3 and a GTX 460 but I do have a spare XFX Pro 750W that'll probably end up using instead of selling it.

That Superflower HX550 does look nice though.
