Quick PSU question

[NE-Hops]

Okay, yesterday I went and bought the Titan Katana, spec'd it with a 290 and 250gb hdd with the intention of adding a HDD later down the road. The 4670K is OC'd to 4.2ghz and I'm pretty sure the MSI 290 is factory OC'd.

Above is the PSU included in the bundle, is it enough or should I swap it for the 650w variant?

I asked in customer service (which is amazing!) and the reply was that it was 'fairly capable' but I could change it if I wanted.

Cheers.

(Sorry if this gets asked a lot, but everyone starts somewhere, right )

You'll be fine with the 550w, I can't see Overclockers selling an overclocked system with an inadequate power supply.. an additional hard drive won't tax it too much

Funny enough a similar question was asked not so long ago http://forums.overclockers.co.uk/showthread.php?t=18603074

As BattFink said, you'll be absolutely fine with the 550W. Especially given that the power supply is of decent quality. ASUS have a minimum wattage calculator here. I've never got around to trying it myself so I can't say how accurate it is personally, but I've heard good things.
