Is this power supply asking for trouble?

I'm looking to add a cheap GPU to a second system - just for some very light gaming at 1080P. Had roughly settled on an Asus GTX 960 Strix - mainly because it only uses one 6-pin for power, and seemed about as good as I could get at a low TDP, and below £200.

What worries me is, my power supply. I'm using a Seasonic G series 360w '80 Plus Gold' unit: https://www.overclockers.co.uk/seasonic-g-series-360w-80-plus-gold-power-supply-ca-020-ss.html

Obviously, it's not like it's a cheap piece of garbage...but I'm worried that 360w might be cutting it pretty fine, even with a GTX 960 (I really didn't buy the power supply with any intention of using it with anything other than integrated graphics at the time).

System spec - which is a bit of a hodge podge of parts - is as follows:

3770K (currently at stock)
K2 Mount Doom cooler (stock fans)
ROG Maximus V Formula
8GB (2X4GB) Samsung Green DDR3 (also at stock)
128GB Samsung 830 SSD
500GB Seagate 5400RPM mechanical
No optical drive

Really just wanted some feedback to either reassure me - or tell me I'm probably playing with fire :o I've tried various power supply calculators...and some seem to say I'm just about ok (as long as I don't overclock); others seem to imply I'd need more like 380-400w. So, any help or suggestions would really be much appreciated!
 
Thanks so much! That definitely helps put my mind at rest. I guess I'm usually the kind of person that just slams a 1000w Seasonic or Superflower in my main rigs, without thinking - just to give me lots of flexibility/headroom. New territory worrying about this stuff! But relieved I won't have to swap out the power supply :D
 
To be honest, had I known I'd be installing any kind of graphics card, I'd definitely have spent the extra and got a decent 650w, myself. With a bit more wattage, I'd have been fine to grab a used 4GB GTX 770 or 7970GE/280X - which are both probably superior - for less.

Oh well...moral of the story - there is no such thing as overkill ;)
