is my PSU strong enough?

I have a 290X on a 600W PSU and I sometimes overclock it (I can click on a pre-set oc if I feel the need for a bit more performance). I also have a meter to check power consumption, the highest power input into my PSU that I've seen was just under 500W, my CPU is an i5 4590.
