You would be loading it up pretty good, but it should hold on if everything is run at stock and the PSU isn't ancient.

Hmmm ok i might be able to get away with it then? its just for a short period of time to do some benchmarking with but wasnt to sure if the 650 would be enough.

Your HX-650 should be fine for the time being.
But in the long run I would upgrading to a quality PSU that is 750-850W.
The Seasonic X-850 is on sale for $40 less right now if it interests you:
SeaSonic X Series X-850 (SS-850KM Active PFC F3) 8...

I live in Australia, and i was looking at the Corsair CX-750 V3 Power Supply? which should be good and at a not bad price

PSU calc puts you around 500W with load. In all reality unless you clock the cards and CPU up it should work for a long period of time. That being said I have skirted that line before. 500W unit to power a 3870X2 and Phenom II X4 with an overclock. Consumption was close to 80% on a day to day basis for 4hrs or so (built a rig for a younger brother) exhaust temps were ridiculous on the PSU, but it lasted about a year. Ended up RMA'ing it and the sent back a 750w which is still chugging along today in a different rig. It all just depends if you have a killawatt meter keep track of consumption and guesstimate using 80% for safety. I wouldn't run over 550W from that unit continuously and try to keep the peaks under 700w (after adjustment).
