An afterthought, is my PSU enough?

I have the below rig in the sig. Just bought an MSI nVidia GTX 560 TI although it hasn't arrived yet. I have a Corsair HX 520W PSU that I bought some years ago on recommendation and has done me good so far.

I tried to use a online PSU calculator but I cannot insert my specific details in to suit my current build. Is there an easy way to work out how much wattage the system draws so I can determine if my PSU will cope adding a high spec graphics card like this?
I have my system running of an IP PDU which shows current draw. Only this machine is on the IP PDU and current draw when running BOINC (max load) flicks between 0 and 1 Amps and back to 0. Going by this I can say the draw is roughly 1A under full load.

I think ultimately the question here is how do I calculate this? I looked up some google results and it seems very complicated to simply give a yes or no answer. Has anyone seen this site?

Thanks in advance
 
560 isn't a high spec card. Total load power draw for that rig is going to be in the 300-350 watt range. That 520 will handle it with ease.
 
Thank you.
I'm currently running a geforce 6200. So a GTX560 is way higher spec :)
 
I'm about to swap my mum's PC PSU over and see. I hope it hasnt. It is 3 years and 7 months old so nearing EOL any way. Just found a cheap 850AX on Ebay.
 
It's booted up fine with another PSU but I had to swap my old GPU back in as I was getting a single beep and no display. The spare PSU is a "came with" from an old machine and is only something like 300w so it will be okay as long as I don't crunch.

Going to watch Stargate SG1 for the rest of the day, then.
