Wondering if my current power supply is enough to handle upgrade?

I currently have a Corsair CX650M 650W power supply. I am adding a Sapphire NITRO R9 Fury and two Western Digital 250GB SSDs. When I put it all together on PCPartPicker, the max wattage comes up to 554W. When I used the OuterVision Power Supply Calculator it added up to 544W. When I used the Cooler Master Calculator, it added up to 424W. Which one sound about right? Would it be safe to overclock or should I wait and upgrade my power supply later on? Thanks!

Absolutely fine with that spec list & a fury mate.

I don't think either calculator is right , you'll be maxing at 480-490w IMO.

To add - that figure would be under stress testing with both CPU & GPU running 100% load.
That's a very unlikely scenario & you'll be under 400w the majority of the time while gaming.
