I wouldn't have thought It was far off!!

PSUs have to be the most overkill thing that PC builders put into their PCs.
I've seen guys on here look at order 1,000 Watt PSUs for systems that probably run about 300 Watts.

That website won't be entirely accurate but give it a margin of 100 Watts and I would be confident with it.

you'd be surprised at how little your computer actually uses.

Almost any machine (barring dual CPUs + Dual GPUs) can run on a decent efficient 650 Watt PSU nowa days.
