You can get quite cheap and reasonably accurate power meters now. Build your system and power it from an existing PSU and use the power meter to check its consumption. Then you can buy a suitable PSU.
This is the one I have (though I didn't buy it from Maplin I don't think):- http://www.maplin.co.uk/p/15a-plug-in-energy-saving-monitor-l61aq
Maplins are always expensive (and this one is £19.99 which is too much, IMO), so I hit ebay:

£11.98 inc postage.
I think I'll get one to see where my power hogs are.
