Not that I know of. I used google and found a power consumption webpage for HDDs and one for CPUs (wikipedia actually), so you could do one for your motherboard and for each of your components.
With that in mind, you have a 550 W power supply, and based on your Video & CPU you have listed, if you have typical hardware (1 HDD, sound card is built-in to the motherboard, etc), 550 W should be plenty.
On the other hand, if you have a high-end soundcard, video capture card, and like a dozen USB devices, and other things I can't think of right now, you could (in theory) exceed that 550 W.
I run a 650W power supply with a Quad Core processor, 2GB RAM, 1 SATA HDD, USB keyboard & mouse, GeForce 8800 GTS and everything else is built-into the motherboard and have no problems.
My DVD-RW & Printer are USB devices that plug into the wall.
You can try this to calculate power usage for all your devices.
Can you tell me which PSU are you having, because its not just the power ratings, but also the reliability you must look after for if you wish to keep your components healthy.
