Thanks for information.
I've already had a power issue when i added Indi.ECS Scandoubler on the top of ACA500 & ACA1233 combination.
I changed my old ATX PSU to a new one which can provide 20A current on +5V rail. Please see the table below link.
According to this
page an A1200 with 68060 card , 2xHDD & SCSI card consumes 3A on +5V rail.
so (roughly) my psu should still have 10-15A@+5V margin to provide required power for Rapidroad.
since i have no electrical&electronics expertise, i am not sure that is the correct approach/calculation for the situation.
What do you think?

The Delfina/Silversurfer side would be the correct side. However, I have to reapeat: I do not recommend to operate all this without a good power supply. Since ATX power supplies are no good due to their main rail being the 12V line (not the 5V line as required by the Amiga), you risk the life of all components on that setup.
My current plan is to include a DC-DC converter with the X-Surf-500, so you can add power for USB using an off-the-shelve 12V DC supply.
