hello all

I have been looking for a power that will power with these specs:

intel 866 cpu
gigabyte 6bxc
384 mb of ram
dvd drive
gotek floppy emulator
NVidia GeForce 4200 ti
voodoo 2 in sli
creative labs awe 64 gold
usb 2 card
20gb hdd

i well aware that the 5v rail may be a issue and i have been look at the corsair power supply but the one i saw are 20a and I'm concerned it will not be enough. will the corsair ones be enough for this setup?
