1) Is this PSU good enough for this rig?

eVGA 7900 GT KO
WD 74 Gig Raptor
Corsair XMS 2x1 Gig DDR2
Orleans 3500+ to be OCed to 2.75 ghz
Zalman CNPS9500
ASUS M2N SLI Deluxe
Centurion 5 case with 120mm and 80 mm fans
1 DVD/CD RW combo drive
1 floppy

2) in a year would I be able to go SLI with another 7900? Or would I have to get something like the OCZ 600 W Powerstream? http://www.tigerdirect.com/applicati...&Sku=O261-2004

3) What I'd really like is a modular PSU that could run this rig with the potential to go SLI. Any cheap, yet quality ideas?

Thanks in advance
