Just got a new PSU, want to know if it's enough for SLi

[MTLink]

Hey guys. I just got a new PSU, a Coolermaster Real Power 450W. Right now I'm on AGP, but eventually when I build a new rig with PCI-E, I will want to SLi. If possible I would like to "recycle" as many parts as possible, PSU included. Would my PSU, which has dual 12V ramps with 18A on EACH, be enough for SLi?

Well ..... the official line from Nvidia (assuming you are using Nvidia) is

For your SLI system, you should have a power supply that can supply 30A from the 12V lines.

NVIDIA has a certification program that qualifies power supplies (SLI-Ready) that ensure 500W total output, 30A on the 12V rails, and 2 PCI Express connectors for your dual graphics cards.

The certified Coolermastern PSU is the 'Real Power 550 SLI' one

Personally I reckon it should be ok ....

The minimum power for sli is 500watts. So even if the 450watts would be able to hack it, its not gonna be stable. So RMA it while you still can.
