How much wattage for SLI?

How much wattage would it take to run SLI GeForce GTX 550 Ti? I have a 630W SLI ready power supply, but is that enough? They take 400W it says.

It says here:

GeForce GTX 550 Ti review MSI Cyclone II OC

About 140 watts for each card, under extreme load.

Plus the rest of your system.

You likely have plenty of watts, unless you have a lousy PSU.

eVGA recommends at least 400W, with 24A on the +12V line, for a single 550ti. The second 550ti would draw less than 150W more (12.5A at 12V). Your PSU is rated at 22A on each of its two 12V rails (44A total).

You have margin enough.

I was going to link the psu I have, but I guess you looked it up. Thanks.
