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.

Other Info
All fans PWM; speeds at idle: CPU circa 500 rpm; intake circa 600 rpm; exhaust circa 600 rpm; CPU temps 27 idle and 47 C load in a warm room (27 C/81 F) when running Intel Extreme Tuning Utility stress test.
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.
