What power supply?

[Whirlwind]

Get yourself a nice beefy power supply for that system.

You wont regret it.
At least 550 watts and 36 amps on the 12 volt rail

Just get the truepower trio as it has plenty of Amps on the rails for a SLI system.

Here it is again.

See this is what I hate about SLI systems though, the amount of watts
it requires, and the Heat it produces always suck....

Just get the Antec as it's the best one for you without spending any more.

The power supply Sora listed above should serve you well.
