Thread Starter 
Hi, just wondering what PSU to buy for this:

i7 920 D0 under water @ 4.6ghz
6gb DDR3 1600mhz
And some harddrives.. and 3 DVD ROMs
I currently have a 750w, will that be enough?

1000w.

An 850w would handle it(barely), but most 850w units don't even have enough PCI-E connections.

I'll let others suggests a unit though, I haven't kept up with what has been released and what has been discontinued for a few months. All I know is that the ABS 1050w is out and it's usually the best choice at 1000w.

Off topic: anyone know how the new Silverstone Strider Gold units are?

Even if it only has 4 PCI-e's? Wouldn't three 6970's require 6?

An 850w will be more than enough. Just make sure you get a quality power supply. 1000w wouldn't be a bad idea for future upgrades, though.

Didn't know it only had 4...that's too little for a 1000w unit. Not sure what Antec was thinking on that one.

Each one of your cards should come with two Molex 4-Pin to 6-Pin PCI-E. That's the least of you're worries...

You shouldn't have to use molex adapters. That's just sloppy.
