Which one between these two?

Or would a Liberty 500W be enough power?

A Liberty 500W should be enough, but I would question its ability to handle an SLI setup w/ that hardware.

Buy an SLI approved PSU. Go to the nVidia web and see what they recommend.

I DO know that the liberty is SLi approved

Not sure about the TP.

I say Liberty ATW!

Go to nVidias SLI zone.....you gottum backwards. The antec IS approved, the enermax(Liberty) ISN'T

I heard Antec power supplies have problems with the asus a8n line, I have a a8n32 and I Got a seasonic right now but I ordered the liberty, should be in the machine by sunday, I'll let you know

The NeoHE and problems with the A8n. Only certain ones though.

There is a very large price difference between the Liberty 620W and the TPII-550. I'd get the Liberty 500W either way.

The Enermax has a pair of 12V rails rated at 22A each with a combined 12V rating of 30A.

The Antec has a pair of 12V rails rated at 19A each with no rating for the combined 12V rails. They do give a rating for the 3.3V, 5V and 12V combined, but unless you know how much your maximum is for the 3.3V and 5V combined, you don't know what's left over for the 12V rails.

Antec claims the rails are completely independent, therefore there is no combined max for any pair of rails. But if that were true, the combined maximum for the 3.3V, 5V and 12V rails would be equivalent to the max output of all four rails combined. It is not.

Because I've had a few Antecs blow up on me in the past and that piece of marketing fluff pisses me off... I'm going to vote for the Enermax.

Now if I don't go SLI, Enermax 500W should plenty? Right?
