Default Choosing a Power Supply Unit

I am going to buy the Palit Nvidia GeForce GTX260 Sonic, so I am going to need another PSU.

1. I need to know the amps needed on the 12V rail.
2. Which PSU do you think is better: Antec NecEco 450W OR CoolerMaster GX550W OR CoolerMaster Extreme Power Plus 460W

Thanks...

Sorry I know this answer is not exactly what you are looking for but I recommend buying this unit. its a good brand and although it is slightly costly it is a good PSU.

Of the three, I would suggest the CoolerMaster GX550W. They recommend at least a 500W unit for the GTX 260.

Itll be fine. The card doesnt draw a lot of power.

Go with single rail if possible though. Its harder to overdraw.

Ok... I just found out the card needs 36A on the 12V rail. Now I am comparing the CoolerMaster GX550W [http://www.coolermaster.com/product....oduct_id=6641] and the Antec NeoEco 520W [http://www.newegg.com/Product/Produc...2E16817371030].
Can u tell me which PSU is more reliable?

The card does NOT use 36A.

It depends on your system. the antec is better of those 2.

They are both good units. I prefer Antec power supplies for their reliability, performance and excellent customer service.

This may help you: Single vs. Multiple +12V rails: The splitting of the +12V rail
