Or should I get one more like this http://www.newegg.com/Product/Produc...82E16817139006 ? I know the HX ones are more reliable and work better. Like for the graphics card it says minimum 630W without SLI but is that true? Thanks.

You have more than enough. GPUs always say they need more power than they really do. Plus Corsair is a high quality PSU so it will definitely be able to handle it.

I'd go for the 750. More wattage, more amps on the 12V rail, and more pci express connectors.

What are 12v Rails? How do you know it has more amps? But the 620 hx has more 12 volt rails? What are they? Are they needed? Isn't the hx 620 more reliable? Yhanks.

12V rails are what powers most of your hardware these days.

The number of said rails is not as important as the amps they produce, which are clearly stated on the sticker that all PSUs have.

If they produce enough amps to power your hardware, that's really all that counts.

I don't know if it's more reliable or not, I've never owned one...

12V rails is the type of power generally used most by video cards. While the 620 has more rails, three, they have 18amps each. The 750 has a single rail but is rated at 60 amps. You can look under specifications and then under out put. All those confusing looking numbers tell you how many amps are supported on each rail. The only reason I see to buy the 620 is that it is a modular power supply. That means you can plug in the cables that you need and not use the ones that you don't. This makes cable managment in your case much easier.
