Parts:
- AMD Phenom II X4 955 Black Edition
- GigaByte GV-N460OC-768I
- ASUS M4A87TD EVO
- Team Elite DDR3 - 4 GB ( 2 x 2 GB) 1333 MHz / PC3-10660 - CL9 - 1.5 V
- 2 HDD 7200 rpm SATA
- 1 DVD drive
- 4 120 mm fans

According to this website, i need 700W of power, but to me that does not sound really realistic.

I was planning on getting an OCZ ModXStream Pro 600w OR and Anted EarthWatts 650W OR Antec EarthWatts EA500D Green (500w)

Will 500-600w be enough for this build, also which one of the 3 would you recommend?

GO EAGLES!

The general rule of thumb is a high quality 500 to 550 watt power supply with sufficient current (amps) on the +12 volt rail(s) can easily power a system with any single video card made. A high quality 700 to 750 watt power supply with sufficient current (amps) on the +12 volt rail(s) can power a system with two video cards operating in dual mode. There are a few exceptions like the new ATI Radeon HD 5XXX series cards which use less power due to their energy efficiency and the new Nvidia GTX480 which uses a lot more power.

The 460 you mentioned uses less power than the 480. You should be fine with a high quality 500 to 550 watt power supply.

A high quality 500 to 550 watt psu will have a +12 volt rail rated at 40 amps. A high quality 700 to 750 watt psu will have a +12 volt rail rated at 60 amps.

In addition the power supply should be at least 80+ Bronze certified for energy efficiency. There are some models available which have achieved 80+ Silver and 80+ Gold Certifications.

Before purchasing a new psu you will need to decide whether you will eventually have a pc with one or two video cards.

Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units. One example would be the newer Antec power supplies.

any of three you mentioned would be enough. i run a similar system on a corsair 600w PSU (OC x4 955, GTX 460, 4GB RAM).

of the three PSU you mentioned, I would go with one of the earthwatt units like the 500w unless you want to run SLI then go with the 650w.
