Is this PSU going to be enough for my new rig?

I have been ordering components to build a new system, however I am not sure if my current system's PSU will be able to handle my new rig's setup. Perhaps someone can give me a hand in figuring out if I am going to have to buy a new PSU (which I hope not to do as I am trying to to keep this within budget.) Any and all help will is greatly appreciated!

Current PSU:
Silverstone Strider 600 Watt

+3.3V +5V +12V1 +12V2 +12V3 +12V4 -12V +5VSB
Max.(Amps): 25A 24A 13A 18A 16A 8A 0.5A 2.0A


New system I hope this PSU can run:
AMD Phenom II X6 1090T @3.2Ghz
Asus Crosshair 4 Formula
16GB G.Skill Ripjaw (PC3 12800)
eVGA GTX 570 Superclocked
3 HDDs (sata)
1 - DVD-RW
5 120mm case fans (including CPU fan)

I know that if I chose to go SLi one day with another 570 card I wouldn't be able to do it with this powersupply, but is it possible, for the time being, to have my current PSU run this system stable with no overclocking?

Thanks in advance for all replies!

to be honest dude for the price of a power supply you might as well over do it. Power supplies are pretty cheap on the list of your components. I remember i used to run an old 7950 Gx2 off a 300 watt power supply and yes it worked but I was always worried about it crapping out. So id spen the extra 20 bucks for the peace of mind. just one mans opinion though
 
Your PSU is rated for a total 42 amps at 12 volts, not the higher total you get from adding up the maximum from each rail. That will be your real limiting factor.

The two biggest power users will be your video card (around 18 amps) and the CPU (around 10 amps). Total, that's about 340 watts. Motherbard - about 50 watts at 5 volts. Memory - 30 or 40 watts at 3.3 volts. The four drives - no more than 70 watts. Fans - no more than 20 watts.

That's a high side estimate of 520 watts. That's closer than I would run, but your present PSU is adequate.
