New HD3870 cards for CF but is PSU enough?

[licken]

Okey, im about to buy some new stuffs, a new Core 2 Quad Q9450 and two HD3870 cards for cf, but do my PSU have the power to keep this stuff running?
Without the watercooling then, but with some OC ofc!

Psu is: Tagan easyconnect 580w

so happy for any help i can get in this!

I think that it's enough power...
You can calculate recommended PSU wattage here: http://www.extreme.outervision.com

I have a Thermathake pure power 520W E6600 (3.7Ghz ) 4Gb ram and 2 HD3870 and it can not take the load :(

that PSU calculator say's that i need 472W but my system can't run on a 520.
I think if you use that calculator you must add at least 100w.

I think its a bit small if you are going to oc your cards and cpu.

dont skimp on the psu... it will cause instabilities especially when overclocking.... youll end up with a system that does nothing but give you a head ache...

Also, make sure you buy a quality PSU from companies like Corsair, OCZ, Antec and Thermaltake as well. I highly recommend a Corsair HX 620.

that psu is bad thats why it doesnt give out enough power, a good tier 2 or 1 psu will abide by the wattage rating given on the calc

how about the corsair tx750...

Is all about the Amps on 12v. And dont forget they get old too :( as they get older they cant put out as much power.
