Need Power Supply suggestions!

[handsman]

Here is my setup:



Intel i5 3570k - $220
Radeon 78702gb - $240
Corsair Vengeance 8gb (2 x 4) - $40
2tb Seagate Hard drive - $90
Samsung 830 64gb - $110
Gigabyte z77 - $140
Intel Gigabit CT PCI-E Network Adapter -$30
Asus Dvd drive - $25
Cooler master 120mm fan - $8

Case:
ATX Cooler Master Elite 431 - $47

My ideas for power supplies:

Corsair CX600w - $90
Cooler master extreme power plus 600w - $70

I need to know if 600w is good enough and also if I will be able to get a second 7870 for crossfire.

Thanks in advance!

600watts is plenty and the Corsair is the better of the two. Theoretically 600watts is enough for CF setup but most 600watt do not have 4 PCIe power connectors needed for two of those cards, 700-750 watts do and leave more headroom.

Ok that makes sense, I can get a Cooler master extreme power plus 600w for $70...

Can you recommend any power supplies? I am thinking of going for an 80+ certified just to use less energy but I don't know where to start.

CM extreme power is crap. XFX 650watt http://www.newegg.com/Product/Product.aspx?Item=N82E16817207014

Im buying from Amazon, and I have prime so I get free shipping.

@rolli59

On amazon the 750w is $95 but it has a $25 rebate!

I am definitely going with this one!

Thanks!
