Approx. PSU requirements

[AKASchwanksta]

Hey,

I was wondering what y'all thought was an appropriate PSU for this system. I ask because I have two options. Either get a second AMD 5770 or a 6870. If I get another 5770 I'll have great performance but I'm afraid I might go over my rated PSU. My current PSU is a corsair 550W. Proposed system:

i5 2500k (will semi-aggressively overclock)
2 sticks of 4GB DDR3

BIOSTAR TP67XE LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard: http://www.newegg.com/Product/Produc...82E16813138289
7,200 RPM SATA drive
64 GB SSD
No optical drives

I think you should be ok with another HD5770

Should be fine in either case.
