PSU suitable for ASUS Nvidia geforce gtx 660?

[slabs007]

Hello,
I'm looking to buy a new gpu for my system! I currently have a superchanel s550 PSU and was just wondering if it has enough power for the Asus Nvidia geforce gtx 660!

System specs: Intel DZ77SL-50k motherboard
Intel i5 3570k 3.4GHZ processor
Corsair 4*2gig 1333mhz ddr3 ram

Currently using asus gts 450 gpu!
Any help or suggestions would be appreciated!
Thanx!

It does since the card only calls for 430watts http://www.realhardtechx.com/index_archivos/Page362.htm

yep it will work fine since the 660 consumes only about 20 watts more than your current GTS 450
