Justa wondering

Well, it sort of depends on other system specs. Assuming 2x4GB RAM, i5-3570k, z77 mobo, dvd-r drive, 7200 HDD, you'll be ok, but will have rather limited leeway for OCing the CPU.

That card pulls 256W at full load. So a Seasonic 620 W PSU should be just fine for pairing them up if you don't have any other unusual loads on the system.

Righto, also other specs

Intel Core i5-3570K

G.SKILL Ripjaws Series 8GB (2 x 4GB)

BIOSTAR TZ77A LGA 1155 Intel Z77

SAMSUNG Spinpoint 1TB

and some LG dvd burner

That would be horrific.
The entire water cooled, overclocked I7-965 / X58 system it was tested in drew 256 watts
