Hi Fluzzyy
850watts will be fine or up to 1000w if overclocking
select a quality psu with high grade japanese capacitors from
seasonic/xfx or any pau from corsairs TX,HX or AX range of psu's

A high quality 600w can do it, 750w is a good amount for a PSU of "decent" quality.

Thats a good PSU. Superflower make some of the best PSUs. It delivers 648w (54a) on the 12v rail. I would use that with SLI 770s without a doubt.

Each 770 will only draw about 200w (17amp) on the 12v rail, still leaving plenty for the rest of the system.

well that's nice to hear! :)  i just tought it wouldnt be very high quality, since it was SO cheap :o  May i list the rest of my specs, if you may tell me will the PSU power the rest of my system with the SLI 770's? :)  I woke up to a tought that i could buy another 770 and stick it into my system, since i have some extra buck to spend :p

Yeah go for it.

If possible post up a picture of the spec label on the side of the PSU just to confirm, as I got the figures from the internet.

Yeah, i would like to overclock the hell out of it, but i think i bought too small & cheap case (Aerocool VS-92) so im afraid that i cant fit a proper cooler in there :(
