Thanks for reply
well the psu isnt that old, i bought it like in february and since then its working without problems so far with the same specs plus an hd4670 , in the specifications it says that have 32 A on the 12 V rail
then the 5770 would have to work using only one molex right? because iirc the pcie slot provides 75 w and each molex another 75 w, and i dont think that the card needs more than 150 w.
and as i say this is just temporary, like maximum 2 months
have a nice day
