hello people, i recently bought a geforce 750ti OC edition since my power suplly could handle it, after buying it i noticed the VGA requires a 12v 20a line and my psu has four 12v 18a lines. Will it be a problem? i hav a molex to pcie adapter but has no cable on the 2nd pin, can i use it to form a 12v36a line?
GTX OC 750ti on OCZ600sxs PSU?

it will be fine. strange they would rate the card at 20a on the 12v line. that would be 240w which even a gtx970 wont draw. maybe they are accounting for the total system amps on the 12v line.
anyways, the pcie lane itself supplies up to 75w. each 6 pin pcie connector can supply up to 75w and an 8 pin can supply 150w.
some gtx750tis dont even have a 6 pin connector, they get all their power from the pcie lane itself. your model draws a bit more since it has a fancier fan on it and a slight overclock. so dont worry, you would be lucky to hit 100w total power draw with your card and thats about 8.5amps load on the 12v side.
