post #1 of 23
Thread Starter 
well i wanted a small upgrade so i went with an x1800gto refurb from the egg and didnt even consider that i might not receive the molex to pci-e adapter and my psu doesnt have one. can i cheat and "make" one or do i need to buy one for like $8 to use my new card?

Yellow = 12V
Black = Ground

That's why in the picture the test is colored. The color of the text represents the color of the wires

well that could have gone better. some red light on the black power connector and nothing. so i scrap that idea and cant get past windows loading screen with my vid card, im on onboard gfx now. something may have been wrong before i tried it though as windows explorer was not visible after i uninstalled the ati drivers and adjusting the screen etc would not make it visible.

That light is supposed to come on and then go off... it's a diagnostic light. If it stays on then something is wrong. I would suggest that you plug in the last pin to 12V because I looked at my connector and it has 3 12V and 3 ground. Maybe that's why it didn't work.

how can i have three 12v? isnt there only one in each molex? the link you sent me to by W1zzard has two 12v on bottom and three ground on top.

NEW PROBLEM:
anyway i cant get past the bootup screen with my old vid card, i have to switch to onboard which is really confusing.

basically when i boot up with my vid card (old one) it hits the windows screen with the bar and doesnt go to log in. using onboard gfx i can use like normal. any ideas why this is?

Um, why do you think the converter needs two molex's?
