Repost: Graphics card with two power connectors?

[dwangus]

Hi, my computer model is an emachine ET1331-02.
As I've already had enough trouble breaking open the back of the case's metal slots (problem described here: http://www.tomshardware.com/forum/284059-33-cant-insert-video-card-emachine), now another problem arises.
I'm only 14, and I don't know too much about computers themselves. I recently got this new graphics card to enhance my computer, a Sapphire Radeon HD 4850, and its power connector has two individual slots, and in my machine, I can only see one visible slot to plug it in. Do I need both to power the card? If not, which one do I use (one has 3 wires connected and the other has 5)? And if I do need both.... I only have one slot. Please help me figure this predicament out.

On a side note, in the package with the Radeon HD 4850 came a copper wired thingamabob that says cross fire on it. I have no idea what it's supposed to do.

What? a HD4850 with 2x 6pin power connector?
Could you show us the picture of your card?

Sounds like your PSU doesn't have the necessary cables. The crossfire bridge is for linking 2 or more of your graphics cards together to work synergistically.

Yeah, strange, HD4850 with 2x6 pins? Never heard of it.

 

[unknown_13]

there where a few ATI 4850 released with 2x6 pin connectors (sapphire had one)

for obvious reasons they failed to sell

Are those the DDR5 versions?

 

[unknown_13]

maybe i can't recall. it like the ATI 4860, they came and went just as fast

Yes the HD4860 was the DDR5 version with 640 shaders (128) instead of 800 (160) shaders.
