Wrong PCI-E Power adapter on MSI 7800GTX?

Hi,

I bought a 7800GTX 256meg second hand. My 460W PSU doesn't have the PCI-e power plug, so I used the adapter that was in the box. The card seem to run fine so far.

However I notice that only 3 wires goes from the 6-pin header to a male molex, and then 4 wire to a female molex. So only one molex provide the power.

The usual 6-pin adapters I saw so far in pictures on the net have 6 wires from the 6-pin connector, spliting to 2 female molex connector (which I guess provide 2 X molex power to the card).

Do you think I have a wrong PCI-e adapter? Anyone have a 7800gtx and can tell me if their adapter does indeed plug into 2 molex instead of one like for me?

If the card seems to be running fine then you shouldn't have to worry. If its the adapter that came with the card you SHOULD be fine. Usually a power starved graphics card will reward you with heavily degraded performance. What brand is the card and what are the rest of your system specs? Also, run some 3D benchmarks (like 3DMark05/06) so someone can verify your GPU's performance is where it should be.

I did run the 3D Mark 06.

Result seem a bit low on the online comparing web page, but I think they aren't problematic.

3DMark Score 4356 3DMarks
SM 2.0 Score 1746 Marks
SM 3.0 Score 1727 Marks
CPU Score 1776 Marks

I did a comparaison from this review:

It seem right to me. I will investigate more about what each pin should do.
