Does a graphics card with a 6-pin connector perform differently than one without?

I was looking at two graphics cards, the EVGA GTX 750 ti SC 2gb, and the ASUS GTX 750 ti 2gb. The EVGA card comes without a 6-pin connector, while the ASUS card comes with a 6-pin connector. I was just wondering if there was a major performance difference in cards with a 6-pin verses cards without it that draw power from the mobo.

The 750ti only needs about 60w at stock reference speeds. A PCI-express 2.0 slot can provide 75w.

Now if those cards are overclocked, have a few more powerful fan's, etc, they will push to that 75w limit. This is fine, the slot should be able to handle it. This is also depends on your PSU to supply good power to the motherboard.

Using a 6pin, which can also supply 75w, Asus can essentially use no power from the PCI-e slot, thus, in a sense, allow more power to the motherboard, more useful for overclocking, better board stability, etc. 75w being drawn through your motherboards adds heat the MB, etc.

The slot is rated to provide the power it needs though, so either should be fine. I would say the quality of the PSU and MB...

Usually, cards need all the power they can get, so they need the 75w from the slot, plus 75w from 6pins, or 150w from 8pins. The 750ti is a unique card that is has some power to it, and can still be powered by the slot alone. I sort of like the Asus though for using the 6pin for it, providing they offload all the power to the 6pin and not draw from the slot.

SC stands for Super Clock and is factory overclocked. The ASUS video card is intended for overclocking, thus the supplemental power connect necessary to reach higher clock speeds. If you do not intend to overclock the video card, get the regular one.

Except according to what the OP said, the SC is the one WITHOUT a 6pin.

Short answer no there is not much differance if your going to keep them at stock settings.

The card with the 6 pin connector would likly be able to OC better, but thats always a crapshoot so...

Saw my mistake right after I posted it. Reverse it and it still makes sense.

i'm sure it will be fine .. it just seems the 750ti at stock drawing the 60w is close to the 75w from the pci-e slot and there oc cards with extra cooling fans or larger fan they felt it needed the extra 75w from the 6 pin connector so not to overload the max power from just the pci-e slot ??

that's the only reason I see from that . I don't guess I seen another card that does this .. any way you did point out something I took for granted now I know to look at that between like cards
