6 + 2 connector can't be that special if you can use a molex adapter to power it :eek:

It is special in its own way. It is made of higher gauge wire and on its on phase/block/rail It is meant to be used on PCIex cards only. If you use a molex adapter, you are sharing it with other molex plugs such as HDD/DVD/fans. This applies on most PSUs

99% of PSU's use the same gauge wire's from what i have seen :eek:

I was saying that because most (from what i have seen) of the molex > 6 + 2 run a dual molex (3 wire ea) into a single 6 + 2 so ya :confused:

Most 12V single rail have all the yellows soldered in together. All of the same gauge. So really a 6 pin is capable, its just how thick the wiring is and how many amps it can carry.


I just took apart another PC power & cooling 750 to use as a 12V power supply, and it is all the same inside it. Reviews tested it up to a total of 60 Amps on the 12V rail.

Yea those are very strong PSUs and the main reason is the single rail. Most of these multiple rails are the ones I was talking about.

I have had great luck out of single rail PSU's

Hmm... OK.

All I will say is the 6-pin and 6+2-pin cables for my PSU both use 18AWG conductors.

That's why they are called single rail unit's, multi rail unit's split the load across several rail's but the source is still the same IIRC

Dunno if i make any sense, looooong weekend :roll:

I would never buy a multi rail PSU

I say some not all

Now that the cog's are turning i think i recall something in my OCZ literature (or a review i read) mentioning increased wire size for certain connector's on my new PSU zx850w, i actually think they are the 6 + 2 pin's for the GFX card's and the main ATX!! :laugh:

So. Cal.
GTX 670 Ti[/URL], is reported to use a 5 NVVDD phase power supply (VRM) design that draws power from 6-pin and 8-pin power connectors. The card will hence have 300W of power at its disposal.
In all probably what’s exactly demanded for such Uber/FTW versions to get above the 7950. That PCB and power section doesn't come cheap normally, so definitely a $400+ price tag. If true it kind of tells us the Kepler is still not any more power efficient than Fermi.

Here the problem those type of expensive to manufacture boards aren’t normally a long standing production offerings that don’t ever see the price breaks. So it means to me they’ll make a presence short term then disappear as soon a prices start to adjust. Nvidia and their AIB’s will get pressed in price and then they’ll be gone from the market in a few months.

Sure there will be the more "generic" GTX 670 Ti's that might have both 6/8pins, but that will be for the more DIY OC’r, but those more generic OC versions (more or less competing with 7950) will hold to a 225W TDP and not offer as robust power sections.
