It currently pulls in what, 296W TDP? and can't go over 300W without pushing it out of the atx spec.

2 8-pin power connectors would allow it to pull up to 375W within the ATX and PCI-E 1.x specs.

Would it? Two 8 pin - pushing 150W ea. - would put it at the 300W cap



edit: my bad - been a long day + 75W for pci-e throughput

Now I'm back on track here

my stupidity
The PCI-E 2.0 spec allows for 150W through the slot as well if I remember correctly, so if they decided to ditch PCI-E 1.x compatibility they could make a 450W card as well.

True, but then your placing the requirement that people must have both a dual 8 pin compatible video card and PCI-E2.0

Not saying it is unreasonable, but I suspect then want to keep their options as wide open as possible?


But ya I guess up to 450W would be possible. Damn that would be a mamoth of a card, and heaven forbid you ever wanted to get two

There IS no ATX specified limit. ATX specs just limit the amount of power that can be pulled from the connectors / slot. There was no 6-pin connector until the spec was changed to incorporate it. There was to 8-pin until the spec was changed to allow it. Having 2 8-pin connectors on a PCI-E add in card won't cause anything to go outside the ATX spec as long as all the certifications are received.

How else do you think the ASUS MARS received the go-ahead?

I think it's the PCI-E 2.0 spec that officially limits devices to 300W/slot. Technically, the slot (150W), plus a 6-pin (75W) and an 8-pin (100W) allow for 325W under ATX specs, and a pair of 8-pin's would boost that to 350W. For that matter, there's no reason they couldn't just say to hell with it and add a third plug. And with a little pressure, I don't doubt that they'll come out with a revised spec - maybe PCI-E 2.1 or something like that, with higher TDP's allowed.

Obviously all this would limit their market, but these are halo products to begin with, and I don't doubt some motherboard makers would love to charge a premium for "PCI-E 2.1" certified boards.

There is no power limit in the PCI-E spec. Only a limit for how much power can be supplied by the slot itself (75W for PCI-E 1.x, 150W for PCI-E 2.x). And the 8-pin PCI-E connector can supply 150W of power, not 100W.

My bad, I stand corrected on the 8-pin power draw. But I'm fairly certain that the PCI-E specs do dictate how much power can be drawn by the device, according to what connectors are attached to the device. It doesn't encompass the area of chassis/board/supply testing, so the onus is on those designers to make sure their products can supply what they're supposed to.

I believe the 300W number comes from assuming 75W from the slot, plus the additional power provided by the 6 and 8-pin connectors.
