They make noise, too.

ces - please go back and read the original post. Particluarly the part that read:
...fastest no 6-pin PCI Express supplemental connector videocard currently available


It doesn't matter WHY it needs to meet this specification, just that it DOES meet this specification. Maybe the user doesn't have a 6 pin PCIe connector. Maybe he also doesn't have any spare molex connectors. Maybe he's running a modular power supply and lost all the extra cables.

Why is that important. It could mean that the card is just putting additional stress on the motherboard. Shouldn't the only thing that counts be how many watts it uses, now how it is wired to get those watts?

Personally because it sucks additional power that actually I don't have: maximum 75W is what I may supply to a videocard.

The standard/reference/typical HD5750 sucks from the PSU from ~30w to ~40w more than the PowerColor Go! Green (see TechPowerUp, neoseeker and other sites), not to mention that without the connector it won't boot.

What PSU and other components are you using?

In terms of price, you should get the 5670 instead of a 9800GT. Lower power usage, and almost the same performance.

If you want the 5750 Go! you have to wait. It showed up two months ago, but it's going to take a while to get it.
It's the only 5750 that stands out from the rest, and I guess it's popular.

If the 6 pin power connector is present the card can use up to 150W and still be in spec for PCIe.

If they design the card with no 6 pin connector that is a pretty solid guarantee that the card won't exceed 75W down the road after a driver update or a new game comes out.

But the 5750 go green is in stock at Newegg and has been throughout the entire discussion in this thread.

Zipzoomfly has had it in stock occasionally and sells it cheaper than newegg (which explains why it keeps selling out).

I don't think it's fair to say this card is impossible to find. Depending on where you are it may be harder to find.

I do think it's fair to say that it is an expensive card for a fanless card but then the title of the thread is "fastest". Of course if it were "best bang for the buck" under 75W I still might say the 5750.

Hmm, I see I made an error in another thread comparing these. Prior I said 62W when I meant 52W in the comparison below.

a typical 5750 card will idle about 13W and peak about 71W
powercolor go green 5750 idle 14W and peak about 52W

The non Green version draws 15W more in 3Dmark03 nature and 30W more in furmark. Note that is the powercolor to powercolor comparison.

But it is more of a difference than I had in my head going by memory. Thanks for the wakeup call.

I also just noticed the power numbers were taken at 1280x1024 which is a lower resolution than I would use on a 5750. So the worst case scenario in a game at higher resolutions may draw more power.

Is this true?

On a Gigabyte 7800GT that I have if you don't plug up the PCIe 6 pin connector the Nvidia driver gives a warning shortly after the desktop shows mentioning that performance will be limited due to lack of power.

I'm assuming ATI does something similar but I haven't tried it yet as I haven't bought any ATI cards that use the 6 pin power connector.

Dumb question: Does the 5750 or 5650 have any non-obvious functionalityor design attributes that would make it less useful on an office computer than the embedded video controller in the i3 series.

Yes, it's true. I have tried it with mine. The Powercolor 5750 Non-go green version will not boot if the power cable is not connected.
