You just can't pull that kind of power through 2 PSU plugs and the PCIe lane.
The PCIe cables aren't going to melt. An 8-pin PCIe on a high end PSU could be reasonably expected to safely deliver 250W. Of course if the PSU manufacturer used thin cable or cheap pins then you could have issues, but people on OCN don't use that type of PSU. Or if they do I make sure they change it.

Are you suggesting that GTX 590 has 575w at its disposal?

It would be awesome if Nvidia and AMD merged. We could have overheating, broken drivers and ridiculous prices. A boy can dream.

Assuming the PSU can handle it, yeah. Though the VRMs are still the bottleneck.

Was the reason for HD 6990 huge price of $700 all because the board was designed to handle 450W no problem?

I should think it would have all the power it asks for 'at it's disposal', up until the point where the PSU's OCP circuit(s) kick in and shut down the PSU.

There may be some multi-rail PSU's out there that wouldn't allow you to draw a whole lot more than 150W through each 8-pin (i.e. the few that actually deploy spec-stringent OCP circuits), but if you had like a single +12V rail 850W unit, it would very happily provide 575W to your 590 (provided your total system load didn't trip the OCP for the entire unit).

In this particular case, the question then becomes: "are the wires on the PCI-Ex cables of a low enough gauge that this kind of current draw doesn't cause them to get too hot and melt their sheathing?"

Looking at the gauge of the PCI-Ex power cables on my 850W single-rail unit, I'd guess that they could easily transmit 250W per cable w/o an issue. On a very cheap/improperly spec'ed unit though, like Phaedrus mentioned, if they used higher-gauge wires ... there could conceivably be a problem with this sort of draw.

I hope future NVIDIA cards aren't like the current ones (570/590).
Well, they're trying to compete with AMD. Prices have to be cut somewhere

No amount of well-placed words will convince a body of people to do anything that is entirely against their motives and goals.

You were misguided. But it's alright! All we ask is that you have more a realistic, down-to-earth vision of things in the future. There's no sense in doing the same thing over again, even though it doesn't work. I mean, it's like a child who wants a new toy and decides to write his parents "grown-up" words to try and convince them. It's cute, but childish.

All you need to do is understand that you can't CHANGE things. You can only feel better about them. We'll listen to your angst, which we all share, and in the end.. we'll get over this, just like we've gotten over everything else.

Just promise not to do something like this again, ok?

Love,

THIS IS TOO FUNNY RIGHT HERE!!!!!!!

Look who,s talking =

"your egotistical attempt at seriously addressing another human being with a superior tone borders on comical sarcasm., No amount of well-placed words will convince someone your point"
