GeForce GTX 570 Specifications, Release Date Leaked
- Thread starter RavenXXX2
- Start date
That was a very, very sad day for my wallet. I won't touch furmark or Kombuster, I really don't see the point, it's like buying a car and driving it flat out in first gear around the M25 to see if it's reliable.

Id say your well covered now, shame when they do go wrong though, after reading your posts i was a bit wary, even considered adding the 620w psu from my old rig to power the gpu's, case has room for a psu in the top or bottom, thankfully i didnt have to go to that extreme.

If that is the case then the chances are that it will only be in selected applications like the GTX 580 and that it will also be possible to disable it via a 3rd party program (GPUz).
6 pin and 8 pin PCIe connectors both only have three live +12v wires, so I think it's a reasonable assumption that even a 6 pin connector could supply 150W to a graphics card at least without any issues. The cables themselves will also have hugely over specified for the job they have (they could probably take at least 2-3 times the rated current for the connector), and over clocking will never provide the increase in power draw to damage the PCIe cables.
The only time I have ever heard of any issues with cables/connectors melting was when people were benching quadfire 4890s and either the ATX or EPS12V connectors were melting/burning out because the cards were drawing too much power from the PCI slots. However there was a mod that fixed this by adding an extra molex connector onto the relevant pins on the motherboard connector.
Either way, having insufficient power connectors will not limit your over clock in any way shape or form, so your over clock would never have been better if the card had an extra power connector from the factory, which is what was initially suggested.
I don't think it being single versus multi rail is a big deal (from what i've read), it's more the quality of the unit and how close to the edge you're pushing it.
The Revo's got consistently good reviews and seems to be a favourite with the boutique system builders so I'm happy it's fine. It didn't kill it pumping 1120mv through both 470s for the last 4 months so I take that as a good sign.
Fingers crossed of course!

In theory... I've seen enough stuff like what happened to arcane to be a lot more cautious - especially with multi-rail PSUs.

Arcanes issues was not due to the 12V rail being insufficient, in fact it was because it could provide the power that his ATX connector melted. The reason his ATX connector melted was because the socket and the plug are only pushed together, so the contact between the pins isn't perfect and therefore the resistance is quite high at that point (relative to the wires etc). So if a large amount of current was being drawn then a large amount of heat would have been generated at that point making the connector melt.
Having a PSU with a beefier 12V rail would not have saved his ATX connector from frying, what might have would be an additional power source for the PCIe slots on the motherboard (a molex connector).
