I have a geforce GTX 660, so 1 PCI-e connector.
It's powered by a PC Power & Cooling Silencer 750W supply.
According to specs, the PCI-e bus should offer 75W max, and the 6-pin another 75W, leaving me with 150W.
The other spec was 20A max per wire. 20A*3 wires*12V=720W (okay, I think I'm good here.)
Thing is, I have the card modded to it can use 200% power, and it often hits this mark. That means the card will draw 250W max, and apparently gets close, according to PrecisionX 4.2.0. That's well above the stated limit of even an 8-pin connector. Is that a potential problem?
Can I just go ahead and proceed on, or do most power supplies prevent this much power going through the PCI-e 6-pin connector?
