Thanks again Khenglish and jaredhello, this was very helpful. I find it interesting that the high voltage rail is tied to external supply voltage. I would have guessed that it matched desktop rail standards, basically that the motherboard dropped it down to 12/5V before sending the line to the card. The bigger pipe is less power limiting, so that must be the thinking. Limits using higher voltage supplies with future laptops, but I suppose there isn't much reason to go above the voltage specs of the 330W Clevo bricks. I'm going to spend some more time of Digi-key now. I believe I already found the matching 2V 560uF caps. Originally Panasonic caps all around based on the pictures, but maybe I can top them from someone else. Thanks for an estimate on the small cap size, finding that one has been killing me. I'll look for 24V+ in that size and find the best capacitance/esr balance. Kheglish, you mentioned two Vcore caps, are the two down and right not the same as the array of six above?
