Also known as the 1645 definitely consumes more than 90W. I don't care what Zlog says about TDP and electrical wattage. He's absolutely right that you don't know exactly how much wattage the chip is using, but TDP is rating of waste heat watts at max load. Since one watt of heat has to come from a watt of electricity, you are guaranteed at least 45 watts of electricity draw at load from the CPU. Add that to the (probable) increase power draw of the RGB screen, plus the fact that we're using a 4670 over the 4570 that combined with a C2D to draw 90.2...we're definitely drawing over 90.
I have no substantiation for even thinking this, but I've been afraid that the charging circuit won't be able to use as much current as we need it to! I'm really looking forward to the 130W test.
