AdamB170Renegade5399AdamB1701 very good reason for a kingpin or lightning z is the 3 power connectors. "2080 ti's can pull 400w from the wall with just a mild oc. I've seen mine spike up to that anyhoo. Don't know how accurate gpu-z is but 2 power inputs are just stupid on these cards. 2 x 150w + 75w pcie leaves zero headroom. All 2080 ti's should have 3 power connectors.Please see here: //xdevs.com/guide/evga_2080tixc/ Since it's a lot of scrolling, here's the part I'm referring to: This RTX 2080 Ti have both 8-pins located on top edge of the PCBA. These can provide plenty of power for any normal-condition benchmarking, stress-testing and overclocking.There is common misunderstanding to refer 6-pin or 8-pin MiniFit.JR connectors as fixed 75W or 150W power capable inputs.Nothing can be further from truth actually, as connector port itself does not define the power cap. These power levels are nothing but just the way for how NV determine capability of used board hardware to deliver high power to the voltage regulators. It’s purely imaginary specification and have nothing to do with actual power taken from connector nor power input capability. Active circuitry on PCBA after the connector is used to measure current flowing from the connector into the VRM. This enables software, driver and NV BIOS to handle GPU clocks and reduce voltages if measured power hitting programmed BIOS limit value (which can be lower or higher value than 75/150W!).So if we play and change circuit to adjust the calibration point, this limitation will be lifted accordingly as well. Also to make sure we are not at any physical limit of power connector itself, check Molex 26-01-3116 specifications, which have specifications both 13A per contact (16AWG wire in small connector) to 8.5A/contact (18AWG wire). This means that using common 18AWG cable, 6-pin connector specified for 17A of current (3 contacts for +12V power, 2 contacts for GND return, one contact for detect). 8-pin have 25.5A current specification (3 contacts for +12V power, 3 contacts for GND return and 2 contacts for detection). This is 204W at +12.0V level or 306W for 8-pin accordingly.Now when somebody tells you that 6-pin can’t provide more than 75W, you know they don’t understand the topic very well. It’s not the connector itself or cable limit the power, but active regulation of GPU/BIOS/Driver according to detection of used cables and preprogrammed limits. So how actual power measured? Will see later on detail shots of the RTX 2080 Ti PCBA.Yeah, I'm going to try to delete that. Literally 5 minutes after I put it up I watched buildzoid review a lightning 1080ti and he said each cable can manage way over 150w. Cheers.

xblackvalorxI that was after playing with it. I lowered from 2210. I don't see how lowering it would have made a difference, as the card was able to sustain 2130-2145 without going lower. I'm just saying for all the hype they put on the lightning z I thought it was going to be more in league with the kingpin, but it seems closer to the ftw3And there are plenty of evga cards ahead of you. Seems like you're kinda just side tracking this thread to brag and don't even really have much to brag about.
repo1979really hope they come out with a hydrocopper version
