![]() Like I said, though, I don't believe this would happen with the 3070 as it's using the smaller GA104 die. ![]() buying a highly-rated 1000W unit that probably won't have any issues). This is why some people have been over-buying their power supplies (i.e. So, though you should theoretically be able to get away with 750W-850W for an RTX 3080 ti/10900K build, some power supplies in this range might not actually be suitable, though it's hard to know which ones without professional testing. When this happens, especially if you are using a high-wattage CPU like the 10900K as well, power supplies with over-zealous overcurrent protection settings may shut the system down, even if the power supply "should" be able to offer sufficient power for the system based on the typical power draw of the CPU and GPU. In the past this was an issue with certain GTX 970 models, as well as Vega 64, but this time around it's an issue with any of the GPUs that use the GA102 die (that is to say, RTX 3080, 3080 ti, and 3090) and also to an extent with the 6900XT.īasically what happens is that the cards can sometimes pull way more than the rated board power for just a few milliseconds, sometimes spiking to well over 500W of power for the GPU alone. So, there is a problem with certain video cards that have super-high transient power spikes of only a few milliseconds or less.
