600w PSU for RTX 2080 Ti? in Graphics Cards Posted 2 hours ago 8 hours ago, Fasauceome said: Are you saying that the AX860 isn't 80+ platinum? I don't see what you're getting at here. 546 watts from the wall roughly translates to 500 watts of power delivery, based on a 92% efficiency. That's not a spec or anything, that's just some napkin math based on 80+ platinum. My i7 8086k at 5.1ghz uses 152 watts max. You have one so you could test it yourself. My EVGA uses 387 watts max. That is a bit over what it states in the bios but I posted the bios images here. The only bench/game that hit my CPU and GPU hard at the same time is AC:O and that is how I test real world max output. All my synthetic benches hit one or the other but none both at the same time. GPU Z tells me I am using 383 watts max when playing. The ASUS EC sensor on my Hero board tells me the CPU power usage through HWiNFO is 132 watts when playing. The power meter plug readings go well with what the software is telling me so I would like to know what is off. Is it GPU Z, HWiNFO or my power meter that is off. Do you think the software is catching spikes in power usage that the power meter does not see? Like on the other side of the PSU(not the wall side). All I want to do is figure out what is causing the discrepancy.
