I upgraded my gpu from a 1070 to a 1080ti so
I bought this month the hdplex 400w v1.6 comming from a hdplex 300w
So, 1080ti and a i7 8700k powered by a 330W DA330PM111 dell brick and the hdplex400 in an s4m-c.
I powerlimited the gpu at 95% right from the start.
I must say, running all kinds of stuff on this machine to bring the system to a shutdown, it just doesn't happen.
The 330w dell brick i bought from amazon is getting just slightly warm and the powermeter at the wall shows me 385w peak, once it showed 473w (!) peak running assassins creed origins.
On this game gpu is at 100% and cpu is at 40-60%
So i must say, not knowing how that brick is able to handle that output, it works.
Although, assasins creed is the first game where coilwhine is noticable as fps go sometimes up to 400fps in menus. Turning on vsync or limiting the fps to 60-90 fps gets rid of that also
I couldnd make out where the coilwhine is comming from. Could be the gpu, could be the hdplex.
Hearing that some people get reboots maybe im just lucky i got a good dell brick?
Who knows
