I have an EVGA 850w psu, with two 2.5" hdds (5200rpm I think), two 3.5" 7200 rpm hdds, an msi 970 gaming mobo, amd fx8350 cpu, gtx 1060 graphics card, and an antec kuhler 920 liquid cpu cooler all in a corsair 750D case.
The antec 920 has two 120mm corsair fans on it (I forget the model) which draw their power from the one cpu pwm header on the mobo, then I have 3 140mm noctua NF-A14 3000rpm fans connected to an nzxt sentry-2 fan controller, and the two stock 140mm fans that came on the front of the case which are plugged into two other pwm headers on the board. The problem is if I set the speed of the three 140mm noctuas to anything higher than 40% on the fan controller the fans rev up and down constantly, but I dont know if its due to lack of power or the controller is faulty.
I want to replace the controller with an nzxt sentry mix 2 and then add one 120mm noctua NF-F12 3000rpm fan to the case. I would plug the new 120mm into the new fan controller, not a pwm on the mobo, becuse my bios wont let me control more than 2 pwm fans so the third fan runs at 100%, and these noctuas are loud as hell at 100%.
Im just wondering if im already putting too much strain on my psu, and if by swapping the old fan controller(which has 1 molex connection) for the sentry mix 2 (with 2 molex plugs) and then adding another fan I will blow my psu. Will it be too much for my 850w psu?
