Further, noise should be the smallest concern when building a rig for hashcat. Top priority should be cooling and making sure you have appropriate parts. You’d *probably* be safe with a 1600W server grade PSU, but I wouldn’t overclock and even this is really pushing the limits.

Having a weak PSU can not only degrade performance, but it may eventually damage your hardware too.

right, i agree, but i can easly set the power limit to 125 or even 130 on the cards and i stay about 250 watts below the capacity of the PSU.  I ran a few bench marks and noticed very little difference difference with the power limit in place..

WPA/WPA2 benchmark:
No Power limit: 2230.2 kH/s
Power limit set to 125 on all cards: 2063 kH/s
Power limit set to 135 on all cards: 2107 kH/s



so that should suffice no?

Regarding noise, i don't want the wife to complain when im hashing for any considerable amount of time.
