Have you tried a USB ground isolator like this sort of thing https://www.amazon.com/SMAKN-Isolator-Digital-Isolation-Industrial/dp/B00XXPO4UG/ref=sr_1_2?ie=UTF8&qid=1503826368&sr=8-2&keywords=usb+isolator+ground+loop
If the interference goes away when you unplug the USB from the DAC, yet the DAC is still hooked into the powered speakers, then you're hearing a ground loop. This is because you're grounding your equipment together through the analog 3.5mm cable to the DAC then USB to your PC.
I used to get this from plugging the 3.5mm headphone output from a phone into my line in on my Saffire DAC, then once I plugged in the USB to keep the battery charging on the phone, it would make a loop.
A couple thing may help you.
One is going with a dual balanced XLR with a 3.5mm adapter:

or dual 1/4" TRS -

(there are many variations of these out there).
The other option is to put a ground loop isolator in line with your analog unbalanced RCA signal:

You could also try a USB filter (some have inputs for an external power supply) - https://www.amazon.com/SMAKN-Isolator-Digital-Isolation-Industrial/dp/B00XXPO4UG/
(Or even just getting a better USB cable with ferrite chokes)
Or of course, last resort - just get a cleaner, pro DAC, like a Focusrite Scarlett Solo

You should ask people on amazon if it gets rid of ESD. Some DACs will enhance audio while not eliminating interference. You might buy it and find that you will need something like this.

It completely depends on whether or not the ESD only affects your 3.5mm jacks. I use the X470 Gamin Aorus motherboard which has dedicated DAC-Up ports for isolation.
Try a USB ground isolator then. Something like this.
