audible speaker interference from PC components?

[fage6043]

I'm not entirely sure which category to post this query in, as what I've read so far dictates that the 'problem' could be almost 'anything'.🙁

Thank you in advance for any help, here's the scoop:

I recently built a new Gaming PC, and ever since my existing M-box (external sound card) and Rokit 5 studio monitors (speakers) have been buzzing, clicking, hissing, and popping, seemingly in relation to any computing processes. For example, they make noise in conjunction with mouse scrolling/movement, gaming, ProTools use, etc.. I feel like its important to note that the headphone output of the M-box is FINE... and I'm using the appropriate unbalanced TRS cables for the Rokit 5.

I've scoured the internet for information and found that it could be:

-Realtek Audio drivers (I'm using an external sound card though i.e. the M-Box)
-ASUS z170 Pro Gaming Motherboard (known issues with onboard audio apparently)
-Cheap USB cable (Between computer and M-box, possibly needs Ferrite Beads)
-Ground Loop (All of my components are plugged into one power strip, which is plugged into a grounded outlet though)
-PSU (I bought a high quality one)
-Graphics Card (ugh)
-Metal Case (as opposed to my old PC which had a plastic one)
-Speaker/USB cables running parallel to Power cables (I don't really have this anywhere)
-The list goes on...

All I know is that there was never any problem before. Something in my new PC is not co-operating with the M-box/Rokit 5 speakers.

Here is my PC's build:

NZXT S340 Glossy Black Steel ATX Mid Tower Case
EVGA 120-G1-1000-VR 80 PLUS GOLD 1000 W
ASUS Z170 PRO GAMING LGA 1151
Intel Core i7-6700K 8M Skylake Quad-Core 4.0 GHz LGA 1151 91W
Corsair Hydro Series H100i V2 Extreme Performance Water / Liquid CPU Cooler. 240mm
G.SKILL Ripjaws V Series 32GB (4 x 8GB) 288-Pin DDR4
ASUS GeForce GTX 970
SanDisk SSD PLUS 2.5" 480GB SATA III Internal Solid State Drive
Seagate Hybrid Drive ST1000DX001 1TB

Thanks again!

1| You do realize that your PSU is completely overkill, right? You can get away with 550W's of power from your unit.
2| You also forgot to include your OS, the sound card's model and the version of your Rokit monitors.
3| Since you're on a DAC that is driven off of a USB port, it's moot to fiddle around with your Realtek audio though since you've stated this, see if disabling the onboard sound card alleviates the issue.
4| Use of the ferrite choke can reduce the popping but it will not eliminate it since the power source/your system is being subjected to a grounding issue thus the static(popping).
5| Have you made sure your motherboard BIOS is up to date?
6| You can try and get a certified electrician to take a look at the wall outlet and subsequently the wiring in your house since improper wiring can cause the grounding issue.
