New build problem - Short circuit when touching case

[Oh Nana]

I recently put together a new build and things run fine unless I touch the case and then it reboots.  I assume there must be a short circuit or power supply issue.  Testing the power supply seems to show good voltage and I don't see any of the motherboard screws outside the circle.  What else might cause a short? 

 

MB:  Gigabyte X570 Aorus Elite 

CPU:  Ryzen 7 3700x with stock AMD Wraith Prism cooler (CPU_Fan connector)

GPU:  EVGA 2070 Super XC Gaming

PSU:  EVGA SuperNOVA 850 G3 (80 Plus Gold)

RAM:  Corsair Vengeance LPX 16 GB 3600

Case: Cooler Master MasterCase H500

Fans: 2 200mm front   (CPU_Opt connector)

1 120mm fan  rear of case(Sys Fan 1 connector)

1 140mm fan  top of case (Sys Fan 2 connector)

 

Should I disconnect fans (other than CPU) and see if they might be an issue?  Remove the 2070 Super and try onboard video?

what exactly do you mean by touch, because there are different levels of touching a case. like with force, or grazing it, or barely touching it.

 

also does it happen everywhere on the case when you "touch" it

There is no onboard video to test with

 

Did you forget to use the standoffs?

[Oh Nana]

When I touch the left side of the case (with glass panel) it resets.  I did place the 9 motherboard standoffs in the case (2 were already installed) and lined the motherboard up with them when screwing in.  I am going to try another outlet and different UPS to see if there might be an issue there.

what kind of ups do you have?

[Oh Nana]

My UPS is APC Backups.  I think I have isolated it to touching the removable magnetic dust filter on the top of the case.  I have never had one before but could the filter on top of metal case be an issue?  I searched to see if anyone else had similar issue but didn't find anything.

didn't think they actually made something like it you can certainly remove it to see if it helps additionally the ups or outlet does not have any gfci does it? when you touch the case it does the same thing as pulling the cord (effectively speaking)

[Oh Nana]

Since removing the dust filter i can basically touch the case anywhere and no issues.  I don't know if I totally resolved the short issue.  But the removal of the filter has seemingly mitigated things.  Since I use the top fans as exhaust I feel the filter may not be as needed.
