Hey.
 
I've just assempled a new system, using entirely new components. Our subject of interest in this case is the EVGA SuperNOVA 650 G2 power supply.
The first thing we all probably do is run a benchmark, just to see our baby do its thing. So I run Unigine Heaven and suddenly, I hear rather strange ticking noises coming from the power supply.

After a longer while of troubleshooting here are my conclusions:
They only occur when the graphics card is under moderate to high load. Tried Furmark (to max out the card) and there were no ticking noises.
Usually there are two or three ticks every 30 seconds or so when playing new AAA titles.
Also, no noises during CPU stress testing.
 
From the power-hungry parts of my PC I have a Core i7 7700K (no O/C) and a Zotac GTX 1080 AMP! (Has two 8-pin power inputs).
 
Any ideas what could this be?
Thank you.
 
Meanwhile, I've been trying to file a support request, but I haven't been able to do so, the website just keeps giving me error 159 when trying to post it. What's up with that?

Hello,
 
I am sorry to hear this. Its possible that there is some type of obstruction to the fan causing this ticking noise.
 
I see you purchased your 650 G2 very recently. Do you have the opportunity to exchange the unit with the retailer?
 
If not, I have started and RMA ticket for you to submit for replacement.
 
Please visit  to submit your RMA.

Once the RMA is approved you will receive an RMA approval email with all relative information for completing the process.
 
Please let us know if there is anything else we can assist you with in regard to your EVGA products.
 
 

Thank you for your response.
I most definitely can tell, with full confidence that it's not the fan being obstructed. The ticking is too irregular.
Upon closer inspection (having the entire system laid out, out of the case) I was able to locate (more or less) the source of ticking. It's from the general area where the largest coil is, inside the PSU.
