Aida64: Help interpreting anomaly in PSU and GPU graphs.

[Futurama_Firefly]

Hello,

I have a few screenshots of results from Aida64 and there is a bit of an anomaly in the PSU and GPU results. I'm worried that there may be something odd going on and wondering if someone can help me to interpret the graphs?

The first screenshot is the GPU and CPU power consumption under heavy load:

There are rather large dips in the yellow line (GPU) and it also shows up in the temperatures (light brown top line):

The voltages are fairly stable:

But I have no clue why the GPU is acting up in the stability test? Can it be the power supply or possible motherboard or is my GPU on the fritz?

Any help or interpretation would be very appreciated!

Thankyou,
Adam

I ran a GPU only stability test with Aida64 and it looks even funnier:

Any suggestion where I could look for answer would be appreciated! Googling like mad.
