Power consumed by GPU rolling back while underload?

[Mr.Meerkat]

So I'm currently trying to overclock my Asus RX470 Strix and well, I have a small (or should I call it large) issue.

The issue I'm having right now is where the power draw would randomly decrease while stressing and benchmarking where this causes the fps to become capped to 20fps no matter the game or application for about 5 seconds before going back to normal.

 

This is what I'm talking about:

GPU load is still 100% but temps and power draw decreases and has a rollercoaster effect... (BTW, the idling temps are kinda high as I have a custom curve where the fans are idle up to 65C rather than 50C stock)

 

Any ideas? 

 

@Energycore, That's what I was talking about stuttering and what not, 1350MHz with +100Mv core and +50% power limit doesn't even seem to be achievable ;-;

What temps are the VRMs getting to? If they're throttling, the GPU wouldn't get enough power and therefore clock down.

Hold on, checking with Hardware info

...now it's just triggering OCP or OVP or OPP or UVP or SCP on my PSU...can't even get heaven to start playing with the overclock applied...(as in it loads for 5 seconds and bam, computer restarts) but heaven runs fine if I don't have the overclock applied...for fuck sakes, what iz going on?

Well, for a PSU of that calibre, it'd be a short circuit or something to trigger OCP... Try reinstalling drivers (with DDU ofc).

If the PSU is not up to snuff, software isn't going to fix it.

I'll see, worst case scenario, I'd RMA it and well I have a XXX sitting around doing nothing anyway so I guess it's not actually that bad when you have a back up PSU anyway

True but it's probably not the PSU as I've drawn roughly 900-950watts off it's 12V rail before (let's not talk about how I was powering 2 OCed 290Xs and 2 stock 7950s off it) and it worked perfectly fine
