Hey guys,
Not sure if i am posting in the right area, please let me know if i am :P.
So ive only recently built my PC from scratch using two hardware components from my old rig (Corsair h75 liquid cooler, Corsair CX600w PSU).

Rig:
MSI H270 Gaming Carbon Pro
i7 7700 (Non K)
Corsair h75
Gigabyte GTX 1070ti 8gb
Corsair Dominator ddr4 2x4gb 3600mhz Ram
Corsair CX600w PSU 120mm Radiator

So my performance btw is an outstanding upgrade from my previous build, however i just can help but think that my GPU is not getting enough power from my PSU. I say this because my GPU power consumption is around the 50% mark in AC Origins. With my fps rates dropping around 20 fps with significant power dips and gpu usage dips. (I have monitored all of my games with similar results).
NOTE: These power drops happen every minute or so.

With my CPU usage sitting consistently at 90+% i cant see there being any issues with bottlenecking.

Temperatures for CPU 45-50c in game
Temperatures for GPU 40-45c in game

Any help would be very much appreciated :D
 
what its sounds like to me an heat problem. i had an asus strix that would do the same problem, it turns out the VRM had no heat sink so they GPU was throttle when they hit max temp, this would happen ever 30-40 seconds ones they hit the limit.
install a program called MSI Afterrurner and run the GPU fans at max speed, play a few games and see if the problem continues

The problem with running a none K CPU is they don't really get hot and most PC cooling(fans) run off CPU temp, 45-50c on the CPU is nothing your fans will remain at low.
the second problem is GPU fans spin up bassed on GPU temp and not VRM temp, 40-45c is cool so the fans dont spin up and the VRM can get VERY hot.


The GPU i was using would game at 55/60c but the VRM was hitting 90c
 
Could well be the PSU. The old CX600 was already not a true 600W and it had cheap components inside. Degrading would therefore occur at a faster rate (in theory) to cause power output to lower even more. They weren't very well rated for heat either, so it could be the PSU that's getting too hot and lowering output. Since that PSU doesn't really belong in a system with a 1070Ti, I wouldn't bother finding a spare PSU to test and would just buy a good PSU.
 
I'd say 90+% CPU usage does point to bottlenecking, is the GPU consumption higher?

I've used a CX500M to feed a 970 and pull 350W at the wall so it's certainly possible the PSU can feed that card, condition/age excluded.

If you ramp up GPU fan speeds to hopefully lower VRM temperatures, what happens?
 
i have just installed HWinfo64 and cannot see the vrm temps anywhere, perhaps theres a setting i can access?
Monitoring my gpu tdp by the looks of it there is only around 60% tdp being supplied when actually playing the game. the minute i pause the game the tdp rises to 90+%

Game menus often drive the graphics card crazy. What is the GPU usage during gaming? Higher than the CPU?

Graphics cards don't often supply VRM temp readings externally btw.
 
The GPU usage runs from 60% to 80%, with the CPU running consistently at 92-94% After just playing on 100% fan speed i have found that the performance has been smoother. However i did get a really bad gpu usage drop to literally 0%...
Almost seems like the gpu usage isnt as consistent as it should be hence the wild variation in fps.
in game my fps is always altering in range from 40fps to 68+fps
 
TBF i am shocked a 7700 cant feed the GPU. if the CPU is around 90% i would say there is a bottle neck there.

what setting are you gaming on mid? the lower the setting the more the CPU as to work and less the GPU as to work.
Crank upthe setting in game to high or ultra


Edit: i missed the line in the main post about @CPU usage
 
I am playing on very high graphics settings, i have just noticed something about my CPU the base clock is 3.60ghz however task manager is saying its running 3.49 ghz all the time.

the turbo state of your cpu should be...

turbo frequency (1 core) 4,200 MHz (4.2 GHz, 4,200,000 kHz) +
turbo frequency (2 cores) 4,100 MHz (4.1 GHz, 4,100,000 kHz) +
turbo frequency (3 cores) 4,100 MHz (4.1 GHz, 4,100,000 kHz) +
turbo frequency (4 cores) 4,000 MHz (4 GHz, 4,000,000 kHz) +

if your dropping to 3.5Ghz there is something wrong there

maybe i am expecting too much performance when running around in city scenes, whenever i am playing out of cities i get 90-120 fps

no the CPU shouldn't be at 90% and your should be getting 3.9/4Ghz constant

What irresolution is your monitor, also enable v sync(or G sync) in the games menu
 
Come to mention it, when installing all my drivers the processor driver illuded me somewhat. According to intel driver & support assistant application all my drivers were up to date... which didnt make sense... I of course just trusted intels judgement

the CPU should just work out of the box.
 
Okay so ive just changed my power management to 100% and my CPU is now running constantly at 4.00ghz with a vcore of 1.040v. Could i increase the voltage even more to gain just under 4.2 ghz? or would this be unwise?

4Ghz on all cores is where it should be, unless you edit bios it will not turn over 4ghz on all cores.
+0.5Ghz over 8 threads is a good gain, it should help remove the bottle neck. what game are you testing with is it a CPU heavy game.

Have you tried playing the games?
the 1070ti should kill 144hz @ 1080 no problen,
 
Ok No worries. so i am testing it on AC origins. ive found performance is much better still finding the CPU running at 100% with GPU running around 70-80% in built up cities. when i leave the city i get 100% CPU usage with 100% GPU Usage.
im going under the assumption this is normal?

move the setting to max/ultra, you may be under loading the GPU. put more load on the GPU and let the CPU take less
The GPU should be at 100% i find in games my CPU is around 40/50%
