Low Fps after new PSU installed

[the_fox]

Hello,

I have a recent problem that popped up. After having a failing PSU, Corsair GS 800w, replaced with a Evga 650w Gold, games have begun dropping FPS quite bad, from around 100 - 150 to <20. This includes all games, even older ones from 1998.

I have ran Chkdsk, no issues reported on OS nor storage drive. Nothing from Antivirus. Nothing from Memtest86 after 3 passes. I have pushed down everything as hard as I could, made sure what looked like should be plugged in, is plugged in. Not overheating, case was cleaned thoroughly when the PSU was replaced. CPU maxes around 60c, GPU around similiar, +-10c.

I have cleaned the old GPU drivers with DDU and installed the most up to date one.

Win7
4x4GB Corsair Vengeance Ram
i7-4790k
Gtx 970
Asus z97-A
EVGA 650W 80+

Peripherals such as keyboard, router etc.

Nothing has changed besides the PSU.

What PSU is it exactly?

How is the GPU hooked into the PSU?

Using one daisy chained cable or two separate cables?

Run this and post the link it gives you at the end. Maybe it'll tell us what to look at for the fps drops

Let me see if this works right, and I manage to respond to the right thread.

The PSU is a EVGA 650w 80+, unfortunately I am not sure about your other questions, as I was not the one that put it together. GPU is hooked into what I believe is a 8 piece connector.

That doesn't tell me anything....

Here you go.

Unfortunately I am not sure how to check what you are asking for, beyond the brand of the PSU. I did not put it together and I am not sure I am knowledgeable enough to distinct between the cable management you asked of. I did take a few pictures of it after I opened it up the other day, if that might be of any help?

Seems everything is working well except your hard drives. Are the games in question installed on one of them? Can you try a game that isn't?

Yes, all games are installed on it. Though, it is the disk I ran ChkDsk on, and it came back with no issues. I will try to move one or two of the games over to the other drive and report back. Though, even doing basic things such as opening browsers, IE and FF, switching between them, going through Discord etc has lagged out on a few occassions. None that should be on the drive in question.

Going by the report, the 2TB drive reporting 49.4% Average is the one where the games are installed, the other one 250GB 27.8% is the one where I mainly keep random files and backups/old files. Going by that, I have a feeling it will run even worse once I move a game over.

EDIT:

It appears I was wrong, one of the games that has seen a +100 FPS drop is installed on the other drive, and not the 2TB one, where the majority of my other games are. Thusly games from both drives have equally as bad of a drop after the new PSU.

I should also note that the monitor is not plugged into the mobo/using the onboard card, as the 970 is detected as the unit being used.

Thought i'd bump this, as I now have new information.

While playing a game now and having the FPS drop, I decided to run the User Benchmark, and it now came back with vastly different results.

You can't run it while gaming... It fully loads your parts on it's own. If they're already doing another task it'll show 0th % Everytime

I repeated the test, just this time closing the game while it was lagging and running Benchmark, getting similiar/same results.

This is about 5 minutes after closing the game. Though, I suppose I have no real option left but to send it back in at this point, if this one doesn't point to anything concrete I can do. Thanks for the help!

The only oddity I see is your cpu running at 4.0ghz and seemingly not Turbo boosting.

Is that anything that would cause such issues? Currently running OCCT to test the CPU/GPU. GPU doesn't quite seem to agree with it, but CPU is handling it well as far as I can tell. Only thing that sticks out is "CPU Overclock -80%" about 10 mintues in. No idea if this means anything, though.

Running Asus GPU Tweak II and setting it into a OC mode squeezed a bit more juice out of it while gaming, and also made it last a bit longer before dropping FPS, without OC mode I would have around 10 - 20 FPS, with it enabled, around 30 - 40 FPS.

Temps for both CPU and GPU are still good, <70c CPU while OCCT testing, <75c GPU while gaming/stress testing with FurMark.

EDIT:

Uninstalled drivers with DDU, reinstalled with the "Clean install" option. Issue still continues, so I think I will throw in the towel on this one.
