Lag spikes in every game

Hi there,

I'm suffering from a quite weird problem,
Already since my I got my new PC (Since end April this year) I got lag spikes in almost every game (except in very light games).
It doesn't matter if it is an online game, or just offline.

The lag games up after every serveral minute(s), and the duration of the lags are like 10 to 20 seconds long,
The frames per second from frop 60 to 8-15fps.

While the lag spike is starting, the temperature of both CPU and GPU is fine.
The CPU usage of the games raises like 10-20%, and the overall CPU usage is like 70-80%.
The GPU usage drops from 95 to 20%.

I also tried to use another HDD, with 7200RPM, that should be fine in my opinion.
And I tried to update my GPU drivers too, but that didn't make sense too.

Here are my specs:

Power supply: Aerocool E85-550 550W
Motherboard: ASRock 970 Extreme3
CPU: AMD FX-8150 (8-core) @ 3600 MHz
CPU Fan: Cooler Master Hyper212 Evo
RAM: Corsair 8 GB DDR3-1600

This computer should be able to run games like GTA IV, Battlefield 3, ArmA II, Max Payne 3 etc without problems, but I'm suffering from lag spikes with all these games.

I hope someone has some advice for me.

Thanks in advance!

  1. Check out the PSU...
  2. What do you mean by that?
    I mean, the wattages are enough, so what else can I check?
  3. I think the problem is with your power supply. Firstly, I have never heard of Aerocool and you would be better off with a reliable brand such as Corsair.

    Also your graphics card needs a minimum of 30A on the 12V rail that your GPU is connected to. Your PSU according to this website ( ) doesn't have a 30A rating on any of the 12V rails.

    Therefore, even if your power supply is working properly, it isn't supplying enough amps to your GPU, and if you go with a brand like Aerocool the PSU itself may not be giving you quality power. I'm about 90% sure that that is your problem.

    Hope this helps,
  4. I don't want to waste money for a power supply if it is not the problem, but if you think this could be the problem, then I might need to take this risk.

    What power supply do you recommend that is not too expensive?
  5. What do you think about the Corsair CMPSU-600CX V2?

    That should work.
  7. I might go for the Cooler Master GX550, looks good too, and it's a coolermaster.
  8. I think I've just thrown away €70,- .

    I have the Corsair CMPSU-600CX V2 now, and still experience huge lagspikes.
