Question my pc is stuttering but I have a good PC?

[xImgn7]

Hello, so basically I upgraded my pc a while ago and since then my frames have been dropping (or staying the same) when they should be higher.

My specs:

-Motherboard: Asrock steel legend b450
-Ram: Crucial Ballistix 2x8GB ddr4 3000 mhz
-Gpu: Rtx 3060 12GB
-Cpu: Ryzen 5 1600AF
-Power supply: Mars gaming MII750 750w

I used to get 90 fps at Destiny 2 for example, and now I get the same but sometimes it drops even more to like 50, 40 or even 30..
I have all the recent drivers installed, I tried to lower all settings in-game, but it's still quite unplayable for me.
I really don't know what to do anymore.

But a horrible power supply unit.

Power supply: Mars gaming MII750 750w

That's a junk PSU. Remove it before it causes any damage.

Kindly replace it asap, and grab yourself a high quality PSU. Don't use this Mars branded PSU to power up the RTX 3060.

Oh, I see. I didn't think that the problem was the PSU, since it's brand new. Would I be fine with just a 650w gold certified? Or do I need to go with a 750w? e.g:

EVGA SuperNOVA 650 G6 650W 80 Plus Gold Full Modular​

Nvidia recommends a min 550 Watts PSU for the RTX 3060. The above EVGA PSU should be enough to power up your rig. You can also get the 750 Watts, just to have some extra headroom for future upgrades, or, if the price difference between the 650 vs 750 Watts is not very high.

Also the 1600 is a aged. Once you get the psu, at some point consider trading up to something like a 5600 or higher. That would likely help your fps as well.

I agree with both of the above posters. Your PSU is junk and your CPU is most likely holding your GPU back (assuming that you're gaming at 1080p).

Upgrade CPU and PS and let u s know how it improves.
