    Question PSU too noisy after installing new GPU

    Hey everyone.

    I recently switched out my EVGA GTX1060 SC with an EVGA RTX2060 Super XC Ultra; I also switched some chinese brand front intake fans with a couple of Corsair ML140 and adjusted the fan curve accordingly. Yet, while playing and doing some benchmarks on Cinebench, Valley or Heaven or simply playing a game, I kept noticing high fan noise/speed coming from my PC, but only when there's any load on it. I tried to adjust all the fans on my machine (GPU, CPU, 2 intake fans, 1 exhaust fan) and the noise kept on going.

    Finally, after opening my tower and checking every fan by ear I noticed that the one that that's ramping up is the one from my PSU (Thermaltake TR 600W). The thing is, unless I have been blaming the high rev noises to other components beforehand, I never noticed this happening before, and it only happens with any kind of load. If I let my PC be, eventually it goes back down to quiet, but it does takes some time.

    My question is: should I be worried? Is this a telltale sign that is time to change my PSU?

    Current setup:

    • Ryzen 5 3600 with stock cooler (and PBO enabled)
    • EVGA RTX 2060 super XC Ultra with a light overclock
    • ASUS TUF B450M Gaming Plus motherboard
    • 2x8GB DDR4 3000 ram sticks (HyperX with RBG, forgot the model)
    • Thermaltake TR 600W non-certified, since it's kind of old
    • 2x Corsair ML140 fans as intake
    • 1x upHere 120 led fan as exhaust
    • Corsair Spec-01 case



    Due to the pandemic and my country of origin, I don't have that many options to replace my PSU, I mostly can get either:

    • Corsair CX line (450w to 750w)
    • EVGA W and N line (from 500w to 750w), a couple of BQ (from 700w to 850w) and GQ line (650w, 750w and 850w)
    • One Corsair RM line (1000w, kinda overkill)
    • A couple of fancy Asus ROG psu (550w and 800w, kinda expensive)



    Thanks in advance for any and all help.

    The Corsair CX550 is enough power and it has an LLC topology with DC to DC making it better than the EVGA's. The RM1000 is stupid overkill. As are the Asus ROG's.

    Thanks for the quick reply.

    A followup question, then: is there any difference in quality between the different watt tiers in the cx line? Also, I also have access to the CXm line, could that also be an option?

    I was wondering and pretty hesitant because I've been reading that there is so much to know between the different ratings and lines of different manufacturers and I want to make a good purchase that can last me this and maybe another build/upgrade.

    Thanks again for any info on this as well.

    So, even though the CX-M is "better" because it is semi-modular, and therefore often more expensive, the CX (non-M) is more technologically advanced in the platform is uses.

    Both use DC to DC for the +3.3V and +5V rails. But unless modularity (modular cables) is a MUST, I will always go for the more updated LLC platform.

    Thank you very much.

    So it seems that the best choice is the cx line. I think I can snag a CX650 for the equivalent of $10 to $15 less than the CX550 (prices in my country are like that, what can I say).

    Cheers!

    Well, shoot. If the CX650 is less than the CX550, then do that.

    Thank you for the help, your incredibly educated advice was the one that drove me on the right path.

    Got the cx650 as I told you and it's already installed and running perfect.

    Is there any way to mark this post as solved?

    Cheers!

    No. vBulletin doesn't work like that.

    We usually wait for the thread to go off topic or bumped 10 years later, then we lock it.
