rx 480 Bought a new PSU and now my RX 480 doesnt work unless undervolted

[Jose Varela]

I changed from a Gamemax GP-500 (500w bronze plus) to a Sharkoon Silent Storm 650w gold plus. And now my GPU only works perfectly undervolted in power limit radeon wattman as low as -50, tried -40 choppy gameplay, -30 even more choppy gameplay,-20 choppy gameplay some games crash pc. Is this a PSU Voltage problem. Or is my GPU to old to handle a new PSU?. Just in case at stock wattman settings so no power limit change it can play some games perfectly, but it dies in games like Witch it, Rainbow 6, Remnant from the ashes, and recently the beta of riders republic(just after the first cinematic jump into gameplay). 

 

Also changed from a b550m pro vdh wifi mobo to a b550m gaming edge wifi

 

In case this is the full rig 

Msi rx 480 gamingx 8gbs
x2 G.Skill trident Z 3600mhz(xmp on)
Ryzen 5800x
Msi b550m gaming edge wifi
Sharkoon Silent Storm 650w gold plus

If it works fine with the old psu, I think it is a psu problem. Never heard of that brand before so I am a little sketched out about it.

Sounds like a PSU issue, Sadly Not all PSU's are labelled properly. It sounds like a real sketchy power supply. sounds like the 650W PSU is not really a 650W unit, probably is a 450 or 500.

Sharkoon is actually listed in A tier in the PSU tier list under low priority unit, so it's definitely not a sketchy psu by any means

The old one may not be accurate either.  Also there’s more to a PSU than watts.  There’s how clean the power is and other stuff.  Possible the video card has an issue with one of those other things.  I’m not knowledgeable about the specifics of power supplies though there are those here that are.  I just look at the PSU tierlist which is a thing made by people that are.   I’m mostly concerned with safety myself.  I want a PSU that fails in a way that is not dangerous for the other parts of the computer, though I suppose one that allows things to work in the first place is also needed.  There is a PSU section much like the graphics card section in which the tierlist resides

The unit itself can be sketchy, as its not properly supplying the power. Stuff happens and you can get a bad unit. An EVGA 1600 T2 Unit recently Fried itself and a few components it was hooked up too, Just because its on a list saying it should be good doesnt mean much.

So you are saying youd love the Gigabyte 750 and 850m Units?  It could be both but if the GPU was working fine with the 500 PSU, it just sounds like the 650 May have an Issue and could be RMA'd and such. Its hard to say what it exactly is, but from the info given it seems to be a Power related issue if the GPU was working fine before hand.

That particular one or just A model by that company?  Brand name is not 100% reliable with PSUs any more than it is with anything else. Seems anyone is capable of making junk occasionally.

Huhwhat?  No.  Not even sure how you got there.
 

I’m just stating a possibility.  There apparently isn’t any known good here is all. I don’t know what his video card likes about that PSU.

You mentioned you wanted safe powersupply, those two units have been tested and shown to be pretty explosive when they fail. Was a joke  

 

Since theres 2 new parts, its not exactly a simple one or the other.

Ah.  I knew about the explosiveness.  It seemed like a dig.  Jokes go over my head a lot especially if they include sarcasm.  I’m not good at detecting sarcasm.  Me and that guy from Big Bang theory. 
 

I agree it isn’t simple.

I have a warranty for the psu still, would you recommend using it to get a replacement or should i get another one. Taking in consideration that i live in Chile(south america) and not many PSUS arrive here

Thank you for your time. Will be reporting later if the PSU was really the problem. To also keep future buyers from my same PSU to be aware also.

does not seem like psu issue, it seems like heating issue. your new psu is better than your old one and should work fine.,

Thats the thing, i dont think this is a heat issue, i literally rendered blender animations one week before the change. And when i changed the PSU those same renders would crash my PC on the same stock settings,

Came back to this, changed the psu to the be quiet and sadly the problem continues. So i guess my gpu is just overheating i guess

What case is this build in? I just recently changed cases and had an issue where I was over heating my PSU, but it was from the hot air coming out of other components. 

If the PSU is overheating, the system should just shut down. It sounds to me like your GPU is overheating. What are the temps on it when it starts acting up?

The case is the be quiet 500dx and i dont check the temps when on stock settings. But it is almost instantly and the PC doesnt shut off. The display just dies and the gpu fans go wild until i manually turn off the pc. The strange thing is it didnt happened before with my old PSU and now that i changed 2 times the PSU to a one that is now better i just guess there most be something with the voltage my gpu is receiving or my GPU is indeed just overheating and with my old psu it just didnt reached higher temps that it used to. Wich might explain why i need to undervolt it in wattman to -50 in power limit in order for it to work

You're only using PSU cables that came with the BeQuiet right?

My guess here would be that your GPU was overheating and causing some issues. You had thought it was PSU issues so you changed PSUs and then didn't change all the cables. Sharkoon power supply cables will not work in any other brand. Same with Corsair. Corsair cables will not work in any other brand, Gigabyte, EVGA, all that same way. They're all different on the power supply side, but the same on the component side.

Yeah i returned all the cables with the sharkoon when i used the warranty so i am only using be quiet cables, the only thing i am not using is the power cord. Because i dont have the power cord transformer thats compatible with my wall outlet. so i am using an old power cord thats compatible. But i have read online that it shouldn't matter

Was this gpu repasted?  If it’s a gpu overheating issue the paste may have dried up if it’s never been repasted.

No the GPU hasnt been repasted that was my last troubleshoot option if anything i had done fixed it. Because i dont know how to open this and then repaste it safely
