Hey guys. I just got a new graphic card so i got the Corsair 750M power supply. When i replaced the power supply and started the pc i got an overvoltage problem. I see lots of people saying its usually the motherboard but can you take a look and see? Motherboard is Asus Prime A320M-K

Processor: R5 1600x

Graphics: KFA2 3070

 

Thanks in advance

Holy Shit. I am 90% sure that the board is reporting wrong. Try the old PSU again and see if it says stupidly high voltages.

I will recommend an NHu12s (or an NHd15 (maybe)) for your PC build. Quote or @ me @Prodigy_Smit for me to see your replies.

I cant. The old PSU is 550w and the 3070 needs 650w. Should i get a new motherboard or?

They're asking that you try it. If you're not doing anything with the GPU it'll be just fine with a 550W psu, the 650W is a recommendation, I ran a 5900X and 3060ti at full blast on 500W, you'll be okay with a 3070 and 1600X

As Prodigy stated, it could be bad reporting as that would insta'kill your CPU, most likely.

 

That, or the auto overclocking offset voltage is adding wrong. You'll notice the reported voltage is almost exactly double the shown voltage next to "offset mode". If it were me, I'd disable the auto-overclocking and see what happens.

Ok. Didnt know that it would be ok with 550w. So if it passes and no overvoltage. What sould i do then? What would be the problem?

As long you don't run anything graphical demanding like a game etc it should be fine... 

 

And if this over voltage problem goes away with the old psu the solution is kind of simple, you need another psu as the one you got is somehow not working properly with your motherboard at least. 

 

Also see sig, my 3070 runs fine... I set power limit to 90 and core clock - 25 and still get above average benchmark results... 

 

I also forgot to apply my settings once and nothing happened... lol. 

 

I'll still use it because better safe than sorry and performance is through the roof EITHER WAY. ;)

Kid.Lazer has the right idea.

Why haven't you reset your BIOS? Honestly thinking that's the play here. We're praying that this is a misreporting error because if it's not your CPU is as good as dead.

I'd say reset your BIOS first then introduce a new PSU, just what I'd do personally.

The CPU is at 35C shouldn't it be really hot with that much voltage? Tho I certainly don't know since there won't be any load, but I still think it should run more hot even idle?

Ok so i switched back to the old PSU and its the same problem. Did the BIOS reset with the screwdriver crosslink and same thing. The only thing i dont know is how to turn of the autooverclock since i dont know whats its name in the bios. 

 

Whats your next advice?

Ok since you reset CMOS there should not be any auto overclocking applied. But this is really a weird situation looks like the motherboard is misreporting, I can't really give any advice here as I've not seen anything like that yet. 

 

Did you actually check this before using the new PSU tho, maybe your mobo always did this?

No, with the old setup i never got that error. Wont even let me pass into windows, i have to press F1 and go into BIOS.

Simce everything else is.new and the old PSU didnt help. Would it be smart to try a new MOBO?

 

And thank you for your help so much.

I see, actually yes trying a new mobo would be smart as we can't exclude something being wrong with it... *however* if you do this use your old psu or a known good psu because this kind of still looks like the new one was causing all this... you know, something must have caused it, doubt it's the gpu tho, although you could try using your old one if you still have it. 

. But anyways, new mobo and old / known to be good psu is what I'd do probably.
