Problem With my Pc

[xFabstar]

Hello Guys,

first up, I am German and I'm sorry if my english isn't the best.

Today I was playing some GTA V online on ultra settings and my graphics card (rx vega 64) got to a usage of 70% maximum (max 67 celcius). After quite some time of playing (3-4 hours) my monitors were instant black screen but the pc kept running. When I turned off the pc it wouldnt even start or only with blackscreen. If I then unuplug my power supply and hit the power button, plug it in and run it, it's fine. After quite some time again the same thing happens again. I then did a gpu stress test and after like 4 mins the same thing happened again... so I assume its something wrong with my gpu but I have no clue what exactly...

Also if I put up the fan speed from 40 to 100 in MSI Afterburner I hear no difference in terms of sound it doesnt even get faster..... 

Would be great to get some help, and I hope its not defect or something like that..

Yours, Fabian

What PSU do have?

1st, check gpu temps under load, if temps are fine second best guess is what MadAnt250 is proposing. Tell us what your PSU is. It's possible that if powe draw was very close to your max psu capacity it might have degraded and is unable to output same wattage as when it was new.

Ok, I checked the temps and they are fine, maximum was 65 celcius. My PSU isnt old yet (like 1month old) and its a Corsair VS650. I was running completely fine the whole time and it firstly appeared yesterday..

It definitely could be the VS power supply. By all accounts they're not very good, and Vega cards are hard on power supplies. Are you at least using two separate 8 pins and not the 8+8 combo PSUs normally have?

The 2 8 Pins I use are on the same cable if you mean that, as long as I know its only those 2 8 pins I have..

 

So if you say its the PSU for sure, why exactly did it appear yesterday and not instantly when I firstly started the pc?

Also which PSU should I get for my build then?   I have a ryzen 5 2600 and a RX Vega 64 on a B450 from Asus

I also have a old PSU at home, it's a Combat Power CP 750W Plus, but I dont think its really good

Yeah, that could be an issue.

When you first start the PC, the GPU isn't under any load so it won't pull much power. Once you put it under heavy load in a game like GTA V, it starts eating a lot more, and it can suddenly spike for a second or so to a really high wattage number and then drop back down. IDK much about the actual innards of PSUs, but as far as I know the cheaper ones won't handle a spike like that very well. I'd call in JohnnyGuru but people seem to have run him off the forums.

The corsair CX (2017), CXM, TXM, RM/RMx/RMi, and all the higher ups are solid. EVGA's G2, P2, and T2 units are excellent. Seasonic has some solid PSUs, avoid any of the Focus series though, they have problems with Vega that even Seasonic themselves acknowledged. IDK too much about any other brands.

Alright, thanks for the help. I guess I will get a new one then, I hope that it the PSU that's causing the problems... It's just weird that I was playing Z1 Battle Royale for a week and nothing happened. Yesterday the problem occured in GTA V and now I also get that in Z1, in a game in that I never had that before... I guess the PSU is just not good..

Hopefully it is the PSU though, that should be a lot cheaper to replace than the GPU. Could always start up a thread in the PSU section, stating your local market/currency, budget, and use case. The PSU nerds over there should be able to help you out a lot better than I can.

Ok, thank you really much. The good thing is that I build the pc a month ago and I can still get everything replaced.. So in worst case I dont need to pay for a new GPU. I can even return the old PSU and order a new one luckily.

Oooooo nice! Happy you decided to boot up GTA and discovered this problem before it was too late for that. Would definitely replace the PSU first, if you still have issues after that then the GPU would be the next suspect. I'd run DDU then clean install the GPU drivers again and undervolt to see if that makes the GPU behave before returning it though. Which model Vega 64 do you have?
