RX480 crashes system

Hi, I am having a strange issue where the RX 480 just randomly shuts the PC down. This happens to me only in League of Legends when something intensive tends to happen. The strange thing is I believe my system has plenty of power and I have zero issues with Nvidia.

As a background, I "upgraded" from a GTX 970 4GB, where I had zero issues other than the odd fps drop and a slightly loud fan, to an Asus Dual RX 480 4GB where it was OK for a couple of games in LoL, but then after the first crash in LoL it started to crash every single time I went into game. By crash I mean the computer would instantly turn off and I would have to reboot. It was OK in standard browsing/playing videos.

So I returned the 480 and bought a GTX 1070 8GB. Again, literally zero issues, played tons of games with LoL on that card. However, as I was only playing LoL at 1200p I thought a 1070 was overkill, so I sold the 1070 and bought PowerColor 8GB RX 480, my thinking being that maybe I was unlucky with a dodgey card with the ASUS RX 480 (it is currently one of the cheapest 480's after all). But I've had the odd complete computer shutdown with even with this different 480 card. It has been alot less frequent than the ASUS one, but the fact it still happens rarely is annoying/worrying.

I'm at a loss as to what is causing this because it happens only with the Radeons. I'm using DDU driver removal tool in safe mode to completely remove Nvidia drivers before installing the AMD ones, and I've even checked in regedit for Nvidia entries (none found). I have a Gold rated 850W Akasa PSU, and given that I had zero issues with both a 970 and a 1070 in the same card slots, I'm thinking it's not the PSU or the mobo?

Thing is I'd much rather keep the 480 if I could resolve the problem because I just prefer Radeon software and think the in-game colors are a little better with LoL anyway.

If anyone has any clue as to what it might be I would be really grateful. My PC specs are:

The TDP max of the GTX 1070 is 150. The RX 480 pulls more than that on AVERAGE.

So while i don't care much about TDP as far as efficiency goes (if you want to go fast - no one cares about MPG), it can give insight into why a PC isn't functioning.

While that PSU SEEMS ok, i do believe it is causing you all this trouble.

Every time you go to a high TDP card, your system fails. Basically - you ask more power of your PSU, and it has failed every time.

What happens is - everything works fine. Everything gets 12v power and is happy...
Then a game starts, and the GPU says i need more power! And demands added amps on the 12v rail.
The PSU stutters, and fails to deliver the power when it is needed - and the GPU crashes, causing system...

USUALLY the PC stays on for the most part - just the GPU crashes. You are experiencing a total system failure - the problem with that is we are only gonna be able to see the kernal power loss from the error logs (most likely)

While that PSU is highly rated - it isn't highly reviewed and that brings it's quality into question.

I would suggest getting a very, very reputable power supply brand. Seasonic comes to mind as one of the most reliable - and their PSUs are sold under a variety of names and brands.

I'd say replace the PSU.

After I updated my driver last week to version 17.2.1 I have the same issues with my 480. I tried a couple different games and the whole system restarts or shuts down within a couple minutes of play. I didn't have any of these issues before the driver update, so I will revert back to a previous driver version and see if that fixes it.
 


Rolling back drivers, for something that affects every game you play, is not a logical conclusion.
Sometimes drivers cause problems in certain games and circumstances - but rarely (never?) do publically released drivers cause instability in all games.

A more likely conclusion is that your PSU is also bad. The update fixed your RX480 and resolved its power draw issue. Now that it is able to draw full power - it is causing your system to crash because your PSU isn't great.

I just checked his PSU and found that it can deliver 70A on a single +12V rail. How can be that's not enough?
I have the same problem but with a Cooler Master V750 (62A on a single +12V rail).

That is a terrible PSU.
They can put whatever stats they want on the box, doesn't make it true.

If you actually applied load and monitored you'd see you're more likely to start a fire than ever hit 40amps.

Coolermaster makes some of the worst, most dangerous excuses for fire starters out there. Would not allow in my home, and if I did I would contact my insurance company to let them know of the hazard.

CM V750 is on tier list one. So you are telling we cannot trust these lists?

Then please tell, what PSU to order and who to trust? :)

 
The list isn't that updated and historically coolermaster has terrible PSUs.

Fact is...

You need power, can't get power, and the rig crashes.

If your rig crashes because it isn't getting power.... Then you don't have enough.

Super Butterfly if youre not in America. If you're in America get a seasonic and be done.

Changed the PSU to a seasonic G550, seems ok so far. No way getting a Cooler Master again.
