in my opinion there are only two possibilities: gfx board or mainboard. for your mainboard worked with your older card, it should be the xfx 480. the psu is by far alright.

Again, I was quoting recommended specs. Have fun getting support from a manufacturer. You know what else uses 12v rails? Hard drive motors. You know what you have in your rig. 4 hard drives that you didn't provide the make and model for. Guess what that means? No one can tell you anything, but recommended specs. Ergo krumme not being able to even ballpark what the actual load is on the rails.

I dont have any HDD in the relevant sys. Read the OP again.

I would add that a faulty PSU can be due to voltage ripple independent of max current... If the Secondary capacitors are aging or faulty the voltage will appear fine and adequate output current will get delivered to the load however the voltage will be noisy with an AC component to it... Simply take a Multimeter put it on lowest voltage setting if it's not auto ranging and make sure it's in AC NOT DC mode, probe the 12V, 5V and 3.3V rails and write down the voltage readings, the AC setting will tell you the ripple voltage, check the ATX spec for ripple tolerances and if they are out of tolerance, you might be able to recap the PSU and bring it back to working order.

But loading down a rail with bad caps will increase the ripple even more and that can easily cause system instability issues and even damage hardware over time.

You have a driver issue for sure, not a PSU issue. You need to uninstall all video drivers and use a driver cleaner maybe even a program like Ccleaner or Bleach bits and wipe it all down and get rid of any left over driver bits and then try reinstalling the Video Drivers. I am only using a Corsair 600w PSU with my MSI RX480 8gb GPU and I have my system loaded with 4 sticks of ddr4 ram,8 120m fans, 1 DVDrw, 1 HD-DVD Drive, 1 240 GB SSD, 4 4tb HDD's, and 1 USB3.0 8tb HDD and have never had one problem that your talking about and I game and watch movies all the time for hours and hours on end. Only other thing I could think of is your GPU or motherboard is faulty.

Thanks for the reply.

I did as you said. Same result.
I changed the PSU. No crash since.

Ok maybe I was wrong... PSU Then? I just find it odd that I never have had any issues with a 600w running all my hardware. Even had a 450w PSU before hand and still no issue's.. Well anyways good luck with your new PSU hope everything keeps chugging along for ya.

Which is why every single other person here has concluded that the PSU must be faulty. As in "not working as it should."

This. not a problem with the PSU rating--the PSU was just broke as a joke. Things happen.

Ok folks, I am clearly taking crazy pills.

Now, after abt 3 weeks of _solid gaming_, I am now back to the original problem. After a few seconds to max 2-3 minutes, games quit with monitor to power save and a hard reboot is required.

Thing is, I havent changed anything since I replaced the PSU for the 500W! My case has been closed all this time.

Troubleshooting:
- removed my 4.2Ghz overclock,
- downgraded Crimson to 16.11.4 which is a version which _definitely_ worked.

No avail. E.g. Tombraider (2013) plays for max 5 secs, FC3 manages a minute.

Is it possible that I shot my other PSU?

Do you have a spare PC you can test the video card in?

A friends machine?

I'd want to test that GPU in a completely different system and see if the problem follows the GPU.

Alternatively, put your old GPU back in and see if these new symptoms arise with it.

I didn't read everything ... but if you haven't, grab a spare HDD and format a fresh Windows install on it and put nothing but video drivers and Tomb Raider on it and see if it gets better.

Its definitely your PSU again. I'm assuming both were old models, used for quite a while and over time, just purely from use and time they will lose capacity and especially with GPU's that use short bursts of very high max it can overload the PSU.

This is why you need a quality PSU, but even that is no guarantee if you've used it for over 3 years. Parts get worn out in gpu's, its just natural and they can't handle the power over time.

Probably your PSU. I'd avoid PSU's with dual 12V rails.

I'm running an i7-6700K with a MSI Gaming X RX-480 in a 450W Silverstone SFX PSU just fine. I can even overclock CPU to 4.5 GHz without issue.

I am having the same problem as OP, and I have the same card (well, an XFX RS RX 480 8 GB, instead of the GTR) and exact same PSU. Like him, I tried a ton of things (different PSU with 750W and one 12V rail, different pcie slot, reinstall Windows 10 completely, newest 16.12.2 drivers, etc). I am losing my god damn mind. The new PSU seemed to make the crashes stop for 1.5 weeks, but today they started again and it has happened 3 times tonight (once in GTA V, twice in DOOM).

I previously had a Sapphire HD 7970 GHz Edition in this build for 4 years, never had any problems at all, never had a single crash. I have pretty much given up hope and am going to put my 7970 back in, possibly try RMAing the RX 480. It is very annoying since this card runs everything very well (I just have a 1080p 144Hz monitor) and otherwise breathed new life into my machine for at least a couple more years. I just can't put up with these random crashes in games though.

OP, do you have any updates? It has been a couple weeks since you posted, was wondering if anything you've tried has worked. I can't find much about our problem online and I am getting very desperate.

I strongly believe that the PSU is at fault here.

Initially I thought that since the specifications list two +12V rails at 20A with a combined power output of 576W, it might actually be a single rail instead of two. Manufacturers have been known to do this, especially Seasonic.

However, upon looking further, I found that the 620W unit has the exact specifications and rating as the 520W:
https://seasonic.com/product/m12ii-620-gm/
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=185

The only difference is that the 520W unit has no combined rating. Also, the 620W also has the same number (2) of PCI-e connectors! This is surprising, because if your PSU is rated for 100W more, surely you could have one more 6-pin connector?. Also, Seasonic has an updated version called the EVO which is a single 48A rail and it has four 6+2 pin connectors.
http://seasonic.com/product/m12ii-620-evo/

In other words, just by going from multiple rail to single rail design, you get more than twice the output to power your graphics cards. This suggests to me that it is indeed a 2x20A +12V design, and it probably does not have any provisions against imbalanced loading, which can lead to all kinds of funny stuff:
http://www.tomshardware.com/forum/306437-28-single-rail-multiple-rails-eternal-question-answered
http://www.jonnyguru.com/forums/showthread.php?t=3990

So I suspect this is what is happening: the RX 480 with 8-pin connector is drawing power from the same rail that is supplying power to your CPU and other components and unable to distribute the load the PSU is shutting down. This didn't happen with the HD 6950 because it got its power from 2 PCI-e connectors distributed over both rails. I bet that if you had a card that requires a single 6-pin connector, it would have no trouble running off a single rail.

Also, at the time you got this PSU I don't think there were that many cards that needed only one 8-pin connector. Most cards which needed more than one 6-pin connector came with 2x6pin or 8+6pin configurations.

Yeah, but as I said, I tried a new PSU with 750W that had a single 12V rail (Corsair CX750M), and after 1.5 weeks the same crashes started to happen, to the point where it crashed 3 times in one night. Again, this is also after trying a different PCIE slot, complete clean install of Windows, etc. (everything mentioned in previous posts).

Anyway, that was last night, which is why I made the frustrated post yesterday (as it really does not seem to be the power supply, despite what everyone is saying). Nevertheless, I returned the CX750M today and bought an EVGA 850 BQ (850W, single 12V rail). I don't know, everyone seems so sure it's the power supply, so I figured I'd give another one a shot. If the issue still persists even after this third PSU though, I think we can safely say something else is going on (I'll probably try RMAing the card to XFX if it happens again, as a last ditch effort).

Today I just played DOOM through 4 levels, no crashes (last night I could only get through 1/2 of one), so let's hope the trend continues. I will revisit this thread soon and update it with my results, in case people find this on Google when searching about the same problem.

why don't you just get the card RMA'ed at this point?

If using 3 different PSUs always creates the problem, although I agree clean power is critical ( i have a 750W Gold PSU for that very reason), it just seems odd that 3 separate PSUs would be having a problem driving this system. Only an elite 10% actually uses a nice power supply, most people run just fine with whatever they happen to have.

It hasn't crashed yet on the third one, I just got it a few hours ago. If it does, I'll RMA and update the thread.

Alright, so it crashed on the third one, as expected. So, I called up XFX and they said since it was still in the return period (I bought it on Black Friday from Best Buy, so it was eligible for returns til Jan 15, per their holiday period policy), it would probably be a better idea to just go to Best Buy and swap it for another one off the shelf, instead of RMAing it (which would take 2 weeks).

So, I returned mine and got another off the shelf. Same XFX RX 480 RS 8 GB, but I noticed this one said "Rev Z.4" on the tag whereas my original one said "Rev Z.1". I guess they changed something with the manufacturing process. Also the new one says ASIC quality of 72% in GPU-Z, whereas my original was 66%. So who knows, maybe my original card was just garbage and this new one should be higher quality. Anyway, I'm going to continue playing DOOM and see if any crashes occur. If not, I guess we know it was a bad GPU after all. If so, at least we know it's not the PSU or GPU, and maybe I just need a new mobo or something. I'll keep you guys updated.

Hope it works out for you, because that is damn frustrating.

But I also hope that you keep posting after, because that username is hilarious.

Welp, I played through most of DOOM, thought this was finally it, everything was fine - then just now, boom, same freeze as before, screen turned one color (gray this time, it's different every time), buzzing sound, had to restart, same as before.

At this point I think it's safe to say it's not the PSU (tried 3 different ones) or GFX Card (tried 2 different RX 480s). I've seen posts on other forums about how the RX 480 can draw too much power from the PCIE slot and this can damage some older motherboards. I have an ASRock Z77 Extreme4 that's a little over 4 years old, with an i5 3570k. I don't know, at this point all there is to still replace is the CPU, mobo, and memory. That's gonna run me up around $400.

You guys don't think it could be a hard drive / ssd going bad, do you? I don't think so, considering this only happens in game, and generally drive problems result in a blue screen or something with an error message, not like what I'm getting.

Oh well, this has been frustrating as all hell. Been 1.5 months since I got this card and have been dealing with this issue. At least it only happens in-game, sigh. I'm going to call XFX support and see if they have any other ideas, but at this point it looks like this card just doesn't like my system ;_;

I dont know if it will make a difference but try PCIe at 99Hz in BIOS and see if it will do the same.

Also, do you use any old USB device ?? like old mouse or keyboard ?? or any USB external HDDs etc ?? disconnect any external device and see if it will freeze again or not.

Im in the same (or simillar) boat. How did you solve this problem? The difference is that my PSU completely shuts down while gaming. Tried Metro 2033 redux and as the main game starts my system shuts down almost immediately. I can power on the system again only after reconnecting the power cable of the PSU. Also tried heaven benchmark 4.0, it can last for 30sec-1min then system shutdown.

The specs:

-Asus M5A99FX Pro R2.0
-Kingston Hyperx Fury 8Gb
-FX8320 (non overclocked)
-XFX RX480 8GB GTR Black (RX-480P8DBA6). Non overclocked.
-Cooler Master V750W semi modular PSU, 62Ampers on a single +12V rail: http://www.coolermaster.com/powersupply/gaming-v-sm-series/v750s/
The PSU has four 6+2 connector, im using two of them with the 2x 6+2 to 8pin adapter (got with the xfx card) but tried every combination.
Tried different PCIe 16x slots.
-Win10 Pro 64bit
-Radeon sw: 17.4.3 (Driver Packaging Version 17.10.1711-170410a-313248C-CrimsonReLive) with clean install.

The GPU is new (ordered last week), other hardware is 2,5years old approx.

Power counsumption and temps while running heaven benchmark 4.0:
CPU: 40C (CPU cooler: Cooler Master Hyper 212 EVO)
GPU: max 72C
GPU power consumption: approx 100-105W while running the benchmark (Idle: 7-8W).

I changed the card from a GTX660Ti, did not expreience any problem in the last 2.5years.

Please tell if anybody has some idea. Thanks.
