R9 390 black screen problem

[roco smith]

hello guys i just bought a r9 390 and installed to my pc but i saw that my psu has 1 x 8-pin AUX Power Connector and 1 x 6-pin AUX Power Connector and also my psu is 550 watt. r9 390 needs 2 x 8-pin AUX Power Connector and i put one of the 8 pin into 8 pin and other 6 pin from my psu to other 8 pin. When i opened my pc, i heard windows open sound etc but it was all black screen from the start, even didnt show up bios screen. then i closed it. I really hope it didnt but do you think my r9 390 gpu got burned or something thats why it didnt show anything or it s just not enough energy and nothing happened to my gpu i hope : / ?

Just not enough power. If you got a good PSU (tell us the exact model please), you'll simply need to buy either a 2x4-pin Molex to 8-pin PCI-E adapter:

http://www.ebay.com/itm/16cm-5-8-Pi...999625?hash=item5679b394c9:g:eOgAAOSw9N1VyLKt

Or a 2x15-pin SATA to 8-pin:

http://www.ebay.com/itm/Dual-15-Pin...297991?hash=item339ee76947:g:9Z8AAOSweW5VBAIo

Are you absolutely sure you didn't get one with the card, though (the 2x4-pin Molex -> 1x8-pin PCI-E)?

By the way...

You can always take out your GPU and, um, give it a good ol' sniffing, especially on the right side. If anything happened to it, you could tell.

Good luck.

Hello, my PSU is OCZ Fatality 550W

 

[Constantine Yevseyev]

That's a pretty good one, actually. I'd say it can definitely power a single R9 390 w/o any issues (unless you have one of those heavily overclocked six-core i7 processors). So yeah, just get a power adapter if it wasn't bundled with your GPU and try again.

I have i5 4690 CPU, 1x 7200 rpm HDD, 1x SSD , 2x4 gb ddr3 1600 mhz rams and a asus dg sound card installed in my pc.

 

[Aquinus]

For what it's worth, my machine running the 390 at full throttle will draw 550-watts off the wall easily. My 390 also came with a 6-pin to 8-pin adapter. A dual-rail 550-watt PSU might struggle with the 390. I personally think that a 550 is pushing it with the 390. I would expect that the 4690 would consume less power than my 3820 which is a power whore however, my concern primary lies on the fact that the PSU can only output 450-watts on the combo of both +12v rails. If it could output 550-watt on +12v, I might think it would be enough but, it's not. Even if it were, it would be cutting it too close for comfort for my own taste.

I have to disagree with @Constantine Yevseyev , that PSU is barely if not adequate.

 

[Xzibit]

Maybe your asking too much of the PSU. @W1zzards review

• Didn't pass the Haswell compliance test (Crossload 1 load test)

• 3.3V performance in Advanced Transient Response tests

• Very low hold-up time

• Low quality caps

• Not-so-quiet operation

• Loose voltage regulation at 5VSB

• Large dimensions (for a 550 W PSU)

The 390 or any beefy GPU will just compound/expose the issues of the PSU further when stressed.

 

[Constantine Yevseyev]

@Aquinus @Xzibit Guys come ooooon, 550W is not enough for R9 390? Really? I was running a bloody FirePro S10000 (2x HD 7970) on full with my XFX, I know it's somewhat better quality than this OCZ (since it's a re-branded SeaSonic), but seriously. According to tests (http://www.techpowerup.com/reviews/Powercolor/R9_390_PCS_Plus/28.html), PowerColor R9 390 barely consumes 330W in full load. Games? That would be 230W! You're saying that it's too much to ask from this unit? That's just crazy.

Maybe your asking too much of the PSU.

How would we know? So far he didn't even get to the part when the card would turn on, because he literally put a 6-pin where 8-pin was expected. Not enough power, end of the story, the firmware should stop initializing the device and be done.

Didn't pass the Haswell compliance test (Crossload 1 load test)

This doesn't even mean anything. "Haswell Compliance" = "Supports C6/C7 Deep Sleep State", and that's all.

That's game load average. Just like Nvidias TDP it an average which means nothing if the PSU cant handle the highest power demand of the card.

Yes, you can get away with the bare minimal as long as the PSU can handle the highest power load of what ever card is in the system. He could just swap out the card and try a lower-end or switch to his iGPU

 

[Aquinus]

Guys come ooooon, 550W is not enough for R9 390? Really?

No, 450 max on +12v is a problem though. I have a 390 and turning v-sync off in City: Skylines eats up 480-watts from the wall and other games eat up to 550 on my machine. Do some research, or better yet, read my last post, I think you missed it.

Forget the part where the PSU can't do 550 watts on +12v (450w max), which is also split into two rails.

External Power - 6-pins : 1

External Power - 8-pins : 1

Minimum Power Supply Requirement : 750 watt

So I would say the psu is not enough.


OP what brand and model 390 do you have?

 

[GhostRyder]

Wait so you didn't hook up the other 8 pin on the card and instead only hooked up a 6 pin to it without an adaptor?

550 watts is enough, its the split rails that has people concerned. But either way it should boot up with it though your going to need an adaptor at least the 6 to 8 pin adaptor.

How's providing a link to a test not considered a research? OK, have some more:

If that's not considered a research, then teach me how they do it on your planet.

You know, maybe it's because you have a freaking i7-3820 running 4625MHz? And six storage devices?!

That's game load average. Just like Nvidias average TDP it means nothing if the PSU cant handle the highest power demand of the card.

The highest power demand of the card is 330W, I just posted that. You will never, ever reach it, unless you write a thoroughly optimized compute shader and feed it to the angriest driver on Earth.

That's average. Certainly doesnt tell you how PowerTune or GPUBoost spike several times a second and drop to lower overall power usage.

 

[SonicZap]

Even if the PSU wasn't enough, shouldn't the system still boot up with video? Unless I'm seriously mistaken, the graphics card is far from full load during the bootup phase.

 

[flmatter]

basically everything I have skimmed thru people are using a 650 watt psu at minimum if not the recommended 750. I feel the 550 op has is not enough and will cause issues later while gaming or pushing the card to its limits bench marking or whatever. OP needs to hook up the proper power set up first. the 550 should at least turn on but I have a feeling as soon as a load hits the psu it will just shut down. I understand trying to get by with less but there is a reason why gpu makers are suggesting 750w psu.

 

[Aquinus]

This part... Get off your high horse.

Heck, even back when I got a 6870 with a Phenom II 940 with a fraction of the hardware I have now and when I had a 520-watt PSU it was not enough to even boot. You're ignoring the obvious. I'm done with you because anything additional I can say is going to land me an infraction.

...but please, continue to be the only person claiming it's enough when it's not even working.

There's always a series of tests performed before the GPU becomes available to any kind of driver (GOP -> Windows -> some Virtual Device infrastructure). It's no wonder a card such as a freshly released R9 390 does something "advanced" in terms of checking the quality of power source, and it's most definitely possible to do this on hardware side. No electrical contact on last 2 pins found? "Go to sleep". I'm not sure though, but it seems to be the case, right?..

And that reason is wanting more money. XFX whom you just cited sell their own PSUs, they even recommend a 850W one for this card. AMD themselves do not mention any recommended wattage for R9 390 (http://www.amd.com/en-us/products/graphics/desktop/r9#).

You're ignoring the obvious. I'm done with you because anything additional I can say is going to land me an infraction.

Well first, let's both be honest here, you're done because you're out of arguments, and I'm done solely because I want to have a conversation with someone who at least can pretend that they respect other people and not just themselves. Sorry. Then, we had a "discussion" about something a year ago, and you have proven to be quite toxic. I ignored your other comments for a very long time, and it turns out there was a good reason for that. Luckily, it's up to people around you to put up with your knows-everything persona, so, yeah, bye.

*****

Sigh... Whatever, @dassan, just buy a PSU they want you to buy and be happy. If they don't believe tests performed by @W1zzard himself, then what can a guy who just occasionally posts on this forum achieve?..

Then maybe you can explain what's going on because I haven't seen you give any recommendation on what the problem could be other than using the wrong connectors which the PSU doesn't have extras of. I also don't see you owning the product either, or having had this very issue that the OP is having, both of which I have. I'm speaking from experience, you're speaking out of your ass. Congratulations, you've gotten the thread nowhere. All you're saying is, "It's not the PSU." Every time you post and someone says something that you disagree with, you become super defensive then resort to personal insults. That's not how you fix a problem, it's how you get people pissed off at you.

Tried GPU on a CX 600 corsair psu it worked, glad that nothing happened to card

Glad to hear your GPU wasn't fried. I've known people who have lost PSUs and it has taken out other components as well. Either way, it's great that you were able to test it on another power supply. Glad we cleared that up. Enjoy that GPU, buddy. I love mine.

Edit: Side note, did your 390 not come with a 6-pin to 8-pin adapter? Mine did, not that I needed it with my 1kW PSU.

No mine did not come with 6-pin to 8-pin adapter. I will buy a psu today my options are these :

Which one do you think i should get? They are pretty the same i think.

 

[Aquinus]

Either should be fine. Both have their drawbacks but, they're practically equal. The Thermaltake seems to be a little more solid on the 3.3v but, that seem to be a very minor issue. I think they'll both get the job.

Here are some reviews. I think you should make the decision for yourself IMHO.

Grats on the Nitro - got the same, worth every cent!
It really doesn't matter about the two PSUs - throw a coin ^^
